Introduction
The annual production of methanol exceeds 40 million tons and continues to grow by 4%
per year. Methanol has traditionally been used as feed for production of a range of chemicals
including acetic acid and formaldehyde. In recent years methanol has also been used for other
markets such as production of DME (Di-methyl-ether) and olefins by the so-called methanol-to-
olefins process (MTO) or as blend stock for motor fuels.
The production of methanol from coal is increasing in locations where natural gas is not
available or expensive. However, most methanol are produced from natural gas. Several new
plants have been constructed in areas where natural gas is available and cheap such as in the
Middle East. There is little doubt that (cheap) natural gas will remain the predominant feed for
methanol production for many years to come.
The capacity of methanol plants has increased significantly only during the last decade.
In 1996 a world scale methanol plant with a capacity of 2500 MTPD was started up in
Tjeldbergodden, Norway [1]. Today several plants are in operation with the double of this
capacity e.g. [2].
Plants with capacities of 10,000 MTPD or more are considered and planned for example
for the production of methanol for the MTO process [3]. Given the substantial investment in such
large scale plants there is considerable incentive to maximize single line capacity to take
advantage of economy of scale. This design project will describes the state of the art methanol
synthesis technology with focus on very large plants with a capacity of 00000 MTPD or more.
All commercial methanol technologies feature three process sections and a utility section
as listed below:
Synthesis gas preparation (reforming)
Methanol synthesis
Methanol purification
Utilities
-
In the design of a methanol plant the three process sections may be considered
independently, and the technology may be selected and optimized separately for each section.
The normal criteria for the selection of technology are capital cost and plant efficiency. The
synthesis gas preparation and compression typically accounts for about 60% of the investment,
and almost all energy is consumed in this process section. Therefore, the selection of reforming
technology is of paramount importance, regardless of the site.
Methanol synthesis gas is characterized by the stoichiometric ratio (H2 CO2) / (CO +
CO2), often referred to as the module M. A module of 2 defines a stoichiometric synthesis gas
for formation of methanol. Other important properties of the synthesis gas are the CO to CO2
ratio and the concentration of inert. A high CO to CO2 ratio will increase the reaction rate and
the achievable per pass conversion. In addition, the formation of water will decrease, reducing
the catalyst deactivation rate. High concentration of inerts will lower the partial pressure of the
active reactants. Inert in the methanol synthesis are typically methane, argon and nitrogen.
A comprehensive survey of methanol production technology is given in [4]. In the
following a brief description is given covering technologies available for the three process
sections.

1.0 History and General Information on Methanol
1.1 History
1.1.1 Methanol
In their embalming process, the ancient Egyptians used a mixture of
substances, including methanol, which they obtained from the pyrolysis of
wood. Pure methanol, however, was first isolated in 1661 by Robert Boyle,
when he produced it via the distillation of boxwood. It later became known as
pyroxylic spirit. In 1834, the French chemists Jean-Baptiste Dumas and
Eugene Peligot determined its elemental composition.
They also introduced the word methylene to organic chemistry, forming it
from Greek methy = "wine" + hl = wood (patch of trees). Its intended origin
was "alcohol made from wood (substance)", but it has Greek language errors:
wrong Greek word used for the French word bois = "wood"; wrong Greek
word combining order influenced by French usage.[dubious discuss]
The term
"methyl" was derived in about 1840 by back- formation from methylene,
and was then applied to describe "methyl alcohol." This was shortened to
"methanol" in 1892 by the International Conference on Chemical
Nomenclature. The suffix -yl used in organic chemistry to form names of
carbon groups, was extracted from the word "methyl."
In 1923 the German chemists Alwin Mittasch and Mathias Pier, working
for BASF, developed a means to convert synthesis gas (a mixture of carbon
monoxide, carbon dioxide, and hydrogen) into methanol. A patent was filed
Jan 12 1926 (reference no. 1,569,775). This process used a chromium and
-
manganese oxide catalyst, and required extremely vigorous conditions
pressures ranging from 50 to 220 atm, and temperatures up to 450 C. Modern
methanol production has been made more efficient through use of catalysts
(commonly copper) capable of operating at lower pressures, the modern low
pressure methanol (LPM) was developed by ICI in the late 1960s with the
technology now owned[citation needed]
by Johnson Matthey who is a leading
licensor of methanol technology.
The use of methanol as a motor fuel received attention during the oil crises
of the 1970s due to its availability, low cost, and environmental benefits. By
the mid-1990s, over 20,000 methanol "flexible fuel vehicles" capable of
operating on methanol or gasoline were introduced in the U.S. In addition,
low levels of methanol were blending in gasoline fuels sold in Europe during
much of the 1980s and early-1990s. Automakers stopped building methanol
FFVs by the late-1990s, switching their attention to ethanol fueled vehicles.
