‘18.30’工程压缩机技术分析与探讨

Technique Analysis and Discussion for “18.30" EngineeringComressrs

‘18.30’工程就是建成年生产能力达到18万吨合成氨、30万吨尿素的项目,项目中的关键设备为氮氢气压缩机及二氧化碳压缩机,压缩机选型正介于往复式压缩机和离心式压缩机之间,国内各设计院在八家立项的以煤为原料的中化肥厂‘18.30’工程初步设计中选何种类型的压缩机争论不休,本文从技术及经济的角度对此作了分析比较,并推荐采用往复式压缩机,以供参考。

is the project to produce 18 ton/ year synthetic ammonia and 30 ton/ year urea. The key equipment in the project are the compressor for the mixed gases of nitrogen and hydrogen and the compressor for carbon dioxide. Reciprocating compressor as well as centrifugal compressor can be selected for this project. The different opinions for the selection of the compressor existed in 8 medium scale fertilizer plants in which coal is used as the raw material. From the points of technology and cost, the analysis and comparison of using these two kinds of compressor were carried out. It is concluded that reciprocating pump is more appropriate.
