Abstract
A continuous process for upgrading sour crude oil by treating the sour crude oil in a two step process that includes a hydro-demetallization section and a hydro-desulfurization section, both of which are constructed in a permutable fashion so as to optimize the operating conditions and catalyst lifespan to produce a high value crude oil having low sulfur and low organometallic impurities.
