Résumé / Abstract

An expert system was developed to select near-optimum acid gas treating processes in natural gas processing plants using heuristic knowledge from experts and literature. The near-optimum processes are defined as highly applicable processes for given conditions. The following subtasks are carried out in order by the system: determination of process combinations; selection of acid gas removal processes; selection of individual acid gas removal processes; selection of sulfur recovery units; selection of tail gas clean-up units. The selection of acid gas removal processes is performed with both fuzzy and'crisp'(conventional two-value) logic. The other subtasks are executed with the «crisp» logic. The developed expert system can select near-optimum processes. For the selection of acid gas removal processes, fuzzy logic is better than 'crisp' logic because it provides more rigorous and realistic solutions.
