Abstract
A process for concurrently fractionating and hydrotreating of a full range naphtha stream. The full boiling range naphtha stream is first subjected to simultaneous thioetherification and fractionation to remove the mercaptans the light fraction and then to simultaneous hydrodesulfurization and splitting of the remainder into an intermediate boiling range naphtha and a heavy boiling range naphtha. The three boiling range naphthas are treated separately according to the amount of sulfur in each cut and the end use of each fraction.
