Abstract

Abstract Of The Invention A multi-stage hydrotreating process for obtaining ultra low sulfur diesel boiling range hydrocarbon having less than 10 ppm sulfur with elimination of external hot high pressure separator and avoiding the formation of recombinant mercaptans by way of removing hydrogen sulfide formed during hydroprocessing reaction in excess to that required for keeping hydroprocessing catalyst in active sulfided form comprising the steps of (a) mixing of a diesel boiling range hydrocarbon feedstock with hydrogen in predetermined quantities and sending to the first predominantly liquid phase hydroprocessing reaction stage. (b) Effluent from the first hydroprocessing reaction stage is sent to first separator zone of open and empty space housed in the upper part of the second hydroprocessing reaction stage to flash off the dissolved reaction products hydrogen sulfide and ammonia. (c) Liquid part of the effluent of first hydroprocessing reaction stage which settles at the bottom part of first separator zone is passed to the second predominantly liquid phase hydroprocessing reaction stage. (d) Repeating the process till the liquid product sulfur level of less than 10 ppm is attained and the liquid product is sent to further processing.
