METHOD OF AND SYSTEM FOR WASHING OF TANK AND EXTRACTION AND PROCESSING OF LIQUID REMNANTS Russian patent published in 1997 - IPC

FIELD: mechanical engineering; tank washing. SUBSTANCE: method comes to suction and pumping out of remnants from tank, delivering washing water into tank, separating oil-water mixture into oil and water and delivering inert gas. Suction and pumping out means for removal of liquid remnants are arranged on one vehicle, means for delivering washing water and separating oil-water mixture into oil and water are arranged on other vehicle and inert gas generator is mounted on third vehicle. Hot water is used for tank washing. System for implementing proposed method has means for suction and pumping out liquid remnants from tank arranged on one vehicle, delivering washing water and oil-water separating, on other vehicle, and inert gas generator, on third vehicle.
