将多目标优化软件modeFRONTIER同化工流程模拟软件PRO/Ⅱ相结合,模拟催化吸收稳定系统,并采用遗传算法多目标优化产品质量和能耗。优化结果表明干气与冷、热负荷都存在较明显的Pareto关系,根据Pareto解集可得出优化点,优化后干气质量提高了12.8%,冷、热负荷分别降低了4.4%和4.92%。这为优化催化吸收稳定系统的设计和实际操作提供了依据。
The multi-objective optimization software modeFRONTIER is combined with the chemical process simulation software PRO / Ⅱ to simulate the catalysis absorption stability system. The genetic algorithm is used to optimize the product quality and energy consumption with multi-objective. The results of optimization show that the Pareto relation exists between dry gas and cold and heat loads. According to the Pareto solution set, the optimization point can be obtained. The optimized dry gas quality increases by 12.8% and the cold and heat load by 4.4% and 4.92% . This provides a basis for optimizing the design and practical operation of the catalytic absorption stability system.