While the Methanol FFV program was a technical success, rising methanol
pricing in the mid- to late-1990s during a period of slumping gasoline pump
prices diminished the interest in methanol fuels. Additionally, methanol is
highly corrosive to rubber and many synthetic polymers used in the
automotive industry, whereas ethanol is not.[5]
In 2006 astronomers using the MERLIN array of radio telescopes at
Jodrell Bank Observatory discovered a large cloud of methanol in space, 288
billion miles across.[6][7]

1.1.2 The Production of Methanol Synthesis
Supp (1990) and Olah et al. (2006) present good overviews on the
characteristics of methanol and its production methods. This section is largely
based on these reference books. Another source may be found at wikipedia.
Methanol has a history extending back to about 1661, when Boyle
succeeded for the first time in recovering methanol from crude wood vinegar.
The component was re-discovered in 1822 by Taylor, after which in 1835 Von
Liebig succeeded in clarifying the chemical structure of methanol. In the
hundred years following this, methanol was recovered to an increasing degree
as wood alcohol by distilling wood.
In 1923, Mittasch and his staff succeeded in first producing methanol from
carbon monoxide and hydrogen (synthesis gas or syngas) using a catalyst.
Methanol was recovered together with a whole series of other components
containing oxygen, and the catalyst only had very short cycle times. Patart
then described a methanol synthesis process using hydrogenation active
metals, and metal oxides stated to be the catalyst. This led to a first
commercial plant. This process required vigorous conditionspressures
ranging from 3001000 atm, and temperatures of about 400 C. Modern
methanol production has been made more efficient through use of catalysts
(commonly containing copper) capable of operating at lower pressures.
At the beginning of the thirties, a series of commercial plants went into
operation in the USA, with capacities per plant of 100 to 500 tons/day, using
chromic acid activated zinc oxide catalyst. As early as 1935, it was recognized
that copper-based catalysts provided considerable advantages for methanol
synthesis, permitting considerably lower pressures and, above all, lower
temperatures. But these catalysts were extremely sensitive to sulphur
components. After development of suitable syngas purification systems,
-
mainly to remove sulphur, the first Low-Pressure Methanol process was
brought onto the market by Imperial Chemical Industries Ltd (ICI), Great
Britain. At that time, Lurgi Gesellschaft fr Wrme und Chemoteknik from
Germany also developed a low-pressure methanol process, which, contrary to
the ICI quench reactor, applied a tubular reactor cooled with boiling water.
Most of the methanol plants in the last 20 years operate according to the ICI
or Lurgi processes, while numerous high-pressure units have been converted
to the low-pressure system in the second half of the last century.
1.2 General Description
Methanol is also known as methyl alcohol, wood alcohol, wood naphtha or wood
spirits. It is a chemical with formula CH3OH. It is the simplest alcohol, and has a
characteristic of light, volatile, colorless, flammable, liquid with a distinctive odor
that is very similar to but slightly sweeter than ethanol. Methanol can be used as an
antifreeze, solvent fuel and also as a denaturant for ethanol as it is a polar liquid at
room temperature. In anaerobic metabolism of many varieties of bacteria and in
ubiquitos condition, methanol produced naturally. Therefore, that is why there are
small amount of methanol vapour in the atmosphere. In atmosphere, Methanol burns
in air forming carbon dioxide and water:
2 CH3OH + 3 O2 2 CO2 + 4 H2O
-
Methanol flame is almost colorless in bright sunlight because of its toxic properties.
Methanol
1.3 Usage
-
The three largest derivatives of methanol are formaldehyde, methyl tertiary butyl
ether (MTBE) and acetic acid. However, methanol is seeing growing demand in fuel
application such as dimethyl ether (DME), biodiesel and direct blending into
gasoline.
Formaldehyde is used mainly to make amino and phenolic resins which are
employed in the manufacture of wood-based products such as panels, flooring and
furniture.
The main use for MTBE is an octane booster and oxygenate in gasoline.
However, it has been phased out following its contamination of underground water
supplies and the removal of the oxygenate mandate and liability protection. MTBE
will continue to be vital for fuel quality and cleaner emissions. As countries look to
remove sulphur and lead and reduce aromatic content in the gasoline pool, MTBE
will make a significant contribution to improve fuel quality.
