Investigation of factors affecting on viscosity reduction of sludge from Iranian crude oil storage tanks

Abstract Crude oil is a kind of water/oil emulsion, which the oil phase consists of organic molecules with different molecular weights such as alkanes, paraffin, asphaltene, and resins. Due to the change in physicochemical conditions during the production, transportation, storage, and refining, heav...
