    China Thermal Desorption Unit for Refinery Oily Sludge Treat

    Thermal Desorption Unit (TDU) is an energy recovery system which removes the chemical contaminants from soil ,oily sludge and other solids waste by heating the material at low temperature and oxygen free  condition.

    The alkane and other substances contained in the oily sludge are converted into three phases: gas, liquid and solid.Vapors are cooled in the condenser and discharged to a liquid recovery tank. Solids arel cooled down prior to recycling or backfilling. Avoid secondary pollution to the environment。

    FD Petrol thermal desorption system composed of feeding system,rotating heat exchanger,air emission purification unit,oil water separation unit,automatic control system.Suitable for oilfield sludge ,refinery sludge ,disposed oil based drill waste  and other various mixed domestic garbage sludge. After treatment ,the oil on solids <0.3% which is better than《Control standard of contaminent in agriculture sludge》(GB4284-2018) Grade B 0.3% rated value.Air emmission comply with 《Oil refinery industry contaminent discharge standard》(GB31570-2015).

    FD Petrol TDU system can be skid  ,mobile or stationary depending on capacity and composition of the material to be processed.
