Abstract:

This study provides insights into the optimal operation of one of the most important refinery units, namely, the crude distillation unit (CDU）. A steady state model was developed to simulate an industrial CDU by using a process simulator, HYSYS. The elitist non-dominated sorting genetic algorithm (NSGA-Ⅱ) was used to solve a meaningful multi-objective optimization problem. It was observed that the economic benefit of the CDU could be increased while keeping the product quality within acceptable limits. This procedure used was quite general and could be applied to other CDUs.
