    China Thermal Desorption Unit for Refinery Oily Sludge Treat

    FD Thermal Desorption Unit (TDU) Working Process

    1.Feeding:screw conveyor or belt conveyor feed the material into heating chamber

    2.Heating:The main part in this system is the processor module. The processor module is integrated with all the necessary equipments to heat up the waste material to the required temperature.
    3.Oil water separator:The vapourevaporated  in  the  process  is  discharged  into the first condensation stage, where the oil is liquefied by use of cooled condensate.  The  recovered  oil  will  be  discharged  directly from  this  stage. In the second condensation stage the water also is liquefied by use of cooled condensate. A number of heat exchangers are built into the system, to cool down   condensates   and   recovered   liquids   to   the   required   temperature.

    4.Exhaust gas recycling: In the process of heating pyrolysis sludge, in addition to oil and gas, some combustible but non-condensable gas will also be generated. This gas will be fully burned by the combustion machine at the bottom of the furnace, and fuel can also be saved.

    5.De-dust :The dust and smoke generated during heating will be purified to local standard then discharge.

    6.Solids discharge:After thermal desorption treatment,the oil on material content will be <0.3% which can meet the environment and industry standard,the solids will be discharged through fully-sealed discharged device to ton bags ,avoid dust during whole process.

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