  • THE PATH TO REFINED COALTHE MILESTONES OF INNOVATION

    BY GEOASIA / APRM ALLIANCE

    Since 1996, the Company has successively developed five generations of dilute phasedifferential pneumatic systems (DPT). The first application of Pneumatic Systems used toprocess Low Rank Lignitic Coal began in 1997 on a project with the electric utility, PacificCorp toupgrade high moisture lignite coals from Australias Hazlewood and Morwell seams. Later,PacificCorp successfully used the Pneumatic System to upgrade Wyoming Centralia lignite coal.Use of this Pneumatic Acceleration System removes moisture mechanically rather than usingsystems that require heat to evaporate moisture from the raw material. In production, thematerials are passed through the accelerator where carbon and water are separated by usinglow pressure high volume air exchange injected into the product which separates the twomaterials in structural form rather than using the eutectic phase change of water to steam toreduce moisture and increase calorific value. The end result is a dry coal product which issuitable for further processing. Product particle size is dependent on several interactive physicalprocesses but as a rule the particle size becomes smaller as more processing is used to removewater.

    These companies believed that developing synthetic fuel from coal fines was its best bet forcommercializing this technology. One reason for this strategy was the fact that it enabled thecompany to take advantage of significant tax benefits. After two Arab oil embargos in a singledecade, The US Congress created a federal synthetic fuels tax credit (Section 29) in 1979 topromote alternative energy production within the United States.

    For about 10 years, these Coal Processing Plants were installed and operated to removemoisture, ash and sulphur. These plants where constructed at mine sites and directly at powerplants to produce agglomerate coal briquettes for consumption by some of the largest electricpower producers in the United States . The companies involved in the development of theseplants, Covall, Headwaters and Terra Systems built over 30 coal drying plants and coalbriquettes plants for Power Plants . Headwaters' share price rose 383 percent during the 2001calendar year, reported the Salt Lake Tribune,making it the best-performing stock among Utah'spublicly held companies as a direct result of this programme .

    The Synthetic Fuel Tax Credit Programme (known as Tax Credit Section 29) in US that began in1998 was discontinued in 2007, and all the plants were idled and subsequently dismantled asscrap steel salvage. Without the aid of the tax credit, it was no longer commercially viable to usean agglomerated coal product due to the fact that ROM (Run-Of-Mine) coal in the US is veryin-expensive. Economic pressure on coal is further exacerbated by increased production ofMarcellas and also because of the massive availability of natural gas , which is a cleanerburning fuel with a substantially lower price .

  • AGGLOMERATION

    Our engineers have spent nearly a decade successfully developing our agglomeration processes,which recombines small particles of coal (coal fines) into briquette or pellet fuel which can beused in the same manner as the parent coal to power coal fired steam electric generationstations.

    The refined fuel, GeoMax Coal is produced using carefully formulated binders that will notdamage the boiler or its coal handling equipment. The binders used in our agglomerationprocesses are the result of over a decade of experimentation and successful commercialapplication by 28 US power companies.

    A NEW FUEL

    It was quite difficult (in the beginning) to get the electrical power utilities comfortable with theidea of introducing a processed fuel that contained relatively unknown binders into commercialboilers. Sophisticated demonstration of the attributes of these finished fuels in a 5 megawattinstrumented test boiler showed that the processed fuel performed as well as the parent coal fromwhich it was made. In some cases the processed fuel proved to be a more stable fuel than theparent coal. In the end, millions of tons of agglomerated fuel were burned by US powercompanies over a 12 year period with no major issues reported.

    During this development period, the engineering staff successfully managed to light a new way ofrelating to coal fuel production. Not only is it sufficient to dry mined coal, processing has to takeinto consideration each of the major attributes by which coal is graded. By comparing the rawcoal structure to the GeoMax Coal finished product specifications, sub-structures in the productunder manufacture can be manipulated to produce a consistent refined coal fuel which does notchange significantly from batch to batch. Additionally, a specific set of attributes may be specified(by the customer) before the GeoMax Coal is produced.

  • APPLICATION IN INDONESIA

    In Indonesia, the Pneumatic Accelerator System, sub-structure formulation and agglomerationprocesses will be combined into a unique system that will produce GeoMax Coal. Starting withhigh moisture (35-50%), low calorific value coal, refined GeoMax Coal will be produced in modernfacilities in commercial quantities.In recent testing, an LRC with a moisture content of 52% and a calorific value of 3,056 KC/Kg wasused as a processing material to produce GeoMax Coal with a moisture content of 8.02% and acalorific value of 6,488 KC/Kg.

