FGD ApplicationThe requirement for Flue Gas Desulphurisation (FGD):-

� In the combustion of coal, oil, waste and in the production of metals from ores, large amounts of SO2 are produced. SO2 can have a harmful effect on human health and damage to the natural environment. Lead to development of Flue Gas Desulphurisation technics, that removes SO2 from the flue gas prior to release to the atmosphere.

� In order to reduce SO2 emission, coal fired power stations across the world have been fitted, or are in the process of retrofitting SO2 scrubbers.

� Nearly all SO2 control methods works on the principle that alkali sorbent sprayed in the flue gas reacts with acidic in nature SO2, also with HCl and HF. Reaction products are captured in dust filters (Dr y FGD), precipitates from gypsum slurry in the sump (Wet FGD), or it is disposed after treatment to the sea (Sea Water FGD).

� The most commonly used sorbent in the desulphurisation process are: limestone, lime, hydrated lime.

What we do

In order to control FDG systems, these processes require monitoring throughout. SEPL offer a range of products that can monitor both input and output gases, flow & dust emissions reliably and accurately using the very latest technology.

FGD TechnologiesComplete dry systems (injecting dry sorbent, lime or bicarbonate)

� In a dry sorbent injection (DSI) process dry sorbent is injected to the flue gas stream. This reacts with SO2 and other acid gases which are captured downstream in dust filter.

� Due to low efficiency in capturing SO2 ranging from 50 to 70%, nowadays this process has a small share in FGD plants.

Semi-Dry :- Type 1-Spray Dryer Absorber (SDA with hydrated lime)

Type 2-Circulating Dry Scrubber (CDS/NID with hydrated lime)

� Semi-dry FGD are typically installed on smaller facilities, often being a good alternative to � Semi-dry FGD are typically installed on smaller facilities, often being a good alternative to Wet FGD on sites that are retrofitting FGD plants.

� In Semi-dry process, although water is added, gas is maintained above the saturation point (dew point). Typical DFGD operation temperatures are 15-20°C above dew point (70 to 75°C).

� Semi-dry FGDs are typically integrated with downstream fabric filter that collects reaction products in a dry form.

Wet Scrubbers :- Type 1-Lime or limestone slurry

Type 2-Sea water washing SWFGD

� Wet Lime Scrubbers are a predominant FGD process, typically installed on the large facilities where low quality high sulphur coal is used.

� In the wet absorbers, flue gas is sprayed with lime slurry. In the process gas is cooled below saturation temperature, resulting in high efficiency in capturing acid gases.

SEPL CEMS Extractive system

� By the working of high temperature sampling pump, flue gas passes sampling

probe (filter cartridge included), heat tracing pipe, ball valve, secondary

filter, then enters analysis mode and is discharged at last,

� The whole process is with above1200c heat tracing in case of any corrosion

and blocking caused. and blocking caused.

� To avoid filter cartridge being blocked by dust, system should periodically

close ball and control purge valve to provide pulse purging for probe.

� This analyzer supports automatic (zeroing and span calibration).Measurement

flow path closes when calibration is carrying out. Secondary filtration has

protection function to protect analysis module when probe is leaking and

temperature controller fails.

SEPL UV DOAS CEMS Principle

The analyzer adopts UV differential optical absorption spectroscopy (DOAS) which can precisely measure

concentrations of trace gases using absorption spectrum of gas component. The basic principle is to identify

gas molecule with the narrow-band of detected molecule.

EMERGING TRENDS & CHALLENGE FOR

FUTURE TO SOX/NOX MONITORING

� Norms in developing countries like India will next few

years adopt European/USEPA standards requiring very low

ranges of measurement thus posing challenges to NDIR &

equivalent technologies.equivalent technologies.

� Modern FGDS may call for accurate measurement of HCL

in very low ranges in addition to SOX giving rise to use of

LASER technologies like TDLAS, QCL ,Intraband Laser etc.