Acetic acid has a number of outlets of which the two largest are vinyl acetate
monomer and purified terephtalic acid. Global demand for acetic acid has been
growing at a steady 4%/ year with PTA sector growth at double this rate driven by
polyester demand. In the area of petrochemical feedstocks, there has been
considerable interest in methanol-to-olefins(MTO) and methanol-to-propylene(MTP)
technologies with projects underway in China. The first MTO units in China were
started up in August 2010.
Methanol is also used for the basis of many other chemical products:
- The largest solvent use for methanol is as a component of windscreen wash
antifreeze. It can also be used to extract, wash, dry and crystallise pharmaceutical
and agricultural chemicals.
- Methlamines are used as intermediates in a range of speciality chemicals with
applications in water treatment chemicals, shampoos, liquid detergents and animal
feeds.
-
- Methyl methacrylate is employed in the production of acrylic polymers.
- Dimethyl terephthalate is used to make polysters although PTA is preferred
feedstock.
- Methanol and sodium chlorate are used to produce chlorine dioxide, a bleaching
agent for the pulp and paper industry.
- Glycol esthers are solvents used in acrylic coatings and newer high-solids and
waterborne coatings.
- Methyl mercaptan is used an intermediate in the production of DL-methionine, an
amino acid supplement in animal feeds.
Fuel uses to grow:
The use of methanol in fuel applications is expected to have a big impact on
future demand. Methanol can be used in biodiesel plants have been built, there has
been uncertainty in the biodiesel industry. Methanol is increasingly being used to
make DME , which can be employed as an alternative to diesel, a supplement to
liquiefied petroleum gas (LPG) and in power generation. The largest DME market in
China where it is blended into LPG. The DME industry in China is suffering from
capacity.

2.0 Process in Producing Methanol
2.1 Process Selected and Selection Criteria
This section will explain the reason why the selected process has been chosen and
the disadvantages of the unselected processes.
Nowadays, there are several ways of producing methanol (CH3OH) in this world.
All of the processes have their own advantages and disadvantages. It is important to
choose the most efficient process in order to have a good and almost perfect
production of methanol. Here are the lists of the processes or step in producing the
methanol.
1. Synthesis Gas
2. Synthesis Methanol
3. Catalytic Conversion of Methanol
4. Methyl Alcohol
For this mini design project, we have decided to choose synthesis gas process for
producing the methanol. The synthesis gas is so far the best way in producing
methanol because it has more advantages compared to the other processes and it is
also being used commercially by many plants worldwide. Most methanols are
produced using either a high-pressure process or a low-pressure process. In the high-
pressure process (above 275 bars), synthesis gas is made by reforming natural gas and
forming carbon dioxide to balance the excess hydrogen by the equation
CO2 + 3H2 CH3OH + H2O
This, in effect, produces more methanols. In the low-pressure (50 to 100 bars)
methanol processes, the excess hydrogen is purged from synthesis loop and is not
-
used to produce methanol. In this method, a large reformer must be built in order to
produce the equivalent amount of methanol. Commercially available cu-ZnO-Al2O3
catalyst permits production of the desired product with high selectivity. The main
advantages of the low-pressure process are lower investment and production cost,
improved operational reliability and greater flexibility in the choice of plant size.
Stand-alone Auto Thermal Reforming (ATR) at low steam to carbon (S/C) ratio is the
preferred technology for large scale plants by maximizing the single line capacity and
minimizing the investment. The ATR produces a synthesis gas well suited for
production of both fuel grade and high purity methanol.
Here are the disadvantages of the other processes that have not been selected.
a) Synthesis Methanol
-
Synthesis methanol will produced three unwanted reaction which need a
further consideration and eventually will cause a high capital cost. Under this
reaction, CO will reacts with the walls of the reactor and produces iron
carbonyl which deposits on the catalyst and accelerates its deactivation which
is not good for a plant. This and the other disadvantages of the high pressure
operation led to the development of the low pressure process using copper as a
component of the catalyst.
b) Catalytic Conversion of Methanol
For catalytic conversion of methanol, there are too many flaws and
disadvantages that lead to the inefficient production. By using this process to
produce methanol, it will eventually produce several by-product which is
paraffins, olefins and aromatics. The extra separation or procedure needed to
set up to in order to deal with undesired by-product. Olefins are intermediates
in the conversion of methanol to aromatic hydrocarbons over zeolite. This
process is basically focusing on how to increase the olefin production instead
of methanol.
c) Methyl Alcohol
Basically methyl alcohol was produced from synthesis gas and it is also
obtained by the oxidation of methane using natural gas as the feedstock.
