Implementing Advanced Process Control for Refineries and Chemical Plants

In today’s globally competitive marketplace, chemical plants and refineries are looking at new ways to increase plant efficiency, production rates, safety and reliability. In the process control arena, base-level PID tuning optimization, APC (Advanced Process Control) and MPC (Model Predictive Control) remain attractive and under- utilized options. This paper describes various new and novel ideas harnessing the power from primary PID control improvements and APC/MPC implementation. The techniques and methodologies described can increase a plant’s profit margin from 2 to 10%. Spectacular increases in plant profits as high as 15 to 20% (equivalent to 2 million Euros/year) have been achieved and demonstrated in some cases. A few real examples from actual industrial plants have been provided in this paper.
