Abstract:Different to IGCC, gas turbine can be fired both by coal gasification syngas and purge gas released from methanol synthesis process. But these two kinds of gases are of different nature, such as composition, flow, pressure and temperature. So power output is related with flow of coal gas and purge gas when methanol production and total amount of coal gas are fixed. With process modeling, simulation and analysis, a unique correlation between power output, methanol synthesis, proportion of coal gas used as gas turbine fuel and recirculation rate of purge gas can be revealed. Besides this, the net power generation efficiency of coproduction plant is compared with a single-product (power) one, from which is shown that thermal efficiency is able to be enhanced two percentage due to power and methanol coproduction.
Keywords:coproduction  plant efficiency  heat to power output  methanol synthesis
