摘要: 将合成氨生产与尿素生产联合起来(简称“联尿”)是尿素生产的一个发展趋势。本文介绍用中压变换气气提“联尿”的方法,并经工业化运转,证明本流程在工艺上与经济上都是可行的,适合于我国中小型合成氨厂的改造。文内对气提塔的结构进行了探讨,并指出本流程中存在的问题与改进途径。
Abstract: The integration of urea and ammonia process is a tendency for the development of urea production. In this paper, the development work on integrated urea-ammonia process by stripping with converted gas at medium-pressure is described and this process has been proved in an industrial plant. The result of techno-economic feasibility study has shown it to be viable. A detailed review is also given on the choice of the stripping tower - the critical equipment of the process. Problems encountered are discussed, and the direction of improvement is presented.
