The coal gasification process (CGP) converts highash coal into synthesis gas, or syngas. "It is the first plant of its kind in the world where syngas is used in making DRI.
The total installed capacity of coalbased DRI plants is Mt while that of gasbased DRI plants is Mt, with two plants using gasification route (Syngas and COREX gas) and three plants using natural gas route supplemented by COREX/ coke oven gas.
The main technology being used is coal gasification instead of burning the fossil fuel, it is chemically transformed into synthetic natural gas (SNG). The process is decades old, but recent ...
