一、前 言 合成氨工艺流程长,工艺设备复杂,对气体质量的要求比较严格。我厂工艺流程,是从压缩机五级加压至125～135公斤/厘米～2后送入铜洗,采用醋酸铜氨液洗除气体中部份二氧化碳和一氧化碳,再进入六级压缩至320～330公斤/厘米～2送至合成塔。如果气体中含油,会严重影响醋酸铜氨液洗涤效率,对合成氨触媒中毒也较敏感。因此,气体中少油或无油对合成氨来说是极为有益的。
I. Introduction Ammonia process long, complex process equipment, the gas quality requirements are more stringent. I plant process is pressurized from five compressors to 125 ~ 135 kg / cm ~ 2 into the copper wash, the use of copper acetate ammonia solution to remove some of the carbon dioxide and carbon monoxide, and then into the six-stage compression to 320 ~ 330 kg / cm ~ 2 to the synthesis tower. If the gas oil, will seriously affect the efficiency of copper acetate ammonia washing efficiency, ammonia poisoning is also more sensitive to synthetic catalyst. Therefore, less or no oil in the gas is extremely beneficial to ammonia synthesis.
