大型渣油水煤浆氨厂回收液氮洗CO尾气联产4万吨／年甲醇的经济性

Economies of oil-based and water-coal slurry-based large ammonia plants to coproduce 40, 000 t/a methanol by reclaimating CO from tail gas from liquid nitrogen washing process

从液氮洗尾气中回收ＣＯ再配入粗Ｈ_２，在等压下合成４万吨／年甲醇采用离心式循环机，可在几个大厂结合具体情况进行。

Adding crude hydrogen to recovered COfrom tail gas from liquid nitrogen washinS process to makesynthetic methanol at constant pressure with the capacityof 40, 000 t/a using centrifugal circulator is the essential ofthe technology. This technology may be realized at somelarSe plants in connection with their specific conditions.
