A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. A naphtha feed stream may be separated into a normal paraffin stream and a non-normal paraffin stream. An isomerization feed stream may be taken from the non-normal paraffin stream and isomerized over an isomerization catalyst to convert non-normal paraffins to normal paraffins and produce an isomerization effluent stream. The isomerization effluent stream may be separated into a propane stream and a C4+ hydrocarbon stream optionally in a single column. The C4+ hydrocarbon stream may be recycled to the step of separating a naphtha feed stream.

The present invention relates to the fractionation technology that is used to create purified phenol and acetone products. More specifically, the present invention relates to a fractionation technology that is used to create crude acetone and crude phenol streams using a dividing wall column intended to remove cumene, alpha-methyl styrene and water from the product side of the wall.

Process for producing para-xylene are described. The processes utilize a dual raffinate approach. Two raffinate streams from the adsorption separation unit are fed to the raffinate distillation column independently to take advantage of the differing desorbent concentrations in the two raffinate streams. The process yields significant reboiler duty savings and a reduction in overall fired fuel needed.