However, by using this process, only 60 percent of methanol produced which
the natural gas not fully converted. This means this process are quite similar
with synthesis gas but the fact that it is not being practiced by many company
in this world is a major disadvantage. This process also not focusing on
producing methanol but it is mainly on the production of methyl alcohol.
However methanol can be produced by purified with distillation.
-
2.2 Process Descriptions
Autothermal reforming (ATR) features a stand-alone, oxygen-fired reformer.
The autothermal reformer design features a burner, a combustion zone, and a catalyst
bed in a refractory lined pressure vessel as shown in Figure 3
Figure 3. Autothermal Reformer
The burner provides mixing of the feed and the oxidant. In the combustion zone,
the feed and oxygen react by sub-stoichiometric combustion in a turbulent diffusion
flame. The catalyst bed brings the steam reforming and shift conversion reactions to
equilibrium in the synthesis gas and destroys soot precursors, so that the operation of
the ATR is soot-free. The catalyst loading is optimized with respect to activity and
particle shape and size to ensure low pressure drop and compact reactor design.
The synthesis gas produced by autothermal reforming is rich in carbon monoxide,
resulting in high reactivity of the gas. The synthesis gas has a module of 1.7 to 1.8
and is thus deficient in hydrogen. The module must be adjusted to a value of about 2
before the synthesis gas is suitable for methanol production. The adjustment can be
done either by removing carbon dioxide from the synthesis gas or by recovering
-
hydrogen from the synthesis loop purge gas and recycling the recovered hydrogen to
the synthesis gas [6]. When the adjustment is done by CO2 removal, a synthesis gas
with very high CO/CO2 ratio is produced. This gas resembles the synthesis gas in
methanol plants based on coal gasification. Several synthesis units based on gas
produced from coal are in operation, this proves the feasibility of methanol synthesis
from very aggressive synthesis gas. Adjustment by hydrogen recovery can be done
either by a membrane or a PSA unit. Both concepts are well proven in the industry.
The synthesis gas produced by this type of module adjustment is less aggressive and
may be preferred for production of high purity methanol.
Methanol Synthesis and Purification
In the methanol synthesis conversion of synthesis gas into raw methanol takes
place. Raw methanol is a mixture of methanol, a small amount of water, dissolved
gases, and traces of by-products.
The methanol synthesis catalyst and process are highly selective. A selectivity of
99.9% is not uncommon. This is remarkable when it is considered that the by-
products are thermodynamically more favored than methanol. Typical byproducts
include DME, higher alcohols, other oxygenates and minor amounts of acids and
aldehydes.
The conversion of hydrogen and carbon oxides to methanol is described by the
following reactions:
CO2 + 3 H2 CH3OH + H2O (-H298K, 50Bar = 40.9 kJ/mol) (1)
CO + 2 H2 CH3OH (-H298K, 50Bar = 90.7 kJ/mol) (2)
CO2 + H2 CO + H2O (-H298K, 50Bar = 49.8 kJ/mol) (3)
-
The methanol synthesis is exothermic and the maximum conversion is obtained at
low temperature and high pressure. Thermodynamics, reaction mechanism, kinetics,
and catalyst properties are discussed in [9].
A challenge in the design of a methanol synthesis is to remove the heat of reaction
efficiently and economically - i.e. at high temperature - and at the same time to
equilibrate the synthesis reaction at low temperature, ensuring high conversion per
pass.
Different designs of methanol synthesis reactors have been used:
Quench reactor
Adiabatic reactors in series
Boiling water reactors (BWR)
A quench reactor consists of a number of adiabatic catalyst beds installed in
series in one pressure shell. In practice, up to five catalyst beds have been used. The
reactor feed is split into several fractions and distributed to the synthesis reactor
between the individual catalyst beds. The quench reactor design is today considered
obsolete and not suitable for large capacity plants.
A synthesis loop with adiabatic reactors normally comprises a number (2-4) of
fixed bed reactors placed in series with cooling between the reactors. The cooling
may be by preheat of high pressure boiler feed water, generation of medium pressure
steam, and/or by preheat of feed to the first reactor.
The adiabatic reactor system features good economy of scale. Mechanical
simplicity contributes to low investment cost. The design can be scaled up to single-
line capacities of 10,000 MTPD or more.
The BWR is in principle a shell and tube heat exchanger with catalyst on the tube
side. Cooling of the reactor is provided by circulating boiling water on the shell side.
-
By controlling the pressure of the circulating boiling water the reaction temperature is
controlled and optimized. The steam produced may be used as process steam, either
direct or via a falling film saturator.
