The key to the production of aviation kerosene storage tanks

Post author By decanter centrifuge manufacturer
Post date December 29, 2021

How to improve the reliability of aviation kerosene storage tanks? Aviation kerosene storage tanks are important fuel supply equipment for aviation oil companies. The importance of the manufacturing and production of aviation kerosene storage tanks directly determines the reliability of the transportation of aviation kerosene and the high-end quality of aviation kerosene.

The reliability of the use of aviation kerosene storage tanks requires strict control over the entire process of drawing design and manufacturing of aviation kerosene storage tanks. In view of the difficulties in the production and production of kerosene tanks, it is necessary to optimize the treatment plan and the specific operations of on-site production.

To improve the reliability of aviation kerosene storage tanks, attention should be paid to the following three difficult issues:

1) Difficulties in the production of the conical bottom of aviation kerosene storage tanks: There are certain difficulties in the production of the conical bottom of aviation kerosene storage tanks. The design and production of the slope of the tank bottom is a difficult point. To achieve a satisfactory degree of coordination, detailed analysis needs to be done in advance, the designed slope must be adapted to meet the specific use standards, and the bottom of the kerosene storage tank must have good integrity and the bottom plate can be coordinated with the tank body. Unite. The welding treatment of the conical bottom of the aviation kerosene storage tank is also very important. The number of welds should be reduced to a minimum, and the problem of welding deformation should be controlled.

2) Difficulties in installing the upper and lower end walls of aviation kerosene storage tanks: The difficulty in installing the upper and lower end walls of aviation kerosene storage tanks lies in the corresponding stress control, which requires strict control from the error aspect to avoid tank deformation caused by corresponding stress concentration. . The verticality, perimeter, and levelness of the upper and lower end wall panels of aviation kerosene storage tanks also need to be strictly controlled and corrected to ensure better forming integrity of the kerosene storage tank.

3) Difficulties in welding requirements for aviation kerosene storage tanks: In the manufacturing process of aviation kerosene storage tanks, the welding requirements for kerosene storage tanks are very high. The welding operation of kerosene storage tanks is actually closely related and mutually influencing with the shape requirements of aviation kerosene storage tanks. During the welding process, it is necessary to control weld defects caused by stress concentration. For the problem of welding seam defects, it is necessary to operate from the main aspect of welding scientific and reasonable design.

The above has explained the key points of the production and production of aviation kerosene tanks through three difficult aspects. To provide high-quality aviation kerosene receiving and dispatching operations, we must first handle the reasonable layout during the design stage of the aviation kerosene storage tank, and rationally arrange the steel plates and welds. At the location point, during the production process, the operation must be strictly abided by the regulations. After such a serious and strict production process, the reliability of the aviation kerosene storage tank can be improved.

Decanter centrifuge is a commonly used drilling mud processing equipment

Post author By decanter centrifuge manufacturer
Post date December 29, 2021

Decanter centrifuge is a commonly used drilling mud processing equipment. The decanter centrifuge has the advantages of good separation performance, strong adaptability, continuous automatic operation, small exercise intensity, small footprint, and low maintenance cost, so it has won the recognition of customers.

Decanter centrifuges are more suitable for the harsh on-site working conditions of oil field drilling. The centrifuge uses the principle of centrifugal sedimentation to separate the drilling suspension. The suspension enters the drum from the feed pipe through the liquid outlet hole in the screw pusher, and the solid particles are pushed to the inner wall of the drum under the action of centrifugal force and pushed by the screw. The blades on the feeder are pushed to the slag discharge port at the small end of the drum, and the liquid phase overflows through the overflow hole at the large end of the drum. Such continuous circulation, in order to achieve the purpose of continuous separation. Centrifuge is used in the drilling mud treatment process to work reliably and have a long life.

The screw propeller, the key component of the centrifuge, is made of thick steel plate. The thickness of the wear-resistant layer on the surface is twice as thick as before, and the surface is sprayed with tungsten carbide. Ensure the ultra-long life of the centrifuge. The main bearing adopts imported high-quality bearings, and the differential adopts high-precision hardened gear transmission. The use of a decanter centrifuge to process drilling mud is based on the characteristics of petroleum drilling fluids. Special equipment for solid-liquid separation is designed to complete various processes such as feeding, centrifugal sedimentation, and unloading at full speed. It is mainly used to recover barite , To remove fine solids, reduce the solid content of the drilling fluid, control the density and viscosity of the drilling fluid, ensure the performance of the drilling fluid, and play an important role in rapid drilling.

