Expert system for solvent selection of CO2 separation processes

Abstract We present the development of a prototype expert system in a chemical engineering domain. The system is called the Solvent Selection Advisory System (SSAS), and it is used for preliminary selection of optimal solvents for CO 2 absorbers, given different user specifications and plant conditions. The system can function as both an advisory and a tutorial system. The selection of solvents is based on heuristics and visual illustrations of the problem help users learn about the domain. We describe development of the system on an expert system shell, G2 1 . Some preliminary testing and evaluation of the system are also presented.
