The design of multiproduct batch plants with process performance models

A model is presented for the optimal design of multiproduct batch plants, which uses process performance information. The process description resembles the familiar polynomial model for sizes and cycle times. While the former approaches considered constant values for the size and cycle time factors, they are considered as functions of a set of process variables. The results obtained show significantly improved solutions with this model, when typical chemical engineering unit operations are involved. Operating costs are naturally included
