Abstract
A process for treating a full boiling range naphtha is disclosed in which the mercaptans and diolefins are removed simultaneously in a debutanizer distillation column reactor. The mercaptans are reacted with the diolefins to form sulfides which are higher boiling than the C,and lighter portion of the naphtha which is taken as overheads. The higher boiling sulfides are removed as bottoms along with any C,and heavier materials. The bottoms are preferably taken to a splitter where a portion is taken as overheads and a heavier portion is recovered with the sulfides. This reduced volume of naphtha may be hydrogenated to convert the sulfides to H,S and diolefins, which may be hydrogenated to olefins and alkanes.
