回收草铵磷生产过程废溶剂的工艺设计及优化

Optimized Design for Recycling Waste Solvent Generated by the Process of Producing Glufosinate

针对草铵磷生产过程产生的废溶剂,设计了3种工艺流程用以回收其中的四氢呋喃、甲基亚磷酸二乙酯、亚磷酸三乙酯、混合三甲苯等有用组分.分别对3种工艺路线进行实验计算,以产品的纯度、收率、能耗及设备造价为指标,考察分析确定最佳的工艺方案,为废溶剂的资源化再生利用提供可行方案.

Three kinds of processes are designed to recycle waste solvent which consists of tetrahydrofuran, ethyl methyl phosphite, phosphorous ether and trimethylbenzene generated from the process of producing glufosinate. Taking product purity, yields, energy and equipment cost as indexes, the three kinds of processes routes are experimented and calculat- ed respectively to analyze and obtain an optimum process scheme to provide a feasible solution to recycling this waste solvent into resources.
