HOME| MARKETS | Oily Sludge Treatment

The indirect thermal desorption process and equipment for we developed for oily sludge has filled the industry blank in China.

Research history: since the year 2005, our company has been to investigate and survey international and domestic oily sludge treatment technology, after several years introduction, R&D and innovation, in 2012, we have successfully developed oily sludge treatment device which suitable for many industry applications- OSTDS.

This technology has applied for 15 patents, 6 patents for invention, and has been awarded 9 patents, one of them is patent for invention, 4 professional academic paper have been published. 5 successful engineering projects applied in oilfield.

Application field

1、 Oily sludge produced by oil exploration: oily sludge, oil-base mud;

2、 Oily sludge produced by oil transportation: oily sludge, sludge in tank bottom;

3、 Oily sludge produced by wastewater treatment station: oil tank sludge, oil separator tank sludge, scum from DAF.

4、 Petrochemical sludge.

Process: In the practical application, we provide specific technical design proposal for different oily sludge property. Wet sludge reduction-pretreatment, the other sludge directly goes into the indirect thermal deposition device.
