Coal Processing PlantIn accordance with Gazette Notification GSR 560(E) amp; 378 (E) issued by Ministry of Environment and Forests, Govt. of India dated September#226; 97 and June#226; 98 respectively, Thermal Power Plant must make use of coal with ash content less than 34%.
For providing heat from coal there exist the routes via electricity production, via gasification and via hydrogenation, and of burning the coal gas or the coal oil at the producers end. To compare these different routes, both efficiency and specific emissions related to the production of useful heat energy have to be determined for the individual routes.
Coal provides numerous raw materials like benozle, coal tar, sulphate of ammonia, creosote, etc. to chemical industries. Coal is mostly used as a source of energy is most of the industries. Gasification and Liquefaction. Coal can be turned into a synthetic gas which a mixture of carbon monoxide and hydrogen.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

China is rich in coal resource, which is vital for energy security in this country. In early 21st century, the coal chemical industry in China will be oriented to the development of high efficiency, safety, cleanliness, and optimum utilization.
Fire ranks high on the list of costly risks to chemical plants, according to FM Global, a Johnston, based business insurer. The risk of fire often stems from the chemical processes themselves, which frequently involve volatile and flammable Full Story
Coal gasification Wikipedia
Coal mined from the Talcher region of Odisha, India is known to be highash, surfaceoxidized, and noncoking in nature. It is quite challenging to beneficiate such lowgrade coal by physical or physicochemical processes due to its oxidized nature and the presence of complex ash forming mineral matter in its matrix. Chemical beneficiation is one of the alternative process to such problems.
Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.
Coal gasification is the process of producing syngasa mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as quot;town gasquot;.Coal gas is combustible and was used for heating and municipal lighting, before
Coal is one of the primary sources of energy, accounting for about 67% of the total energy consumption in the country. India has some of the largest reserves of coal in the world. Indian coal has high ash content and low calorific value. However, with the present rate of around
2 #0183;#32;The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7)
