突破难题“双甲工艺”诞生合成氨产业是现代工业的产物。然而,自实现工业化以来的一百余年时间里,其生产工艺三大过程中以煤为原料的原料气净化精制一直没有根本性的技术进步,国内外均沿用以清除为唯一目的的铜氨液洗涤法、深度低变甲烷化法或液氮洗涤法等。而这些方法都存在重 A breakthrough in the problem of “Double A Process” was born Ammonia industry is the product of modern industry. However, since the industrialization of more than 100 years since its production process of the three major processes using coal as the raw material purification has been no purification of raw materials, both at home and abroad are to remove the copper for the sole purpose of ammonia Liquid washing method, the depth of variable methanation or liquid nitrogen washing method. These methods are heavy
