帝国化学公司(ICI)开发了一种新的,以天然气为原科的制氨法——AMV法,该法有如下特点: 氨的合成压力为86kg/cm~2,转化率达14％; 原料气中的氢氮比较低,约为2.5; 允许原科气有较高的残余甲烷量,可在1～2％之间; 第一转化器的体积仅为惯用的一半,出口温度较低;

Imperial Chemical Company (ICI) has developed a new, ammonia-based ammonia-AMV process that uses natural gas as its base. This process has the following characteristics: ammonia synthesis pressure of 86 kg / cm ~ 2 and conversion of 14%; The raw material gas has a relatively low ratio of hydrogen to nitrogen of about 2.5; allowing the primary gas to have a higher residual methane content of between 1 and 2%; the volume of the first converter is only half that of the conventional one and the outlet temperature is lower ;
