Patent number: 8992767Abstract: Initial high sulfur levels of a hydrocarbon feedstock are reduced to desired low levels without the need for integration of substantial new equipment or hardware with existing hydroprocessing reactors. Ionic liquids are utilized as organic sulfur extraction agents and are added to and mixed with the hydrocarbon feedstock containing organosulfur compounds downstream of an existing cold separator vessel. The ionic liquid and hydrocarbon mixture is maintained in a contact vessel under conditions which promote the formation of ionic sulfur-containing derivatives that are soluble in the ionic liquid to be formed, thereby enabling extractive removal and separation of the organosulfur compounds from the feedstock.Type: GrantFiled: March 24, 2011Date of Patent: March 31, 2015Assignee: Saudi Arabian Oil CompanyInventors: Omer Refa Koseoglu, Adnan Al-Hajji
