中文摘要	裂解气压缩机作为乙烯装置的核心设备,其顺利启动对乙烯装置开车过程有着重要影响。传统的乙烯装置开车流程大多使用裂解气启动压缩机,近年来已经逐步被氮气、天然气和混合烃等开车工质取代。由于无法利用实际压缩机装置进行测试,因此化工模拟技术成为了解决上述问题的重要工具。本文根据"稳态-动态-开车"的研究方法,建立了某裂解气压缩机的稳态模拟模型,确定了氮气、混合烃和裂解气运行时的稳态运行参数。之后,将稳态模型转换为动态模型,通过动态模拟验证了各工况之间转换过程的安全性和可行性。; The crack gas compressors are the core equipment of the ethylene plant,whose smooth start plays an important role in the whole plant's start-up process.In traditional start-up process,the crack gas compressors start with the crack gas,which is replaced by other working mediums in recent years,such as nitrogen,natural gas or mixed hydrocarbon.Due to the impossibility to test on the equipment,the chemical engineering simulation technology has become the important tool to solve these problems.In this paper,according to the "steady-state/dynamic/start-up" method,a steady-state simulation model of crack gas compressors is built,and the steady-state operation parameters of the crack gas,nitrogen and mixed hydrocarbon were determined.Then,the steady-state model was converted to the dynamic model.At last,the safety and feasibility of transformation process between various working conditions were verified.
