Abstract
An integrated process for the production of normal paraffins from a feed mixture of normal paraffins, iso-paraffins and aromatics is disclosed. The process integrates a normal paraffin sorption process and an aromatics sorption process. The normal paraffin product of the process of our invention meets the commercial requirements for production of detergents, including sufficiently-low concentrations of both iso-paraffins and aromatics. The process achieves these results without the need for two additional factionation columns that are necessary to prior unintegrated processes.
