Design a New Controller for Lube Oil Blending System

E N Al-Kahwaji, Mohammed ST Badran*, M Abdel-Geliel and A Amer

Blending applications are important, especially in petroleum sector, and it is not only limited to oil refineries, but also used in many other applications and other processes where different ingredients are mixed according to a defined recipe. Blending in petroleum sector is accomplished by blend base oil and certain additives to produce the finished product (Mineral oils). This paper deals with Lube Oil Blending, Two techniques are used in Blending, Automatic Batch Blending (ABB) in tanks or vessels, and In Line Blending (ILB) in pipe lines. Some oil companies suffer from the disruption of the second type of blending technique due to their long periods of operation. The problem is the loss of communication between the field controller in the line blending unit and the main control system in the control room, where the recipes cannot be transmitted from the main control to the field controller. This paper presents the design of a new blending unit and a controller called "the new blend controller for ILB", where a real-time, multi-tasking operating system is utilized to operate this unit. This new technology is designed to be run either standalone, or to be integrated as part of other systems. This new controller can be integrated with the existing system to solve the problem of communication between the control unit and the main control. In addition, this unit is used in the preparation of new recipes quickly and efficiently, rather than experimenting on the real system and then that recipe’s data can be transferred to the main control unit of the real system for mass production.
