现有合成氨厂建设8万吨/年硫酸钾及4万吨/年纯碱装置的可行性

The feasibility of building the 80 000 t/a potassium sulfate and 40 000 t/a soda ash plants on the ground of an existing ammonia plant

本文试图论述现有合成氨厂改变产品结构,采取以生产化肥为主,联产化工产品。通过对钾芒硝法工艺及联碱工艺技术路线的选择,技术经济分析,以期提高化肥厂的经济效益。

The paper attempts to deal with how an ammonia plant be able to coproduce chemicals, while maintaining the fertilizer as main product, through the transformation of structure of products. By choosing the technical routes of potassium sulfate process and integrated process of soda ash production,the better economical benefits can be expected.
