原油蒸馏过程是一个复杂的连续工业过程，其操作优化将为企业带来可观的经济效益，解决该问题的难点主要在于过程数据协调，过程建模及优化算法。针对某炼油化工有限公司原油蒸馏过程，进行了基于物料平衡的过程数据协调计算，建立了以过程严格机理模型为约束的轻油收率优化模型，并提出应用遗传算法求解上述高维非线性工程优化问题，取得了满意的结果。
Crude oil distillation process is a complex continuous industrial process, and its operation optimization will bring considerable economic benefits to enterprises. The main difficulties in solving this problem lie in process data coordination, process modeling and optimization algorithms. Aiming at the crude oil distillation process of a refinery and petrochemical co., Ltd., The process data coordination calculation based on the material balance was carried out. The light oil yield optimization model was established, which was constrained by the strict mechanism model. The genetic algorithm was proposed to solve the above problems of high dimensional non - linear engineering optimization , Has achieved satisfactory results.
