Abstract: Combined with the operation situation of the existing pulverized coal pressurized gasification unit of Luxi Chemical Group Co.,Ltd.,the disadvantages of batch fixed-bed gasification technology are analyzed,and the source of raw material gas after stopping the fixed-bed gasifier is explored.A renovation scheme is proposed for raw material gas route by sending the purified gas after the low-temperature methanol washing section,the desorption gas after PSA section,and the permeate gas after CO membrane separation section to the nitrogen-hydrogen compressor.After renovating the raw material route,the idle equipment is reduced,both the equipment utilization and the production efficiency are improved.
