摘要
从液氮洗尾气中回收ＣＯ再配入粗Ｈ_２，在等压下合成４万ｔ／ａ甲醇，采用离心式循环机，设备技术先进，流程短、设备少、能耗低、投资省、效益高，可在９个大厂推广。
The 40kt/a methanol is synthesized under constant pressure by recovering CO in tail gas from liquid nitrogen washing section and then adding crude H_2.The process using centrifuge type recycling compressor is of the merit of advanced equipments and technology, short flowsheet,less equipment items,low energy consumption,invest saving and high profit,it can be realized in 9 large scale ammonia plants.
