Oily sludge is one of the dangerous substances in the process of petroleum development, refining, processing, transportation and production. It has a large output in the petroleum industry, and if it is not handled properly, it will pollute the surrounding environment. Harmless and resource treatment of oily sludge is an urgent problem to be solved, and it is also the requirement of sustainable development.
Classification of oily sludge
Oily sludge produced during crude oil exploitation. In the drilling operation, when the oil layer is detected, the operation of drilling and well testing may cause oil spill or blowout and produce oily sludge due to the action of ground pressure. In the process of crude oil production, crude oil detection, plugging, tubing fracture, workover operations, etc., may produce landing oil mud. This oily sludge has the characteristics of large oil content, fine particles, large viscosity and difficult water removal.
Oily sludge produced in the gathering and transportation process of oil fields. Oil field gathering and transportation is the process of collecting and treating the crude oil produced by each oil well in the oil field and transporting it to the oil depot or the export station respectively. The gathering station is a place where oil, water and gas are separated from the extracted crude oil, and the sewage station treats the separated water and refills the oil well. The gathering station and the sewage station are called the combined station. In order to maintain the formation pressure, most of the crude oil is injected with water first and then surfactant. After the formation pressure exists, the crude oil is transported to the surface through the oil well. With the deep exploitation of the oil field, the water content in the produced oil is increasing. Therefore, the oily sludge produced in the oil-water separation process of the joint station usually has a high oil content and water content, and a low solid content, which not only has asphaltene, aging crude oil, bacteria, but also has corrosion inhibitors, scale inhibitors, flocculants and other agents added in the sewage treatment process. There are two sources of oily sludge in the joint station: one is the bottom sludge of crude oil storage tank, settling tank and sewage tank; The second is the oily sludge formed by the overflow of sewage storage tank.
Oily sludge produced by the refinery sewage treatment process. Oil-bearing sludge in oil refinery, commonly known as “three mud”, has a large output, and usually has the characteristics of complex composition, difficult degradation, difficult settlement, difficult concentration and difficult treatment.
Characteristics and hazards of oily sludge
Oily sludge density is generally larger than water, oil content is high, generally 10%-50%, water content is 50%-90%, viscosity is large, dehydration is difficult, is a black viscous semi-fluid. The composition of oily sludge is complex, not only with a large number of aging crude oil, asphaltene, wax, colloids, bacteria, solid suspended matter, salts, corrosive products, acid gas, etc., but also in the production process added corrosion inhibitors, coagulants, fungicides, scale inhibitors and other water treatment agents, is one of the main pollution sources in the oil industry.
Oily sludge is rich in organic matter, salt, nitrogen, phosphorus, sulfur and other nutrients. If it is directly discharged into the surface water body or under the action of precipitation, the organic matter and ammonia nitrogen will consume a large amount of oxygen in the water body, resulting in eutrophication of the water body and seriously affecting the balance of the aquatic ecosystem. In addition, oily sludge also contains heavy metals such as copper, zinc, chromium, cadmium, mercury, lead and pathogenic bacteria, parasites (eggs), polychlorinated biphenyls, dioxins, radionuclides and other toxic and harmful substances that are difficult to degrade, which will not only pollute the environment, but also affect human health, leading to many fatal diseases, and even carcinogenic, teratogen, mutagenic effects. Therefore, in 1998, the State Environmental Protection Bureau classified oily sludge as waste mineral oil and mineral oil waste (HW08 item) hazardous solid waste, and required harmless disposal before discharge.
