Due to the adsorption of the same charge on the surface of oily sludge particles, which repel each other, and coupled with sufficient emulsification, it is extremely difficult to destabilize, making the separation of oil, water, and sludge quite challenging. Further conditioning agents need to be added to separate crude oil from solid particles, polymerize oil droplets, and allow the added chemical agents to settle with solid impurities, achieving further separation of oil, water, and slag. For different types of oily sludge, it is necessary to determine the optimized flocculant, demulsifier type, and centrifuge operating parameters. This type of treatment method has a wide range of applications in oil field landing crude oil, oil sludge at the bottom of oil fields and tanks, as well as the dewatering of gelatinous sludge (water content ≤ 15%) generated during the treatment of oily wastewater in oil fields. This technology is easy to operate, with a high recovery rate of dirty oil and a de oiling rate of over 80%.

Indirect thermal cracking is the process of utilizing the thermal instability of organic matter in waste, heating it under anaerobic conditions to cause thermal desorption and thermal cracking of the organic matter. The organic matter is cracked according to its carbon to hydrogen ratio, forming a gas phase (pyrolysis gas) and a solid phase (solid residue) with high utilization value.

The MVR mechanical steam recompression device uses the secondary steam generated in the evaporation system to do work through a compressor, increasing steam pressure and enthalpy, circulating for heating and evaporation, fully utilizing the waste heat of the secondary steam engine condensate in the system, and achieving outstanding energy-saving effects. In addition to using fresh steam and waste heat raw material steam for driving, there is no need to use additional steam. The purpose of evaporation concentration is achieved through the self circulation of the evaporator, which can save 70-90% of energy consumption. The system consists of a preheater, evaporative heat exchanger, separator, and steam compressor.

The multi effect evaporation device utilizes new steam to heat the first effect, and the generated secondary steam enters the second effect for further heating and utilization, reusing this principle to further utilize thermal energy. The material liquid is heated and evaporated in multiple stages on the tube side for concentration, thereby reducing operating costs.
