Limited to one Site Survey per business. Tank sludge is one of the more common problems oil tank owners have to deal with. If it is not caught and treated soon, then it can cause serious problems for you and your fuel supply.
Whether you require sludge removal from your location or you need to offload sludge at one of our facilities, Terrapure can help. We process hazardous and non-regulated sludge, including semisolids and liquids with suspended and bottom solids. Our treatment processes are engineered to maximize the recovery of oil, remove and treat water, and minimize residuals.
The present invention pertains, in general, to a method for removing sludge accumulated in a crude oil tank on storage of crude oil in an oil refinery, and recovering oil therefrom. More specifically, the present invention pertains to a method for removing sludge in a crude oil storage tank by use of thermal oil, such as atmospheric residue, vacuum residue and vacuum gas oil yielded from an oil refinery, and recovering oil having various applications by separating inorganics from the removed sludge. The problem begins when contaminants settle down on the bottom of oil storage tanks.

When crude oil is stored in large tanks, invariably high-molecular-weight organic sediments are deposited. If left to accumulate, these deposits build up to form a sludge, which causes a reduction in the storage capacity. Routine industrial maintenance of storage tanks in vessels, terminals, and refineries unavoidably means the equipment's temporary inoperability.
Sucking from the very bottom of the tank, independent of the engine running the Diesel Dipper will scour all water and sludge from the bottom of the tank below the fuel suction. When the boat is underway with the water and sludge sloshing about it will suck up everything leaving the tank bottom clean and dry. What is it?

Please take this quick survey to tell us about what happens after you publish a paper. Environmental Science and Pollution Research. Accumulation of oily sludge is becoming a serious environmental threat, and there has not been much work reported for the removal of hydrocarbon from refinery tank bottom sludge.
In an aqueous environment, this is an excellent angle for most solids to overcome friction-forces-per-relative-weight in a liquid carrier, and effectively move solids down to the bottom, without binding on the hopper walls. At a given tank width, the steeper the walls in the solids chamber the more solids-holding capacity is available. This is very important in on-going maintenance of the unit.
