Dynamic simulation has been finding extensive application in modeling and simulation of various chemical processes. With the availability of high speed computer it’s become customary to use Dynamic simulation to analyze various operating scenarios which not only include steady state scenarios but also dynamic situations like startup, planned shutdown and emergency shutdown. In this present work, various methods used to startup a compressor have been simulated. These scenarios were analyzed to find optimal power consumption and time requirements for startup of a model LNG compressors. This work gives some insight into how dynamic simulation can be used to evaluate different start up scenarios of a compressor.
