In these processes, large numbers of chemical products are produced to satisfy human demands in daily life. Recently, economy globalization has resulted, in growing worldwide competitions in tradi.tional chemical .process industry. In order to keep competitive in the global marketplace, each company must optimize its production management and set up a reactive system for market fluctuation. Scheduling is the core of production management in chemical processes. The goal of this paper is to review the recent developments in this challenging area. Classifications of batch scheduling problems and optimization methods are introduced. A comparison of six typical models is shown in a general benchmark example from the literature.

The process was simulated by a constant holdup modeland solved by two point implicit method. Acetone and methanol mixturewas separated in such a setup using water as solvent. The simulationagrees well with experimental results. The experimental andsimulation results show that the solvent at the bottom and theproduct at the top of the column can be withdrawn simulataneously fora long period of time. It needs more time for the solvent to reachhigh purity than that required for the more volatile component toreach high purity, so that the time to withdraw solvent from thebottom is delayed.展开更多