The isothermal nature of the BWR gives a high conversion compared to the
amount of catalyst installed. However, to ensure a proper reaction rate the reactor will
operate at intermediate temperatures - say between 240C and 260C - and
consequently the recycle ratio may still be significant.
Complex mechanical design of the BWR results in relatively high investment cost
and limits the maximum size of the reactors. Thus, for very large scale plants several
boiling water reactors must be installed in parallel.
An adiabatic catalyst bed may be installed before the cooled part of the BWR
either in a separate vessel or preferably on top of the upper tube sheet. One effect of
the adiabatic catalyst bed is to rapidly increase the inlet temperature to the boiling
water part. This ensures optimum use of this relatively expensive unit, as the tubes are
now used only for removal of reaction heat, not for preheat of the feed gas. This is
illustrated in Figure 5, which compares the operating lines in identical service for
BWRs with and without adiabatic top layer.
-
Figure 5: Temperature and methanol concentration profiles in BWR reactors with and without
adiabatic top layer
The installation of the adiabatic top layer in the BWR reduces the total catalyst
volume and the cost of the synthesis reactor by about 15-25%. The maximum
capacity of one reactor may increase by about 20%.
A boiling water reactor with adiabatic top layer will be installed in a 1000 MTPD
methanol plant in China.
The last section of the plant is purification of the raw methanol. The design of this
unit depends on the desired end product. Grade AA methanol requires removal of
essentially all water and byproducts while the requirements for fuel grade methanol
are more relaxed. In all cases the purification can be handled by 1-3 columns, where
the first is a stabilizer for removal of dissolved gases.

3.0 Market Analysis
3.1 Supply and Demand
The objective of market analysis is to provide the pleasant appearance of methanol
market. It is also important to provide opportunities for the world market which it can be
categorize into two categories. The first categories is to attract many investors to invest in
the plant that is going to be build and the second one is to provide the a wide range of
possible site to market for the products and also to find the potential target client to market
their products.
There are few countries that produce methanol in the world. The country that produces
larger scale of methanol is The United States of America and China. The demand of
methanol especially in Asia countries such China is expected to increase as well as for the
demand for the world. From late August 2010, in just two months, the domestic Methanol
Market prices rose about 50%. At present, East and South China methanol market prices
rose or as high as 50% to 53%.
Methanol is widely consumed by many countries around the world. Hence, there is no
surprising to know that many countries imported methanol for domestic used such as
Malaysia, Thailand and many more.

PART 4
4.0 Site Selection
4.1 Potential Site Location
Several sites in China have been taken into consideration. These locations are
industrial site for various kinds of industries. These sites are located close to the
source of raw materials and also close to major forms of transport, which are road,
rail, sea ports and airports.
Xu Dong Da Jie 303
Xu Dong Da Jie 303 is located at Wuchang District in Wuhan City. Wuhan
City is a major transportation hub, with dozens of railways, roads and
expressways passing through the city. Wuchang was one of the three cities that
merged into modern-day Wuhan, the capital of the Hubei province, China. It
stood on the right (south-eastern) bank of the Yangtze River, opposite the mouth
of the Han River. The historic center of Wuchang lies within the
modern Wuchang District, which has an area of 82.4 square kilometers and a
population of 1,003,400.
Xu Dong Da Jie is located 11.2 km from Wuhan Port and only takes 18
minutes to reach there. Wuhan Port is located centrally between Beijing
and Guangzhou (Canton) and between Shanghai and Chongging, it is called the
thoroughfare of nine provinces. It is an important hub for transportation, with
many roads and railways meeting here. Wuhan Tianhe International Airport
situated 19.2 km from the port. Furthermore, the chosen location is located
27.5km from Xian Xilan Natural Gas Co.Ltd Hubei Branch which was the main
supplier for the methanols plant.
-
Xu Dong Da Jie is the most potential location for plant site because it is
located in the Wuhan City which is an important center for economy, trade,
finance, transportation, information technology, and education in Central China.
Wuhan has currently attracted about 50 French companies, representing over one
third of French investment in China, and the highest level of French investment in
any Chinese city. Therefore it is easier for our plant to develop and enter Frenchs
market.
Distance from:
Wuhan port : 11.2km
Xian Xilan Natural Gas Co.Ltd Hubei Branch : 27.5 km
Zhongnan Hospital of Wuhan University: 3 km
Bank of China 24-hour Self- service Bank : 4.4 km
4.2 Transport
The location Xu Dong Da Jie 303 is convenient and efficient because of easy
access to the rest of the world due to its closeness to the international shipping
lane and its connectivity with other modes of transport. Designation of Wuhan
Port as the most important port in the Wuhan City with an area of more than
70,000 sq km will become a convenient logistics hub of the Yangtze River and
Central China, a modern base for a variety of industries and an ecologically
friendly home for urban dwellers by 2020. The aim in china of making the Wuhan
Port the largest port in Asia make it more accessible and vibrant place in the near
future.
