Development of a Control System for a Fractionation Column in the Isodeparaffinization Process of Diesel Fuel

Abstract

Increasing the competitiveness of products manufactured by domestic enterprises has become an important task nowadays. This problem can be solved by improving the quality and reducing the amount of defects. Implementation of the proposed project will help to address safety issues in production processes, improve product quality, and working conditions. Development of automated control systems for technological processes based on modern microprocessor automation tools will significantly increase the speed and reliability of processes, as well as ensure safety and accuracy in task execution. The isodeparaffinization unit for diesel fuel is designed to produce arctic diesel fuel and diesel fuel MK1 that meet the requirements of the environmental quality standard "Euro-5" with minimal output of product oil. Analysis of the technological process as a control object allows selecting the structure of the control system, i.e., determining the regulating influences to maintain a particular technological parameter at a specified level, as well as the need to compensate for disturbing influences. The presented work has developed a set of measures and proposed technical solutions for creating a control system for the fractionation column in the diesel fuel isodewaxing process, which has brought the safety level into compliance with regulatory requirements and improved the quality of automatic control of the existing technological object.
