Coal Syngas

 Coal Mining Started in Assam in 1870.
 N.E. Region’s Coal reserve is 0.94 BT i.e., only 0.37%
share of India’s total reserve.
 Coal can be found in the States of Assam, Arunachal
Pradesh, Meghalaya & Nagaland.
 Are mostly sub-bituminous, semi anthracite Coal with high
calorific value between 6500-7500 k.cal/kg.
 Except for Coking units there are no Coal - Value Addition
based Industries in N.E.India.
 Coal is extensively used as Fuel by Cement Plants, Tea
Gardens, Steel Rolling Mills.


 Diverse qualities per location & strata.
 Most Coals contain very high Sulphur.
 Usually the Coals are high in Caking index.
 Most are unsuitable for Metallurgical applications.
 Poor Mining Practices generates high volume of Coal Dust,
Fines & Slurry.
 Inconsistent quality and sizes provides poor burning efficiency
to consumers.
 Most Consumers are located far from the mining areas.


 Gasification is a process that convert solid feedstock like coal
or biomass into a combustible gas.
 Coal Gas is also called as Syngas or Synthetic Gas.
 Syngas can be burned cleanly with little pollution.
 Basic Syngas consists of Hydrogen, Carbon-monoxide and
Nitrogen with trace element of other gases.
 Modern Gasification Systems produce a Syngas at par with
natural gas called “Synthetic Natural Gas” or SNG.
 There are 178 operating gasification plants and 902
Gasification companies worldwide.


 Syngas is more efficient and environmentally much cleaner than
direct combustion of the original fuel.
 It can be compressed, piped and transported to the end user.
 Syngas may be burned directly in Burners, Furnaces, Boilers,
Turbines, IC engines.
 It is also used to produce Methanol, Hydrogen and Ammonia or
even converted into liquid Fuels.
 The two main waste products, Coal Tar & Ash are raw-materials
for the Chemical and Cement Industry.
 Pricing of Coal-SNG is dependent on Coal which is lower and
more stable than the fluctuating Natural Gas prices.
 Even low-grade grade Coal like Lignite can be Gasified.


 LOW BTU GAS 150-300 BTU/ft3: Basic Syngas produced by air
fed Gasifier which contains 35-50% nitrogen, but suffices as
normal industrial heating fuel.

 MEDIUM BTU GAS 300-550 BTU/ft3: Higher grade Syngas
produced by Oxygen fed Gasifier which requires a dedicated
oxygen Plant. It adds Nitrogen and other gases to the saleable
product portfolio.

 HIGH BTU SNG 1000-1400 BTU/ft3 : Gas at par or higher than
natural gas. Requires gas de-sulphurising unit and a catalytic
unit, called a “Shift-reactor” to upgrade the Gas.


• Have complete utilization of coal.
• Undertake product value-addition on site.
• Receive higher prices than Coal.
• Produce multiple products like SNG for Consumers, Fly
Ash for Cement Plants, Sulphur for Chemical plants etc.
• Reduce Transportation movement & loading costs.
• Reduce Pollution.
• Coal Gas is a direct competitor to Natural Gas hence it
has an established market and consumer base.


• Have complete utilization of Fuel.
• Consistent fuel quality and energy density.
• No waste products like Ash and Unburned Coal.
• Less manpower needed.
• Less maintenance, cleaning and downtime.
• Economy almost at par with raw coal burning.
• Reduce Transportation movement & un-loading costs.
• Reduced Atmosperic, ground and Water Pollution.


 Coal Syngas is most widely used worldwide on industrial scales
to generate electricity.
 Worldwide gasification capacity is projected to grow 70 percent
by 2015, with 80 percent of the growth occurring in Asia.
 China has 80 Coal-SNG units under planning & construction.
 In 2013 Ukraine in setting up 5 SNG plants at the cost of 35
billion USD.
 In India Coal Gasification has only been adopted by several
Industries like Steel, Ceramics etc., for captive Consumption.
 IGCC or “Integrated Gasifier Combined Cycle,” ,is the latest and
cleanest system of Generating Electricity from Coal.
 GE, Siemens, Lurgi, British Gas Ltd provide Coal Gasification
Technology.


 Synthetic Natural Gas – Industrial & Domestic Fuel.
 Electricity – via Gas based Generator, Turbines or IGCC .
 Fly Ash - Raw material for Cement Plants.
 Ammonium sulfate - Fertilizer.
 Anhydrous ammonia - Fertilizer.
 Dephenolized cresylic acid – Raw material for Pesticides.
 Phenol – Industrial chemical.
 Sulphur – Raw Material for medical and Chemical Industry.
 Methanol
 Hydrogen
