Abstract

Abstract:

Taken feed locations of primary, atmosphere and vacuum distillation column as optimization decision variables, and maximum annual net profit as objective function, optimization model was established with kernel constrain conditions of distillation model, heat balance equation, and pump work equation and relative inequality constrain conditions. The optimization model was solved with the second development on Pro/II platform. The optimization feed location of each distillation column was achieved and good optimization result was yielded. The contributions of profit of each product, cost of crude oil, pump work, heating duty, cooling duty and vapor to annual general profit were analyzed. Among contrastive relationships of profits and costs, the contribution of profit of each product to net annual general profit is most, that of decrease of pump work is more, but those increases cost of heating and cooling duty.