-
4.3 Availability of Labor
The current population estimation for Wuchang is 1,003,400 people. It is clear
that it will be plenty of labors available in that area. The forecasted benefits are
increase in business and employment opportunities.
4.4 Utilities and Facilities
Infrastructural facilities such as road accesses, electricity supply, water
supply, gas supply and telecommunications are readily available at Xu Dong Da
Jie 303. There also have availability of ancillary services and facilities such as
banking, hospital and fresh water supply.

Cooling water : 21yuan/m3
RM 9.72/m3
Electrical power : 2.5fen kW/h RM 0.12 kW/hr
4.5 Land
Sufficient suitable land must be available for the proposed plant and for future
expansion. The land should be ideally flat, well drained and have suitable load
bearing characteristics. A full site evaluation should be made to determine the
need for piling or other special foundations. Particular care must be taken when
building plants on reclaimed land near the ocean in earthquake zones because of
the poor seismic character of such land.

By considering the plant site and extra site for future build up, the estimation of
land to buy is 3.5 acres which is approximate 14164 m2.
Figure: Plant estimation
4.6 Climate
Adverse climatic conditions at a site will increase cost. Abnormally low
temperatures require the provision of additional insulation and special heating for
equipment and pipe runs. Stronger structures are needed at locations subject to
high wind, snow or earthquakes.
Wuhan's climate is humid subtropical with abundant rainfall and four
distinctive seasons. Wuhan is known for its oppressively humid summers, when
dew points can often reach 26 C (79 F) or more. Because of its hot summer
weather, Wuhan is commonly known as one of the Three Furnaces of China,
along with Nanjing and Chongqing. Spring and autumn are generally mild, while
winter is cool with occasional snow. In the recent thirty years, the average annual
rainfall is 1269 mm, mainly from June to August; annual temperature is 15.8-
17.5, annual frost free period lasts 211 to 272 days and annual sunlight duration

is 1810 to 2100 hours. Extreme temperatures have ranged from 18.1 C (1 F)
to 42.0 C (108 F).
Recently according to the China Earthquake Network Center a strong
earthquake with a 7.2 magnitude, struck eastern Burma (20.8 Degrees North and
99.8 Degrees East) at 21:55 on March 24 (Beijing Time), Tremors were felt in
many parts of Yunnan Province. Because the epicenter was very close to the
borders between Burma and China, people in some areas of Yunnan felt strong
tremors.
From March 31st to April 3rd
2011, a strong cold air will sweep across eastern
parts of China, Inner Mongolia, north and northeast China, areas north of the
Yellow River and Huai River, Jianghan Area and other areas which is nearby
Wuhan City, causing a substantial drop in temperature (an average drop of 8
10 and 1214 in some areas). Moreover, a moderate gale will sweep over
eastern Inner Mongolia, northeast China, north China and other places.

5.0 MATERIAL SAFETY DATA SHEET
5.1 METHANOL
5.1.1 PRODUCT IDENTIFICATION
Product Name: Methanol
Formula: CH3OH
Synonyms or Generic ID for Methanol: Carbinol; Methyl alcohol; Methyl
hydroxide;
Monohydroxymethane; Wood alcohol; Wood naptha; Wood spirits;
Columbian spirits; Methanol
5.1.2 HAZARD IDENTIFICATION
1. Appearance: Colorless liquid, Flash Point: 12C, 53.6F.
2. Danger! Poison! May be fatal or cause blindness if swallowed. Vapor
harmful.
3. Flammable liquid and vapour: Harmful if swallowed, inhaled, or
absorbed through the skin. Causes eye, skin, and respiratory tract irritation.
May cause central nervous system depression. Cannot be made non-
poisonous.
4. Target Organs: Eyes, nervous system, optic nerve.
5. Potential Health Effects:
Eye: May cause painful sensitization to light. Methanol is a mild to
moderate eye irritant. Inhalation, ingestion or skin absorption of methanol
can cause significant disturbance in vision, including blindness.
Skin: Causes moderate skin irritation. May be absorbed through the skin
in harmful amounts. Prolonged and or repeated contact may cause
-
defatting of skin and dermatitis. Methanol can be absorbed through the
skin, producing systemic effects that include visual disturbances.
