Computer Control System of Crude Distillation Unit

Abstract

A computer control system of a crude distillation unit with a design capacity of 150,000 BPSD has been developed. The crude distillation unit consists of a topping unit and a gas recovery unit. The main purpose of the system is to optimize the former unit and to control products quality of the latter unit. In either case, most of the system has been put to practical use, and its application has proved to be satisfactory. The system concept and structure are described, and the usefulness of this system has been substantiated by the results of applications.