Xi ‘an KOSUN oily sludge treatment process
The processing process is: The material to be treated is fed by the belt conveyor into the spiral sand washing machine, the sand treated by the spiral sand washing machine enters the fine particle sand removal machine, the fine particle sand is crushed and cleaned, part of the oil is separated into the oil storage tank by the scraper, the sediment is transported to the vibrating screen by the centrifugal pump for dehydration, and the particles larger than 0.5mm are separated. >74 micron <0.5mm particles and sediment are processed by centrifugal pump into cyclone, <74 micron particles are separated and dehydrated by centrifuge, and <2 micron materials are processed by air flotation machine. The sand after air flotation treatment is discharged and dried, and the water after air flotation treatment is reused by spiral sand washing machine. The oil sewage of the spiral sand washing machine enters the oil sand separation tank for treatment. After treatment, the oil enters the oil storage tank for recovery through the scraper. The fine sediment after precipitation is transported to the vibrating screen by the centrifugal pump.
Drilling fluid centrifuge is an essential equipment in oil drilling engineering, its main function is to separate solid particles in drilling fluid to ensure the performance and quality of drilling fluid. Selecting suitable drilling fluid centrifuge is of great significance for improving drilling efficiency, reducing drilling cost and protecting environment. This paper will discuss how to choose drilling fluid centrifuge from the following aspects.
First, understand the basic types of drilling fluid centrifuges
Drilling fluid centrifuges are mainly divided into the following types:
Sedimentation centrifuge: The use of centrifugal force to make solid particles in the high-speed rotating drum sedimentation separation.
Separation centrifuge: Through high-speed rotation, the liquid and solid particles of different densities are separated.
Filter centrifuge: Separates solids and liquids by filtering media.
Understanding the different types of centrifuges helps to select the right equipment for the specific drilling conditions.
Second, consider the properties of drilling fluids
The properties of drilling fluid are critical to the choice of centrifuge. Here are some key drilling fluid parameters:
Density: High density drilling fluids require higher centrifugal forces to effectively separate solid particles.
Viscosity: High viscosity drilling fluids require stronger centrifuges to handle them to avoid clogging.
Solids content: Drilling fluids with high solids content require more efficient separation equipment.
Third, determine the processing capacity
Processing power is one of the factors to consider when choosing a centrifuge. Processing capacity mainly includes two aspects:
Capacity: The volume of drilling fluid that the centrifuge can handle per unit time.
Separation efficiency: The proportion of solid particles that the centrifuge can separate from the drilling fluid.
Normally, the higher the processing capacity, the size and power requirements of the centrifuge will also increase accordingly.
Evaluate equipment performance parameters
When choosing a centrifuge, you need to pay attention to the following key performance parameters:
Speed: High speed means stronger centrifugal force, which can separate solid particles more efficiently.
Power: High power ensures stable operation of the centrifuge under high load conditions.
Wear resistance: The drilling fluid contains a lot of abrasive particles, and the wear resistance of the centrifuge directly affects its service life.
Consider the operation and maintenance of the equipment
Ease of operation and maintenance is also an important factor to consider when choosing a centrifuge. The details include:
Degree of automation: Highly automated equipment can reduce manual intervention and improve work efficiency.
Easy maintenance: Equipment that is easy to disassemble and clean can reduce downtime and improve equipment utilization.
Spare parts supply: Choose a brand with good after-sales service and spare parts supply, which can ensure the long-term stable operation of the equipment.
Economic analysis
Economy is a factor that cannot be ignored when choosing centrifuges. The economic analysis mainly includes:
Acquisition cost: The initial investment cost of the equipment.
Operating costs: including power consumption, maintenance and other expenses.
Service life: Although the initial cost of durable equipment is high, it is more economical in the long run.
Seven, environmental performance
With the increasingly stringent environmental requirements, it is particularly important to choose centrifuges with good environmental performance. Environmental performance is mainly reflected in:
Noise control: Low noise equipment is more friendly to the environment and operator.
Emission control: Effective solid waste separation and treatment can reduce environmental pollution.
conclusion
Selecting a suitable drilling fluid centrifuge requires comprehensive consideration of many factors, including equipment type, drilling fluid properties, processing capacity, performance parameters, ease of operation and maintenance, economy and environmental performance. Through analysis and evaluation, centrifuges suitable for specific drilling conditions can be selected to improve drilling efficiency, reduce costs and protect the environment.
