Lefilter pyrolysis plant makes oily sludge treatment in oil field harmless

Oily sludge is an inevitable product during oilfield exploitation, which is characterized by high water content, toxicity, harmfulness and large volume. Moreover, the thermal wave of oilfield sludge is obvious, which contains a large number of suspended solids, bacteria and corrosives, and the oil content is between 2% and 50%. 

Different oily sludge has a large difference in nature, which can be divided into landing oil sludge, refining oil sludge and tank cleaning oil sludge according to the type. In the process of oilfield production, a large amount of oil sludge will be produced during downhole operation and production test; A large amount of oily sludge will also be produced due to pipe perforation and production accident blowdown. For a variety of reasons, the above sludge recovery and comprehensive treatment are very difficult, and improper treatment will cause serious environmental pollution.

Lefilter oil sludge pyrolysis plant heats oily sludge by using a fully closed circulating system to recycle the hydrocarbons in it. After treatment, the oily sludge can reach the safety discharge standard. The harmless and reduced treatment of oily sludge is complete, and the pyrolysis gas, carbon residue, pyrolysis oil and heat can be recovered. At present, there are hundreds of successful cases at home and abroad.

Proper treatment of oily sludge has significant economic and social benefits. As far as its economic benefits are concerned, the application of advanced oily sludge treatment by pyrolysis process in oil field can realize resource utilization, greatly saving production and waste treatment costs. From the perspective of social benefits, it can effectively change the status quo of long-term accumulation of sewage sludge in oil fields. It has significant ecological and environmental benefits. Waste can be recycled after treatment, and can drive the development of surrounding markets. In general, the comprehensive treatment and resource utilization of oily sludge in the oilfield can produce good environmental benefits, social and economic benefits, which are practical and beneficial to the country and the people.

The complete set of pyrolysis plant production line developed by Lefilter Shangqiu Branch can deal with various organic solid wastes, including oilfield sludge, waste tires, waste mineral oil, coal tar oil residue, medical waste, waste plastics, etc. It realizes the reduction, recycling and harmless treatment of organic solid wastes on the premise of safety, economy and environmental protection. From the perspective of comprehensive treatment effect, Lefilter cracking equipment has effectively solved the problem of safe production and environmental protection, and created significant economic benefits for the enterprise.
