A compressor calculation module was developed based on domestic chemical process simulation software.Firstly,five mathematical models of the compressor and the solution steps were established,then the compressor calculation module was developed by using object-oriented C++language and COM middleware technology,and finally the accuracy of module calculation was checked by using the actual data of ethylene cracking unit.The results showed that the average relative deviations(ARD)of compressor power were 0.43％,and the ARD of compressor outlet material temperature and density were 0.12％and 0.02％,respectively.The simulation results match well with the actual industrial values,which indicated that the established compressor calculation module was stable and reliable,and will play an important guiding role in the simulation calculation of gas compression processes in chemical processes.
