KNOWLEDGE BASE SPECIFICATION TO AUTOMATE THE FLUID CRITICAL POINT OF FLUIDS

In this paper an analytical procedure implemented to structure the knowledge required by an expert system applied for controlling a chemical process is described. The analytical approach is based on L ifecycle of Systems and on Task Model approaches. It was validated with an experimental procedure related to the determination of the critical point of pure fluids (CO2, N2O, SF6) and mixtures of low concentration (CO2-limonene). For the implementation of the control system an expert system shell (CHRONOS™) was used.