    RECENT MILESTONES

    1997-2007

    Twenty-eight Syn-fuel plants are built using agglomeration technology developed by ourengineers. The fuel was used by power plants throughout the US to boost the quality of theirboiler feedstock.

    1997-2011Two PAS separation systems where constructed, predecessors to our GeoMax system.

    Site Licensing Agreements will be issued to Asia Pacific Resources & Mining Pte Ltd (APRM)our partner for Total Mine Development to build Coal Processing Plants in Asia.

    To quickly develop market awareness of GeoMax Coal and GeoAsia, we will continue to usewell-connected third parties to facilitate meetings with top power, cement and steel companiesin all Asian markets. In our experience, such third parties are able to quickly arrange meetingswith key decision makers; they understand the corporate cultures and priorities of thecompanies we meet; they provide political support; and thereby save us time, effort andfrustration as we define our working relationship with these companies. So the decision wasmade to grant Site Licensing Agreements will be issued to Asia Pacific Resources & Mining(APRM) our partner for Total Mine Development to build Coal Processing Plants in Asia.

  • Existing Power Plant Modification

    GeoAsia proposes to apply its proprietary GeoMax Kcal+ coal drying process, to arecently commissioned electric power generation station which is owned by PT PLN(Persero). The power station that is being investigated for suitability is the relativelynewly installed PTLU Tarahan facility. This station, commissioned in 2012, is situatednear Lampung South Sumatra Indonesia.

    From an engineering perspective, our primary concern is to facilitate the installation ofour equipment, with minimal interruption to the current operations of the station. This willbe accomplished by locating our coal drying equipment in proximity to the CoalPulverizing Equipment.

    As shown in the basic sketch below, GeoAsia will re-engineer the area between items#1 and #4. The ideal footprint addition is anticipated to be approximately 60 ft. (18.288meters) by 80 ft.(24.384 meters). This configuration may be compacted thru verticalstacking.

A pulverizer is a device forgrinding coal for combustion in a furnace in a power plant.

    Types of Pulverizers

    Ball and Tube Mill

    Ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to threediameters in length, containing a charge of tumbling or cascading steel balls, pebbles,or rods.Tube mill is a revolving cylinder of up to five diameters in length used for finepulverization of ore, rock, and other such materials; the material, mixed with water, isfed into the chamber from one end, and passes out the other end as slime.

    Ring and Ball

    This type consists of two rings separated by a series of large balls. The lower ringrotates, while the upper ring presses down on the balls via a set of spring and adjusterassemblies. Coal is introduced into the center or side of the pulverizer and is groundinto powder, as the lower ring rotates causing the balls to orbit between the upper andlower rings. The coal is carried out of the mill by the flow of air moving through it. Thesize of the coal particles released from the grinding section of the mill is determined bya classifier separator. These mills are typically produced by B&W (Babcock and Wilcox).

    Boiler : Pulverized coal is drafted or injected into boiler where it is ignited. Thiscombustion process heats water or other is heated and circulated until the water isturned in to steam at the pressures required by the Steam Turbine Manufacturer.

    Coal is burned inside the combustion chamber of boiler. The products of combustionare primarily Hydrogen and Carbon based coal gases and particulate of non-combustedelements. These gases which are at high temperature vaporize the water inside theboiler to steam. Some times this steam is further heated in a super-heater as the higherthe steam pressure and temperature the greater efficiency the steam turbine will have inconverting the heat in steam in to mechanical work. This steam at high pressure andtemperature is used directly as a heating medium, or as the working fluid in a primemover to convert thermal energy to mechanical work. This mechanical energy is thenconverted into mechanical energy (rotary motion) which is coupled to an electrical

