摘要：将硫酸生产中的尾吸过程与磷铵生产过程结合，使原尾吸的副产品亚硫酸铵转变为磷铵和二氧化硫，含二氧化硫８ ％ ～９ ％ 的气体返回硫酸生产系统。该工艺技术可行，投资少，产品结构合理，原料利用率高，对国内大多数磷肥厂均适用。
A new process combines the tail gas absorption process of sulphuric acid production with ammonium phosphate production and changes bypass product ammonium sulphite to ammonium phosphate and sulphur dioxide containing gas, which with 8%～9% SO 2 is returned to sulphuric acid production It′s provn that the technology is practicable and has reasonable product,high raw material utilization ratio and low investment Therefore, it could be applied to most of the phosphate fertilizer factories in China
