Abstract
An integrated process for treating a vacuum gas oil, kerosene, naphtha and Diesel-containing feed, includes the steps of providing a reaction feed containing residue, vacuum gas oil, kerosene, naphtha, Diesel, hydrogen sulfide, ammonia, and C1-C4 gas phase compounds; providing a stripping gas; providing a washing feed; and feeding the reaction feed, the stripping gas and the washing feed to a stripping and washing zone so as to obtain a gas phase containing the hydrogen sulfide, the ammonia, the C1-C4 gas phase compounds, the naphtha, the kerosene, the Diesel and the vacuum gas oil and a liquid phase, wherein the reaction feed is provided at a reaction feed pressure of between bout 700 psig and about 3500 psig, and wherein the stripping and washing zone is operated at a pressure within about 80 psig of the reaction feed pressure.
