Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A process to reduce the sulfur and nitrogen content of a hydrocarbon oil feedstock containing organosulfur compounds and organonitrogen compounds, the process comprising: a. introducing the hydrocarbon oil feedstock and hydrogen gas to a catalytic reactor; b. conveying a catalytic reactor effluent stream to a high pressure separator to separate a hydrogen stream and a mixed high pressure separator effluent, the mixed high pressure separator effluent includ…
