硫酸吸氨法回收氨
ammonia recovery process
liusuanxi，an fa huishou an硫酸吸氨法回收氨(ammonia reeovery bysemi一direct process)焦炉煤气回收氛的一类方法。它以硫酸为吸收液，回收煤气中的氨，同时制成硫酸按。最早开发的方法是直接法，该法用硫酸在焦炉煤气初冷前直接吸收煤气中的氨，对煤焦油质量有不利影响，故被半直接法所取代。半直接法将吸氨设备移到煤气初冷之后，克服了直接法的缺点。该法将焦炉煤气初冷过程中产生的含氨冷凝液进行蒸氨处理，蒸馏出的氨引入初冷的煤气一并用硫酸吸收。半直接法分为饱和器法和酸洗塔法两种。饱和器法是一种传统的半直接法，已有百年历史，产品为粉状结晶硫酸钱。酸洗塔法是20世纪40年代开发的，已为各国采用。产品为大颗粒结晶硫酸馁。硫酸吸氨法的优点是流程短，设备少;缺点是硫酸耗用量大，lt产品耗用0.75t硫酸，成本较高。 (徐一)
