摘　　要：应用通用流程模拟软件Aspen Plus对催化裂化的分离系统进行了模拟,在此基础上,考虑到该装置产品方案的多样性,以汽油终馏点、柴油95%馏出温度、干气C3体积分数和液化气C2体积分数为约束,建立了产品收率最大化、分离系统能耗最小化的多产品方案的多目标优化模型。应用多目标列队竞争算法(MOLCA)对模型进行了求解,所得最优解集Pareto前沿揭示了各产品方案能耗与收率的影响规律。结果表明,各产品方案的操作参数的最优妥协解均优于实际工况值,为催化裂化分离系统的设计与操作优化提供了重要参考。Based on the simulation of a FCC separation system using Aspen Plus sofLware, where the final boiling point of gasoline, 95% distilled temperature of diesel, C2 and C3 volume fraction in dry gas and LPG, respectively were used as the constrain conditions, a multi-objective model of maximizing the yield of product, minimizing the energy consumption of separation system is established in consider- ation of multi-product plan. Multi-objective line-up competition algorithm （MOLCA） was employed to solve the model, and the Pareto front obtained from the model reveals the influence rule of the energy consumption on the yield of product. The results indicate that the optimal compromise solt tions of oper-ation parameters are superior to that of real practice.
