Patent number: 8920631Abstract: The invention relates to a method for removing sulfur from crude oils using a catalytic hydrotreating process operating at moderate temperature and pressure and reduced hydrogen consumption. The process produces sweet crude oil having a sulfur content of between about 0.1 and 1.0 wt % in addition to reduced crude density. The method employs least two reactors in series, wherein the first reactor includes a hydroconversion catalyst and the second reactor includes a desulfurization catalyst.Type: GrantFiled: November 8, 2012Date of Patent: December 30, 2014Assignee: Saudi Arabian Oil CompanyInventors: Stephane Cyrille Kressmann, Raheel Shafi, Ali Hussain Alzaid, Esam Z.
