The strategy is to recycle off-cut to the next batch as a part of the initial feed. This transforms the operation problem from a single-batch problem into a batch-to-batch problem. The pseudo-steady-state concept is applied to BREAD processes to simplify the optimization problem. Optimization based on maximizing batch capacity (CAP) for the batch-to-batch problem is demonstrated using three real chemistry processes. The results show that the optimal operating recipe and CAP when off-cut is recycled are similar to those in the case when off-cut is collected but not recycled and that the CAP is on average almost twice (93.3% more) the maximum that can be achieved when off-cut is not used. Therefore, recycling off-cut may not only save the trouble of processing the off-cut but also make the process more economical. ? 2015 American Chemical Society. |
