  • Coal gasification Wikipedia

    Coal gasification is the process of producing syngas–a 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.

    Gasification Wikipedia

    Gasification is a process that converts organic- or fossil fuel-based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.

    First, coal is processed into coal gas in the gasifier, where oxygen is used as the gasification agent. Coal gas undergoes desulfurization and de-dusting treatment in the gas clean-up unit to comply with the standards for gas turbine fuel and exhaust gas. The “cleaned gas” is supplied to the GTCC facility.

    By mixing coal with steam and oxygen, in a high-temperature and pressure gasifier, a gas will result. A scrubbing and purification process will then refine the organic matter into high BTU gas and by-products. It is the use of these by-products, as well as the gas, that insures a waste free and feasible process.
