中空纤维气态膜法回收稀氨水中氨制取硝酸铵的研究

The Research of Production of Ammonium Nitrate Making From Dilute Ammonia Liquor With Hollow Fiber Membrane

针对合甲醇的稀氨水，用中空纤维气态膜法回收氨制取硝酸铵，甲醇对回收氨及制取硝酸铵的过程无不良影响。聚丙烯中空纤维在料液中长期浸泡强度无明显降低，物理性能是稳定的。

Ammonia nitrate is made from ammonia liquor containing methanol with polypropylene hollow fiber membrane. Methanol is unremarkable influence to recover ammonia and to produce ammonia nitrate. The strength of polypropylene hollow fiber membrane that is soaked in the starting liquor is not descended and physical property of it is stable.
