氨是由氮和氢在高温、高压和催化剂存在下化合而制成。将含碳原料(煤或石油气、焦炉气等)在造气炉中通入空气和蒸气制成原料气,然后精制为1:3的氨氢混合气、压缩,进入合成塔部分氮氢混合气化合成氨。氨主要用于制造氮肥,如尿素、硝酸铵、碳酸氢铵等,还可以用于制液氨(做致冷剂等),硝酸、铵盐和胺类等。
Ammonia is made from the combination of nitrogen and hydrogen in the presence of high temperatures, pressures and catalysts. The carbonaceous feedstock (coal or LPG, coke oven gas, etc.) is introduced into the gasifier into air and steam to make the feed gas, which is then refined into a 1: 3 mixture of ammonia and hydrogen, compressed, Mixed gasification ammonia. Ammonia is mainly used in the manufacture of nitrogen fertilizers, such as urea, ammonium nitrate, ammonium bicarbonate, etc., but also can be used for liquid ammonia (refrigerant, etc.), nitric acid, ammonium salts and amines.