  • current generator. Although other fluids are sometimes used for these purposes,demineralized water is by far the most common, because of its economy and its suitablethermodynamic characteristics.In point instant, the TARAHAN system is manufactured by JINAN BOILER GROUP CO.,LTD. Shandong , China .http://www.jnboiler.com/en/index.aspx?lanmuid=71&sublanmuid=681Of particular interest to our engineers, is the configuration and specifications of thepulverized coal transportation system between the pulverizer and the combustion inletof the boiler train. As the Chief Technology Officer of GeoAsia, I would intend to workwith plant operations and engineering and purpose that positive positioning gatedampers be installed in the coal fines transport system, which would allow metering ofthe coal feed going into the steam generator. By design, the GeoAsia system requirescoal feedstock similar to the coal which is presently being fired at PTLU Tarahan. In anover simplified description of the GeoAsia system, our proprietary technology removesentrained water from a eutectic composite material by dilute phase differentialpneumatic system fed by low humidity air stream.In previous operations, we have been able to reduce moisture from Low Rank LigniticCoal in Indonesia from levels around 50%, down to a total moisture of 8%.Our operational goal is to design a parallel system where the dried coal can bemetered into the boiler along with your existing wet coal feed. At the same time, wewill proportionally reduce the existing wet coal so that the control room operators cankeep the flame path at its optimum efficiency without losing flame. Because the lowermoisture of the GeoMAX, we would anticipate that the fire-stream can be maintained atthe desired point of going over the crown into the economizer.In using the GeoMax dried coal product, we predict that the emissions will be reducedfrom the stack, the flow rate and efficiency will increase and the operating costs willdecrease.

    Overview

    The Proprietary LRC Processing System (GEOMAX LRC PROCESSING SYSTEM) Technology comprises a gas linear particle accelerator that transports and processes bulk material at high velocity in a particle isolated state, using air as the medium of movement.

    The system is a unique gas linear particle accelerator, which permits a uniform dispersal of materials at a high degree of particle isolation. The dry process method utilizes air (or other gases) as the medium of movement, carrying bulk materials at high velocity but low pressure. The system can transport almost any particle, for any duration of time, at any temperature, and at any velocity/density ratio (a key principle in fluid dynamics). The combination of the system's ability to isolate particles and to transport them at high (and varying) velocities permits bulk materials to be accelerated, stratified, and electrified (the particles absorb electrical properties). As a result, the system can process industrial bulk materials in a variety of ways, including: separating, pulverizing, drying, classifying, mixing, forming, transporting and trans loading. These processes are seen as broadly applicable to handling coal, coal ash, rice, grains, precious metals and waste materials, to name just a few. The system has six basic components:

    1. Pneumatic injector feed system 2. Motive force delivery package 3. Transmission lines to the exclusive accelerator assembly 4. Accelerator assembly 5. Product lines through which bulk materials are transported 6. Computer operated controls 7.

    GeoAsia Proprietary system utilizes slow-moving laminar gas to transport bulk materials through a carrying duct. The gas flows at high velocity, but at low pressures and temperatures. Differential velocities create a "boundary" layer of air next to the outside wall of the conduit pipe and the center flow of the material much like "currents in a river". The main central current is faster than the outside current, thus protecting the bulk material from the walls of the pipe. When the gas in the pipe is accelerated, it creates an optimal differential environment, in which velocity controls density. The faster velocity in the center of the duct and the differential velocity with the boundary layer, puts the particles into a "high-spin state". This "spin state" provides a mechanism to dry the material while it is being transported as well as creating electro-magnetic, electro-static and electro-plasmatic properties if so desired.

    In this accelerated state, the particles can be reduced in size by: 1.) colliding the particles with each other as they move irregularly through the duct at high velocity or

  • 4

    2) directing

    the particles to strike an ablative plate - the particle size determined by the impact velocity which can be finitely adjusted by the system's unique accelerator.

    Functionally, GeoAsia unique system can perform a variety of physical procedures. These primarily include:

    1. Isolating particles 2. Pulverizing (down to very fine pharmaceutical compound size) 3. Drying 4. Classifying/Sorting 5. Mixing 6. Forming (pelletizing, briquetting, etc.) 7. Transporting

    8. Trans loading (transferring from one mode of transportation to another) Economic benefits from utilizing the system include:

    1. Higher unit prices of end products through drying, classifying, upgrading, beneficiating, concentrating, etc.

    2. Lower unit costs of production through greater efficiency, use of air as a medium of movement rather than water, systems ability to perform multiple task at the same time, no requirement for chemical additives and lower maintenance costs.

    The GEOMAX LRC PROCESSING SYSTEM Technology is applicable to both organic and inorganic materials. Virtually all bulk materials used in basic industries can use the technology, such as:

    Agriculture

    Used in the drying of grains, sugar, etc. Soil reconditioning by restoring depleted trace elements.

    Ronald L. Frank, Executive Vice President of Ecology and Environment states: "We are impressed with the potential applicability of GeoAsia LRC system to a wide variety of environmental issues. In particular, we believe the ability of GeoAsia system to operate without water will become an increasingly attractive attribute in the worldwide marketplace. GeoAsia anticipates it will share in the economic returns from the use of its technology through fees, royalties and/or profit sharing.