Ingestion: May be fatal or cause blindness if swallowed. Aspiration
hazard. Cannot be made nonpoisonous. May cause gastrointestinal
irritation with nausea, vomiting and diarrhea. May cause systematic
toxicity with acidosis. May cause central nervous system depression,
characterized by excitement, followed by headache, dizziness, drowsiness,
and nausea. Advanced stages may cause collapse, unconsciousness, coma,
and possible death due to failed respiratory failure. May cause
cardiopulmonary system effects.
Inhalation: Methanol is toxic and can very readily form extremely high
vapour concentrations at room temperature. Inhalation is the most
common route of occupational exposure. At first, methanol causes CNS
depression with nausea, headache, vomiting, dizziness and incoordination.
A time period with no obvious symptoms follows (typically 8-24 hrs).
This latent period is followed by metabolic acidosis and severe visual
effects which may include reduced reactivity and/or increased sensitivity
to light, blurred, doubt and/or snowy vision, and blindness. Depending on
the severity of exposure and the promptness of treatment, survivors may
recover completely or may have permanent blindness, vision disturbances
and/or nervous system effects.
Chronic: Prolonged or repeated skin contact may cause dermatitis.
Chronic exposure may cause effects similar to those of acute
exposure. Methanol is only very slowly eliminated from the body.
Because of this slow elimination, methanol should be regarded as a
cumulative poison. Though a single exposure may cause no effect, daily
exposures may result in the accumulation of a harmful amount. Methanol
has produced fetotoxicity in rats and teratogenicity in mice exposed by
inhalation to high concentrations that did not produce significant maternal
toxicity.
-
5.1.3 FIRST AID MEASURES
1. Eyes: In case of contact, immediately flush eyes with plenty of water for a t
least 15 minutes. Get medical aid.
2. Skin: In case of contact, immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes. Get
medical aid immediately. Wash clothing before reuse.
3. Ingestion: Potential for aspiration if swallowed. Get medical aid
immediately. Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. If
vomiting occurs naturally, have victim lean forward.
4. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
5. Notes to Physician: Effects may be delayed.
6. Antidote: Ethanol may inhibit methanol metabolism.

1. General Information: Ethanol may inhibit methanol metabolism. As in any
fire, wear a self-contained breathing apparatus in pressure-demand,
MSHA/NIOSH (approved or equivalent), and full protective gear. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Use water spray to keep fire-exposed
containers cool. Water may be ineffective. Material is lighter than water and
a fire may be spread by the use of water. Vapors are heavier than air and
may travel to a source of ignition and flash back. Vapors can spread along
the ground and collect in low or confined areas.
-
2. Extinguishing Media: For small fires, use dry chemical, carbon dioxide,
water spray or alcohol-resistant foam. Water may be ineffective. For large
fires, use water spray, fog or alcohol-resistant foam. Do NOT use straight
streams of water.
5.1.5 ACCIDENTAL RELEASE MEASURES
1. Spills/Leaks: Use water spray to disperse the gas/vapor. Remove all sources
of ignition. Absorb spill using an absorbent, non-combustible material such
as earth, sand, or vermiculite. Do not use combustible materials such as
sawdust. Use a spark-proof tool. Provide ventilation. A vapor suppressing
foam may be used to reduce vapors. Water spray may reduce vapor but may
not prevent ignition in closed spaces
5.1.6 STORAGE AND HANDLING
1. HANDLING: Wash thoroughly after handling. Remove contaminated
clothing and wash before reuse. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof equipment.
Avoid contact with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container tightly
closed. Do not ingest or inhale. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open flames. Use

5.2 METHANE
5.2.1 PRODUCT IDENTIFICATION
Product Name: Methane
Formula: CH4
Chemical name: Methane, Saturated Alphatic Hydrocarbon, Alkane
Synonyms: Methyl Hydride, Marsh Gas, Fire Damp
5.2.2 HAZARD IDENTIFICATION
1. Emergency overview
Methane is a flammable, colorless, odorless, compressed gas packaged in
cylinders under high pressure. It poses an immediate fire and explosion
hazard when mixed with air at concentrations exceeding 5.0%. High
concentrations that can cause rapid suffocation are within the flammable
range and should not be entered.
2. Acute potential health effects:
Route of exposures
Eye contact: No harmful affect.
Ingestion: Not applicable
Inhalation: Methane is nontoxic. It can, however, reduce the amount of
oxygen in the air necessary to support life. Exposure to oxygen-deficient
atmospheres (less than 19.5 %) may produce dizziness, nausea, vomiting,
loss of consciousness, and death. At very low oxygen concentrations (less
than 12 %) unconsciousness and death may occur without warning. It
should be noted that before suffocation could occur, the lower flammable
limit for Methane in air will be exceeded; causing both oxygen deficient and
an explosive atmosphere.
