Retarding deposition of paraffin from crude oil or natural gas with alkaline liquids

摘要

An improved method for inhibiting the deposition of paraffins on the surface of equipment in contact with crude oil or natural gas streams containing paraffins. The deposition of paraffins may be reduced by first contacting the equipment with a sulfur trioxide containing fluid and then adding an aqueous solution containing hydroxyl ions to the crude oil or natural gas streams containing paraffins which are in contact with the equipment.
