Abstract

Open and non-conventional closed batch column operation modes were compared by rigorous simulation. The configurations studied were the batch rectifier ("two vessel column"), middle-and multi-vessel column ("three and four vessel columns"). For the operation in closed system we studied six different modes differing in the operation of the vessels. We simulated the separation of test mixtures (n-hexane(A)-n-heptane(B), A-B-n-octane(C), A-B-C-n-decane(D)), and compared the recoveries under constant product purities. The effects of the operational parameters were also studied.
