Oil Sludge Treatment

Several Oily Sludge Management technologies

At present, the total amount of oily sludge produced in our country has exceeded 500 million tons every year, and the output also shows an increasing trend year by year. Oily sludge mainly from the following three aspects.( Oily Sludge Management)

(1) crude oil extraction process. Crude oil production process will produce a amount of oily sludge. The sludge produced mainly from the oil recovery wastewater treatment, the sedimentation caused by the added water purifying agent and the crude oil produced by drilling.

(2) Oil gathering process. Oil gathering process will produce a amount of oily sludge. Transfer stations and joint station tank sludge, sedimentation tank sediment, grease trap sediments are all oily sludge. Oil sands produced from natural gas purification plants and sludge are also oily sludge.

(3) Sewage treatment plant. Oil refinery wastewater treatment plant will also produce oily sludge, mainly from the biochemical pool of excess sludge, grease trap sediment, flotation tank scum, crude oil tank sediment.

Several Oily Sludge Management technologies

Oily sludge must be treated as it is detrimental to the environment. At present, there are several commonly used methods for the treatment of oily sludge in our country: incineration, thermal desorption, landfill, etc. In addition, there are biological treatment, coking and chemical heat washing.

In response to the requirement of resource-based, harmless and reduction of oily sludge treatment in our country, there are many new oily sludge treatment technologies emerging such as ultrasonic treatment of oily sludge technology, cement sludge co-treatment of oily sludge technology and Solvent extraction processing technology.

The source, composition, characteristics and nature of oily sludge in oilfields all over China are different, so the technology applied to oily sludge management is not the same. Therefore, the oil field in the selection of oily sludge treatment technology should be based on the advantages and disadvantages of various technologies and the scope of application. Combined with their own circumstances choose a reasonable technology.(Editor:Kosun Lily.Wang)

Prospects for Oil Sludge Management

With the promulgation of the new Environmental Law, the environmental requirements are getting higher and higher for oil fields, and free discharge of oil sludge will not be allowed any more. Oil Sludge Management is becoming a focal issue.

oil sludge management

Oil sludge is oil mixed with soil. They will be mixed together and become very difficult to deal with. Oil sludge is mainly from two aspects: Firstly, crude oil from the stratum to the ground and accumulated in all kinds of containers, large tanks and recycling pools and other ground facilities; secondly, oil sludge produced by oil well operations.

Oily sludge is mainly derived from oil field mining and sewage treatment plants. In general, the sludge oil content is from 10% to 50%, and moisture content is from 40% to 90%. The ultimate purpose of oil sludge management is to reduce the harmful resources. The common oil sludge treatment methods are solvent extraction, incineration, biological, coking, oily sludge profile control, and comprehensive utilization of oil sludge. The results show that the current methods for oil sludge management have their own characteristics and scopes of application. As the oil sludge composition is so complex, there is no treatment method that can treat all types of oily sludge.

According to statistics, the pollutant treatment market size is about CNY100~150 billion each year, and according to a rough calculation, the investment in oil sludge management plant needs more than CNY150 billion.

Since 2007, Daqing Oilfield have built nine oil sludge management stations, and the annual treatment capacity can reach 3.2 million tons, all the oil sludge had been treated harmlessly. Changqing Oilfield built a Longdong oil field sludge treatment station in 2013 and used the physically and chemically combined methods, the oil content of the treated oil sludge is less than 2%, and moisture content is less than 60%, while the crude oil can be recovered. Xinjiang Fengcheng Oilfield Work Zone uses microbial agents to deal with heavy oil sludge and sludge oil content is reduced from 15% down to below 2% after treatment, which is very good. The current test has been reviewed by the company.

KOSUN can provide a corresponding set of oil sludge management plant, and our products have been exported to foreign countries, such as the United States, Europe, Russia, the Middle East and other regions, and our oil sludge treatment systems are well received by the foreign customers.

Oil Sludge Treatment Plant

Oil Sludge Treatment Plant (equipment) :

–Shale Shaker for coarse solids separation

–Decanter Centrifuge for fine solids separation or water and oil separation.

-Oil Water separators for two phase liquid separation.

-Thermal desorption unit for minimize the oil on the solids down to 0.3%.

The oil sludge is the waste of solid with oil from oil drilling, transportation, refinery and oil waste water treatment processing. It contains big quantity benzene series, phenols, anthracene, pyrene and other harmful rotten material. It will be a resource waste and pollution for environment.

Oil sludge origin:

Crude oil drilling work
Rig site waste during gathering and transportation
Waste water treatment plant in refinery plant

Different areas and different clients has different oily sludge and final requirements for the oily sludge separation & treatment, following questions are needed to be clear for us to provide the best proposal for your oily sludge treatment solutions.

-What is the origin and geographic location of the waste sludge (drilling, refinery, other)?

-What is the makeup of the oil sludge (percentage of oil, water and solids)?

-What volume of oil sludge is to be treated?

-How long you need to complete the treatment of the oil sludge?

-What is the challenge or problem of the current situation?

-What is the target to achieve for the final oil, water and solids?

-What process / equipment is being used on location at present for the oil sludge treatment? How is the performance now?

-What’s your budget for the oil sludge treatment plant?

Knowning above queations,we can supply you suitable Oil Sludge Treatment Plant ! (Editor:Kosun Lily.Wang)
