Decision support system for solvent selection of CO/sub 2/ removal systems

This paper presents the development of a prototype expert system in a chemical engineering domain. The system is called the Solvent Selection Advisory System and it is used for preliminary selection of optimal solvents for CO/sub 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. In this paper, we describe development of the system on an expert system shell, G2. Some preliminary testing and evaluation of the system are also presented.<
