Abstract:

Separation-recycle system is an important part in chemical process, and its optimization is
a multiobjective problem. In this paper the process optimization procedure is proposed. The
fuzzy optimization algorithm with the concept of relative importance degree (RID) is
utilized to transfer multi-objective optimization (MO-O) model into a single-objective
optimization (SO-O) framework. The treatment of process condensate in synthesisa mmonia
plant is taken as example to illustrate the optimization procedure, and the satisfactory
result demonstrates feasibility and effectiveness of the suggested method.

Key words: multi-objective, fuzzy optimization, relative importance degree
