Development of adaptive control system for technological facility of primary oil refining

Abstract

As it is known, primary oil processing facilities are designed for the production of light-colored oil products and various oil fractions that meet modern requirements with their quality. The main equipment of these technological facilities are rectification columns operating under atmospheric and vacuum conditions, which perform the decomposition of crude oil and fuel oil into various product fractions. Generally, the quality indicators of product fractions produced in these columns are provided by stabilizing the temperature modes at certain points (plates) of these or rectification columns by regulating the irrigation consumption supplied to those plates. It should be noted that currently, in accordance with the requirements of the time, the design and development of new control systems that can adequately respond to more dynamic and variable external and internal stimulating influences for complex oil refining technological facilities is one of the main problems facing the automatic control theory. The paper is dedicated to the issue of developing a new automated control system that can provide the required accuracy in terms of quality management. As an adaptive control system, the purpose of such systems is to compensate in time for disturbance influences in the technological devices and to ensure the production of oil products with stable quality indicators, regardless of these influences. The purpose of study is to develop a control system that can meet the given requirements and ensure the produced products with relatively stable quality indicators, regardless of the controlled and uncontrolled exciting effects affecting the oil refinery technological complex. The principle of operation of this system is based not only on the compensation of disturbance influences but also on the calculation of new operation strategies depending on these effects. The development of new automated control system that is able to provide the necessary accuracy of quality control in the lack of information is relevant
