Extending the parameter optimization method for the complicated non-linear utility system, a new synthesis method was developed for the simultaneous optimization of process structure and the steam parameters. The mixed integer non-linear program (MINLP) model was also proposed for a practical utility system. Based on the characteristic of the model, the mixed continuous evolutionary algorithm was used to solve this problem. The result shows that, though the model has strong non-linear, it reduces the scale of this kind of problem and the global optimization solution is obtained more easily. This model also strongly reflects the non-linear characteristic of the utility system.
