away from NPLCT. The coaltomethanol process was simulated using ChemCad to solve chemical and energy problems. Based on heat material balance simulation results, the plant requires coal of million tons/year as a raw material. Air Product technology was chosen for coal gasification and Davy Technology for methanol synthesis.

power generation from Integrated Gasification Combined Cycle (IGCC) plant. There are three main types of coal gasifiers namely, moving (also known as fixed) bed, fluidised bed and entrained flow. In a moving bed gasifier, the coal is fed through the top of the gasifier and the oxygen and steam usually from the bottom.

The coal gasification process results in a CO 2 stream that is very dry and about 96 percent pure, so it requires no further processing. This is in contrast to CO 2 from power plant flue gas, which is wet and diluted with nitrogen and oxygen, and requires further processing. The Synfuels Plant's gasification operation draws worldwide attention.

In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

The feedstock for the plants is subbituminous coal supplied by Mining, a sister company of Synfuels. Natural gas is also used as a supplemental feedstock. A proprietary ironbased FT process is used to convert the synthesis gas (syngas) produced by the gasifiers to gasoline, light olefins (alkenes), and a variety of other products.
