Description:
Control of the overall steam system in a refinery or a large petrochemical plant can be one of the most difficult automation challenges, yet one of the most important since steam usage can be 40% or more of the total energy consumption at the site. There will normally be multiple steam headers at different pressure levels, each with multiple users and suppliers. Demand at each level is changing and changes in one header can induce disturbances in the others. The many users and producers distributed widely around the site with local controls further complicating coordination. There are also multiple control objectives for the steam system with differing priorities. Procedural automation is a systematic approach to handling these types of state dependent control problems. This paper illustrates the use of this technology to design and implement controls for a typical complex steam control system. Expected benefits from implementation of the control structure are presented.
