  • System and process for in tank treatment of crude oil sludges to recover hydrocarbons and aid in materials separation
    Patent number: 6069002
    Abstract: A method for removing a sludge from a crude oil tank while recovering hydrocarbons from the sludge. The method is carried in the crude oil tank.
