Kbs as an Operational and Tactical Tool for Operation of Distillation Columns

Abstract

This paper discusses the application of Knowledge Base Systems to distillation column groups for both normal operation and start up. The project aim was for a real-time KBS with a graphical front end providing on-line advice to the operators. The software Promass supports the process operational staff by offering operational advice in advance of executive shut down actions. The specific requirements of the Human Computer Interface in the different applications are discussed. Quality assurance in the development phases is discussed and a novel methodology is introduced to provide built in quality assurance. It is shown that this is applicable to modulating control (normal operation) but is unsuitable for the sequential nature of the start up process. The commercial benefits of the KBS system in the two applications are compared.
