建立了催化裂化分馏塔多目标优化函数,并通过遗传算法对其求解,结果表明在某一组操作参数下生产,可以保证分馏塔重石脑油流量和轻柴油流量同时最优,此时多目标综合评价优化函数的适应度值为193.41,对应解下重石脑油流量Q_1和轻柴油流量Q_2分别为294.771(t/h)和92.053(t/h),均高于未进行优化的历史操作最高流量值Q_1=225.177(t/h)和Q_2= 53.700(t/h),实现了分馏塔的多目标优化。
The multi-objective optimization function of FCCU was established and solved by genetic algorithm. The results show that under a certain set of operating parameters, it can ensure that both the heavy naphtha flow and the light diesel oil flow in the FTU are optimal at the same time. The fitness value of the comprehensive evaluation optimization function was 193.41, corresponding to 294.771 (t / h) and 92.053 (t / h) respectively for heavy naphtha Q 1 and light diesel oil Q 2, which were all higher than those of the unopened historical operation The flow rates Q_1 = 225.177 (t / h) and Q_2 = 53.700 (t / h) achieved multi-objective optimization of the fractionator.
