Crude oil is notorious for developing sludge on the floor of the storage tank. The tank has to be taken offline and cleaned, which is hazardous, expensive, time-consuming, and requires sludge disposal.
The Twister helps minimize the downtime needed for offline cleaning and/or tank entry prior to tank inspection and service intervals. The Twister works by directing a jet or plume of crude oil across the bottom of the tank, which dissolves and resuspends accumulated sludge. The Twister is fitted on a manway and replaces the existing manway cover, and requires no electrical or other power source other than a feed pump. This system allows the use of oil from the tank itself or a fluid from an outside supply source, such as cutter stock, to clean the tank.
It’s the permanent, easy to use, cost-effective solutio for storage tank cleaning!
