46万吨/年煤基烯烃装置开工氮气压缩机组的技术选型分析

摘要

针对大唐多伦煤化工46万吨/年煤基烯烃装置shell气化炉开工用氮气压缩机，对前后选用的往复式和离心式两种型式的压缩机的平面布置、压缩机自身的性能、运行的稳定性以及驱动机的参数选择进行对比与分析，确定最优的机型方案，确保机组平稳运行，保证气化炉的正常开车。%The comparison and analysis of reciprocating and centrifugal compressors in terms of layout, performance, operating stability and drive parameters are implemented in view of Nitrogen compressor for Shel Gasifier at 460,000 t/a coal-based olefin unit in Duolun Coal Chemicals, Datang. The optimal model is set up on the basis of the results so as to ensure the stable operation of the compressor and gasifier.
