  • Method of using an aqueous chemical system to recover hydrocarbon and minimize wastes from sludge deposits in oil storage tanks
    Patent number: 5085710
    Abstract: Sludge deposited in a crude oil storage tank is treated with a warm-water based nonionic surfactant to minimize waste and recover hydrocarbon. The process entails draining oil from the storage tank, adding water with a nonionic surfactant, and adding diluent to recover hydrocarbon. The tank contents are heated to 145.degree. F. to 180.degree. F. When no sludge remains on the tank bottom, the diluent layer containing the recovered hydrocarbon can be drained directly into the crude unit, without upsets, and the aqueous layer into the API unit.
