Automatic Control of Emulsifier Consumption in Oil Treatment Unit

摘要

The paper examines the problem of oil-well product processing on an oil treatment unit, particularly a matter of water-oil emulsion breaking with the use of demulsification. The oil treatment unit is considered in general terms, the water-oil emulsion breaking process has been analyzed, and an automatic control system has been design as the result of the work. Modal predictive control has been selected as a control algorithm. The developed automatic control system allows users to maintain an optimal process control, to reduce costs, and to improve the quality of treated oil. In the research we face the problem of automatic control to supply demulsifier in complex oil preparation in real time depending on temperature and output amount with the use of PID and MPC controllers. Models of automatic control system of demulsifier feed with different types of regulators are constructed, results are compared and conclusions are drawn about the appropriateness of the use of a particular type of regulator.
