In order to improve the ethane recovery rate in natural gas,the characteristics of the SRX ethane recovery process are studied,with a focus on examining the effects of the reflux ratio of the exported dry gas,the operating pressure of the demethanizer,the position and extraction amount of the gas phase side line of the demethanizer,and the subcooling temperature of the side line extraction gas phase on the ethane recovery rate and total compression power.The results show that increasing the return flow rate of the exported dry gas,reducing the operating pressure of the demethanizer,moving down the position of the gas phase extraction on the side line of the demethanizer,increasing the amount of gas phase extraction,and reducing the subcooling temperature of the gas phase extraction on the side line can effectively increase the ethane yield.
