摘要
结合鲁西化工集团股份有限公司现有粉煤加压气化装置的运行情况，对停运固定床造气炉后的原料气来源进行探究，提出了将低温甲醇洗工序的净化气、PSA工序的解析气、CO膜分离工序的渗透气送至氮氢气压缩机的改造方案。通过对原料气路线的改造，既减少设备闲置、提高设备利用率，又提高生产效率。
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.