In the process of oil and gas drilling, water-based mud is generally used in shallow Wells, and oil-based mud is used in deep Wells. Conventional solid control equipment can effectively recover heavy stones and useful drilling fluid items. Suppose these solid phase parts containing heavy metals and compounds (about 12% to 18% oil content) are discharged without treatment. In that case, long-term precipitation will cause great harm to the natural environment such as vegetation, soil, groundwater, and human living environment.
With the continuous improvement of environmental protection requirements, higher requirements have been put forward for drilling site cuttings treatment. The emergence of a drilling waste treatment and purification system can not only solve the site’s environmental problems but also carry out secondary recycling and treatment of the waste generated by the on-site solid control system. While retaining useful mud to the maximum, the drilling cuttings after reprocessing are centrally solidified. Reduce the damage to the surrounding environment.
To effectively dispose of oil-based mud drilling waste, it is necessary to use professional oil-based mud non-landing equipment and systems. The equipment used to deal with oil-based mud is: a screw conveyor + drilling cuttings dryer + environmental protection centrifuge, through this equipment, can effectively dispose of the well site waste mud, and the treated drilling cuttings can also be reused.
Oily sludge (hereinafter referred to as “sludge”) is a substance composed of water, mud, oil and other impurities. Due to the diversity of sources of sludge, its composition is complicated and it is difficult to control. Its main sources include ground oil spill, ground oil sludge, tank bottom sediment and oil sludge produced in the process of refining. These sludge not only pollute the environment, but also affect the normal progress of production and life. Therefore, effective treatment of oily sludge is particularly important.
Oily sludge treatment method
At present, the main methods for the treatment of oily sludge include physical method, chemical method, biological method and hot washing method. Among them, the hot wash method stands out among many methods because of its efficient and clean characteristics.
Physical method: the sludge is separated and treated by physical means such as gravity sedimentation and centrifugal separation. This method is suitable for the separation of impurities and oils with large particles, but it cannot completely remove small particles and organic matter.
Chemical method: Use chemical reaction to change the physical properties of sludge, such as adding chemical agents to separate oil and water. However, chemical methods often have shortcomings such as residue of chemicals and secondary pollution to the environment.
Biological method: The use of microorganisms to degrade organic matter in sludge, although this method is environmentally friendly, but the treatment cycle is long, and the environmental conditions are high.
Hot wash method: It is one of the most effective oily sludge treatment methods at present. The hot washing method mainly separates the impurities and oils in the sludge by hot water and detergent under high temperature and pressure environment. The method can effectively remove small particles and organic matter, and the treated sludge is of high quality and can meet the standard of reuse.
Third, the steps of hot washing treatment of oily sludge
Pretreatment: Preliminary classification and screening of oily sludge to remove large impurities.
Hot washing process: the pre-treated oily sludge is placed in a high temperature and high pressure environment, and stirred by adding detergent. In this process, oils and impurities are broken down and separated under the action of detergents.
Solid-liquid separation: The mixture after hot washing is separated by solid-liquid separation equipment to obtain solid waste and clean liquid.
Waste treatment: Further processing and treatment of solid waste, so that it meets environmental protection emission standards or can be reused standards. The clean liquid can be reused or disposed of after further treatment.
Fourth, the advantages of hot washing method
High efficiency: Hot washing method can quickly treat a large number of oily sludge in a short time.
Cleanliness: Oily sludge treated by hot washing method has high cleanliness and good quality.
Environmental protection: there is no secondary pollution in the hot wash treatment process, and the treated waste can meet the environmental discharge standards or reuse standards.
V. Conclusion
With the rapid development of industry and the improvement of human awareness of environmental protection, the treatment of oily sludge becomes more and more important. Hot washing method is the best choice to treat oily sludge because of its high efficiency and clean characteristics. However, in the specific implementation process, it is also necessary to pay attention to environmental protection, resource reuse and other issues, to ensure that no new pollution sources are generated in the process of treatment, and to achieve true green production and life.
