摘　　要：针对液化气进料中乙烷浓度的变化对丙烯收率的影响,运用正交实验设计安排实验,采用PRO/II流程模拟计算软件对气体分馏系统进行模拟计算,考查了丙烯收率的变化、影响因素的主次关系及显著性,得出结论为,使丙烯收率达到93%以上就必须限制液化气中的乙烷浓度在1%以下。The orthogonal experiments are used to study the effect of ethane concentration in gas fractionation unit to the propylene yield,and the process of gas fractionation unit has been simulated by PRO/II software.The changes of the propylene yield,the primary and secondary relationship between the influencing factors as well as the significance analysis are mainly studied,and it is concluded that for a higher yield of propylene than 93%,the concentration of ethane in raw liquid gas must be limited to a value lo...
