Demetallization of heavy oils with phosphorous acid
Patent
·
OSTI ID:6412206
An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process includes adding phosphorous acid to the hydrocarbon feed stream under suitable demetallizing conditions. It is believed that phosphorous acid reacts with the metals contained in the hydrocarbon containing feed stream to form oil-insoluble compounds that can be removed from the hydrocarbon containing feed stream by an conventional method, such as filtration, centrifugation, or settling/decantation.
