Patent abstract
A process for the removal of organic sulfur compounds, primarily oxygenated organic compounds, such as sulfates and sulfonic esters from a hydrocarbon liquid is disclosed which comprises contacting the hydrocarbon liquid with a coalescer comprising a mesh material which has been wetted by sulfuric acid. The hydrocarbon liquid may be the product from a sulfuric acid catalyzed alkylation process and contain sufficient sulfuric acid to remove the sulfates and sulfonic esters. Sulfuric acid may be added to the coalescer vessel counter current to the hydrocarbon liquid to improve the efficiency of the contacting and removal.
