Cyclic distillation is an emerging process intensification technology, which can improve the separation efficiency compared to conventional distillation. Since most current models only account for the mass transfer, there is a lack PROCESS SYSTEMS ENGINEERING AIChE Journal DOI 10.1002/aic.16259 This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

Such a model is presented in this paper and using this model selected case studies, describing binary and multiple component systems with both ideal and non-ideal liquid phases, are investigated. The presented stage model allows for the modelling of both mass and energy transfer for a cyclic distillation process and allows for multiple feed locations as well as side draws. With the energy balances included the dynamic vapour flow rate can be described. This was shown to have a significant effect on the separation, especially for cases where the change in the vapour flow over the column height was high.
