Coal has better absorption capacity of CO2 and it will result in more desorption of CBM. With limited reserve potentiality of petroleum & natural gas, eco-conservation restriction on hydel project, improvement in technology for harnessing renewable energy and geo-political perception of nuclear power, it is becoming increasingly evident that coal will continue to occupy centre-stage of India’s energy scenario. Welcome to Sleepy Classes. What is coal gasification, the project at Talcher? Urea is currently produced using pooled natural gas, which comprises of both domestic natural gas and imported LNG. • Methane or natural gas extracted from coal gasification can be converted into LNG for direct use as fuel in transport sector. What is Underground coal gasification? Coal washing is one of the practices being promoted as a measure to encourage clean coal technologies and Coal India Limited (CIL) is in the process of setting up sixteen new coal washeries with a total throughput capacity of 92.1 million tonnes per year through global tendering process. Natural gas based methanol plants are of small size. • Underground coal gasification (UCG) is an industrial process which converts coal into product gas (predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide) • UCG is an in-situ gasification process carried out in non-mined coal seams using injection of oxidants, and bringing the product gas to surface through production wells drilled from the surface. Top Quality GS Coaching. India’s CBM potential is estimated at 450 tcf. Only a fraction of C is burned for generation of heat. • Even at shallower depths (< 500m), UCG can be more economical than conventional mining. • Bye products of significant commercial value will be hydrocarbons, phenols, anhydrous NH3 and clean water. It is important to spell out specific criteria that must be met before UCG may be considered for a large commercial application, especially given complex nature of UCG technology that combines geotechnical, chemical, and mining aspects. coal gasification process aUtoMation T he United States has enough coal to provide energy for the next 200 years with a recoverable reserve base of nearly 475 billion tons. Syngas from UCG can be used as a feed stock for CTL for production of clean synthetic liquid fuels using Fischer Tropsch process. An oxidant, usually air, flows through an injection well and into a cavity in a coal seam. ; The government had announced that it would remove the government monopoly on coal mining by introducing commercial mining on a revenue sharing basis. • Inconsistent supply of syngas: Both the flow and heating value of gas will vary. The oxygen and water within the coal seam react with the coal to produce syngas, which is withdrawn through a production well. • Possibilities of using CO2 from the gas for enhanced oil recovery exist. • UCG produces insignificant surface disruption and brings no solid waste to the surface. LTD is the parent company of CIVILSDAILY IAS. The unit secured orders for key gasification equipment from Wuhan Engineering, China against stiff Chinese competition for Talcher Fertilizer, which is the first-of-its-kind coal gasification project in India. Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). Historically, coal was gasified to produce coal gas, also known as "town gas". Pyrolysis, the chemical decomposition of organic (carbon-based) materials through the application of heat.Pyrolysis, which is also the first step in gasification and combustion, occurs in the absence or near absence of oxygen, and it is thus distinct from combustion (burning), which can take place only if sufficient oxygen is present. This gives Methane, Hydrogen, Carbon monoxide by combination of Coal, Water and oxygen. FREE. The decision is geared towards reducing India’s reliance on imports and helping the country meet its CoP-21 Paris Agreement commitments. This will help in meeting the energy demands. Transporting gas is a lot cheaper than transporting coal. The syngas can be used in a variety of applications such as in the production of electricity and making chemical products, such as fertilizers. • Economies of scale: Without economies of scale operation, the project will render uneconomical.
