目前,国内合成氨厂,在合成氨催化剂升温还原时,对其水汽浓度的分析,一般都采用电石称重法或乙炔比色法。上述方法,手续繁琐,时间长(每次1—2小时),不能及时给出数据,影响因素较多,不易做准。在我厂试车生产过程中,我们遵照毛主席“人类总得不断地总结经验,有所发 At present, the domestic ammonia plant, in the synthesis of ammonia catalyst temperature reduction, the water vapor concentration analysis, are generally used calcium carbide weighing method or acetylene colorimetric method. The above method, tedious procedures, a long time (1-2 hours each time), can not be given in time, more influencing factors, not easy to do prospective. In our factory test production process, we follow Chairman Mao "Man always have to sum up experience, have issued
