Process: Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas. This gas is then used instead of piped natural gas, methane and others for deriving energy. Insitu gasification of coal or Underground Coal Gasification (UCG) is the technique of converting coal into ...

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.

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coaltomethanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO2 from the gasification plant by implying process intensification. The base case and ...
