Abstract
Mercury will be transferred into the output dry gas in the mercury-containing natural gas dehydration and dehydrocarbon unit.In order to reduce the mass flow rate of mercury in the output dry gas and consider the system energy consumption,HYSYS software was used to simulate a high mercury-containing natural gas dehydration and dehydrocarbon unit.The influences of the temperature of feed gas to the low temperature separator,the mass fraction of ethylene glycol and the mass flow rate of ethylene glycol on the mass flow rate of mercury in output dry gas and system energy consumption were investigated.On this basis,according to the response surface method,a multi-objective optimization model for key parameters,mass flow rate of mercury in the output dry gas and system energy consumption was established and NSGA-Ⅱ algorithm was used for multi-objective optimization.The results show that the error between the Pareto solution calculated by NSGA-Ⅱ algorithm and the HYSYS simulation value is less than 1％and the accuracy of NSGA-Ⅱ algorithm is reliable.The mass flow rate of mercury in output dry gas and system energy consumption both decrease by optimization of NSGA-Ⅱ algorithm.The Pareto solution set obtained by NSGA-Ⅱ algorithm can provide guidance for parameter optimization of natural gas dehydration and dehydrogenation process.关键词