Skin contact: No harmful affect.
-
3. Potential health effects of repeated exposure:
Route of entry: None
Symtomps: None
Target organs: None
Medical conditions aggravated by exposure: None
Carcinigenicity: Methane is not listed as a carcinogen or potential
carcinogen by NTP, IARC, or OSHA Subpart Z.
5.2.3 FIRST AID MEASURES
1. Eye contact: No treatment necessary.
2. Ingestion: Not applicable
3. Inhalation: Remove person to fresh air. If not breathing, administer
artificial respiration. If breathing is difficult, administer oxygen.
Obtain prompt medical attention.
4. Skin contact: No treatment necessary.
5. Notes to physician: Treatment of overexposure should be directed at the
control of symptoms and the clinical condition.
5.2.4 FIRE FIGHTING MEASURES
FLASH POINT: AUTOIGNITION: FLAMMABLE RANGE:
-306 F (-187.8 C) 999 F (537 C) 5.0% - 15%
1. Extinguishing media: Dry chemical, carbon dioxide, or water.
2. Special firefighting instructions: Evacuate all personnel from area. If
possible, without risk, shut off source of methane, then fight fire according
to types of materials burning. Extinguish fire only if gas flow can be
stopped. This will avoid possible accumulation and re-ignition of a
flammable gas mixture. Keep adjacent cylinders cool by spraying with large
-
amounts of water until the fire burns itself out. Self-contained breathing
apparatus (SCBA) may be required.
3. Unusual fire and hazards explosion: Most cylinders are designed to vent
contents when exposed to elevated temperatures. Pressure in a cylinder can
build up due to heat and it may rupture if pressure relief devices should fail
to function.
4. Hazardous combustion products: Carbon monoxide
5.2.5 ACCIDENTAL RELEASE MEASURES
Steps to be taken if material released or spilled: Evacuate immediate
area. Eliminate any possible sources of ignition, and provide maximum
explosion-proof ventilation. Use a flammable gas meter (explosimeter)
calibrated for Methane to monitor concentration. Never enter an area where
Methane concentration is greater than 1.0% (which is 20% of the lower
flammable limit). An immediate fire and explosion hazard exists when
atmospheric Methane concentration exceeds 5.0%. Use appropriate
protective equipment (SCBA and fire resistant suit). Shut off source of leak
if possible. Isolate any leaking cylinder. If leak is from container, pressure
relief device or its valve, contact your supplier. If the leak is in the users
system, close the cylinder valve, safely vent the pressure, and purge with an
inert gas before attempting repairs.
5.2.6 STORAGE AND HANDLING
1. Storage: Store cylinders in a well-ventilated, secure area, protected from the
weather. Cylinders should be stored upright with valve outlet seals and
valve protection caps in place. There should be no sources of ignition. All
electrical equipment should be explosion-proof in the storage areas. Storage
areas must meet National Electrical Codes for class 1 hazardous areas.
Flammable storage areas must be separated from oxygen and other oxidizers

at least 5 ft. high having a fire resistance rating of at least _ hour. Post No
Smoking or Open Flames signs in the storage or use areas. Do not allow
storage temperature to exceed 125 F (52 C). Storage should be away from
heavily travelled areas and emergency exits. Full and empty cylinders
should be segregated. Use a first-in first-out inventory system to prevent full
containers from being stored for long periods of time.
2. Handling: Do not drag, roll, slide or drop cylinder. Use a suitable hand
truck designed for cylinder movement. Never attempt to lift a cylinder by its
cap. Secure cylinders at all times while in use. Use a pressure reducing
regulator to safely discharge gas from cylinder. Use a check valve to prevent
reverse flow into cylinder. Never apply flame or localized heat directly to
any part of the cylinder. Do not allow any part of the cylinder to exceed 125
F (52C). Use piping and equipment adequately designed to withstand
pressures to be encountered. Once cylinder has been connected to properly
purged and inerted process, open cylinder valve slowly and carefully. If user
experiences any difficulty operating cylinder valve, discontinue use and
contact supplier. Never insert an object (e.g., wrench, screwdriver, etc.) into
valve cap openings. Doing so may damage valve causing a leak to occur.
Use an adjustable strap-wrench to remove over-tight or rusted caps. All
piped systems and associated equipment must be grounded. Electrical
equipment should be non-sparking or explosion-proof.
