Analysis of comprehensive utilization plan for refrigerant water
In order to improve the utilization rate of refrigerant water in Daxie Petrochemical,CNOOC,corresponding utilization plans were pro-posed for the existing equipment,and the transfor-mation effects of each plan were analyzed using pro-cess simulation software.The results showed that by using refrigerant water to replace the ammonia com-pressor in the recontact system of the reforming unit,as well as using refrigerant water for light hydrocar-bon separation of desulfurization dry gas in the hy-drogenation unit,deep cold separation of ethylben-zene unit dry gas deprropene system,and deep cold separation at the inlet of styrene unit tail gas com-pressor,the problems of heavy hydrocarbon carrying in the hydrogenation desulfurization dry gas and overload of styrene unit tail gas compressor could be effectively solved,and the efficiency of the enter-prise could be increased by 28.27 million yuan/a.
