Thermal Desorption Unit for oil tank bottom cleaning

Thermal desorption is an environmental remediation technology that utilizes heat to increase the volatility of oil such that they can be removed from the oil sludge or oil tank bottom. The thermal desorption unit is used for oil recovery and reduce hazardous waste for the environment. The recovered oil can be used for the operation of the TDU or be sold for money, the solids waste can be as waste injection, land fill or drain off in the sea, because after treated by TDU, the oil content in the solids waste is under 0.3%, which can be disposal directly. It is accepted by most of countries environmental protection laws. Not only for oil waste treatment, TDU can be also used for various materials, like soil, sludge, sand, filter cake, tank bottom, organic based hazardous waste and contaiminated soil. Just considering the total cost, some clients will not use TDU for low profit projects, we will recommend other equipments, like desander, desilter, shale shaker, decanter centrifuge, vertical cuttings dryer, etc.

The recovered oil is a mixture of oil and water, we will apply oil water separator to get pure oil. The oil water separator is a device designed to separate gross amounts of oil and suspended solids from the wastewater effluents of oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial oily water sources.

The power source of the TDU is coming from burning of oil, the oil consumption is max 80kg per hour for 2 burners. The recommend material is oil content less than 15%, water content less than 15%, the total fluids content less than 30%, and the max fluids content no more than 40%. If the fluids content is bigger than 50%, we can use pre-treatment equipments before TDU. For more information, pls contact GN solids control.
