Abstract:In order to reduce the energy consumption and the operating cost in the natural gas purification processes. Compared with the process of removing water, the process of removing sulfur consumed more energy in the natural gas purification processes; for this reason, an optimization model and an optimization method were set up in the process of removing sulfur. In this paper, we simulated and calculated the process of removing sulfur by the chemical software Hysys. Using the optimization model and the optimization method, we simulated and calculated the process of removing sulfur and optimized the operating parameters of the Moxi Natural Gas Purification Plant of Chuan Zhong Oil and Gas Mine of Petro China Southwest Oil & Gas field Company 50×104Nm3/d natural gas purification devices. After optimizing it showed that,in reaching the natural gas cleaning requirements, the energy consumption of the purification device of the process of removing sulfur is 4842.78kW and the purification devices saved energy of the removing sulfur by 12.35%. The optimization model and the optimization method brought considerable economic performance in the process of removing sulfur. The optimization model and the optimization method are versatile and also are used for optimizing operating parameters of other process systems.
