Can IGCC power generation be carried out using methanol-derived flue gas? This post was last edited by mountain16 on 2009-4-10 13:34.]
A low calorific value is not a problem; it can be mixed with other raw gas streams, such as coke oven gas or coal gas! Using a larger amount is not a problem, but the bleed gas can only be used as an auxiliary fuel gas; the main fuel gas should still be used as per the design.
Adding an appropriate amount of methanol synthesis off-gas to gas can be used for IGCC power generation
Is the calorific value of methanol off-gas low? The calorific value of the methanol off-gas in one factory I saw was around ten-odd MJ, which is likely higher than that of the syngas produced in the gasification process.
Synthesized flaring gas is acceptable, as long as a gas turbine with a low calorific value is used; for details, one can refer to the methanol IGCC co-generation demonstration plant operated by Yankuang Group Guohong.
