Sažetak
Although potential for reduction of energy requirement and related carbon dioxide emis-sions is highly attractive – around 50% compared to conventional three column sequences –process industries are still reluctant to consider implementation of fully thermally coupledfour products dividing wall columns, mainly due to concerns related to controllability of twoor three vapour splits as encountered in complex DWC arrangements. This paper presentsresults of a simulation study that could bring some relief in this respect, indicating that atemperature-based control structure, in conjunction with tight control of temperature pro-files in prefractionation section, as well as in the product draw regions of the column, iscapable of restoring the operation to health from typical disturbances in feed quality andquantity. Combining temperature-based control with two composition controllers enablesthe column to be operated within finer margins, resulting in minimal over-purification andoverall energy requirement.