Five schemes for remediation of oilfield soil pollution

Post author By decanter centrifuge manufacturer
Post date December 22, 2021

The sources of oilfield soil pollution are mainly from the invasion of drilling mud during oil and gas exploration, extraction, transportation and storage. If the contaminated drilling mud cannot be disposed of in a timely, reasonable and effective manner, serious pollution of the soil around the oil field will occur. As the main source of pollution, drilling mud contains pollutants such as petroleum, heavy metals, organic chemicals, chloride ions and other pollutants that enter the soil without treatment, which will not only cause great harm to the soil, but also to the environment. The content of trace harmful elements in the soil exceeds the background value, and the content is too high due to excessive deposition, so it is called “soil heavy gold pollution”. Five schemes for remediation of oilfield soil pollution:

1) Oil sludge thermal desorption method oilfield soil pollution remediation plan:

The sludge thermal desorption method to remediate oilfield soil pollution is based on an integrated solution of solid-liquid separation. Through sorting equipment, the stones, weeds, tree roots and other sundries in the contaminated soil are separated; the proportions of oil and water are different. Physical properties: water, oil, and mud sand are fully stratified through water temperature and chemical stirring. The oil floats on the top layer according to the specific gravity. The water layer is in the middle, and the mud sand settles at the bottom layer. Finally, it passes through three-phase separation equipment or oil-water separation equipment. And mud-water separation equipment to achieve the purpose of three-phase separation of water, oil and mud.

2) Bio-method oilfield soil pollution remediation plan:

Bio-method oilfield soil pollution remediation program: Bioremediation is a method that uses biological growth and metabolism to degrade and transform organic matter. It has the characteristics of safety, reliability, and low repair costs. This soil pollution remediation plan includes: key processes, remediation preparations, supporting equipment and other core technologies.

3) Physical method of oilfield soil pollution remediation plan:

The physical method of oilfield soil pollution remediation program refers to pollution control technologies such as the soil method, incineration method, physical separation method, solution leaching method, solidification stabilization method, thermal desorption method and electrodynamic method based on physical methods.

4) United Technologies Oilfield Soil Pollution Remediation Plan:

The composition characteristics of oil and secondary metabolism determine the difficulty and complexity of oilfield soil pollution remediation. Therefore, a single technology cannot solve the pollution problem well, and it is necessary to consider the combined use of various treatment technologies.

5) Remediation plan for soil pollution of oilfield by leaching method:

The leaching method for remediation of oilfield soil pollution is an in-situ remediation method, which is very similar and close to the technical principles of “water flooding” and “polymer flooding”. The water from the injection well flows into the soil contaminated area of the oilfield, so that the oil contaminants in the oilfield soil are flushed into the area that can be pumped out by the groundwater well under the accumulation and driving of the water. The extracted petroleum-contaminated groundwater and flushing water are treated by surface facilities, and the rinsing water is recycled and reused. After the treated wastewater meets environmental protection requirements, it is discharged. When choosing an oilfield soil pollution remediation plan, different soil pollution remediation plans should also be selected for the oilfield soil contaminated by light oil and heavy oil.

Construction Mud Treatment-mud dehydration and drying equipment

Post author By decanter centrifuge manufacturer
Post date July 25, 2021

Improper treatment of construction mud will pollute the environment, cause a large amount of soil erosion, block up rivers, affect water quality, and destroy municipal facilities. Early Construction Mud Treatment methods included landfilling, natural drying, etc. These more primitive methods have lower costs, but they cannot meet the increasing Construction Mud Treatment needs.

Therefore, the mud dehydration and drying treatment introduced in recent years has the following contents:

(1) Vacuum suction filtration method: the effect is poor, because the mud settles in the lower layer. When the vacuum is applied, the mud layer becomes denser and the water is difficult to suck out.

(2) Filter press method: The effect is good, but it is difficult to use on the construction site.

(3) The centrifugal dehydration and drying method is better than the above two methods. The centrifugal closed automatic and continuous operation does not require flocculation equipment. It is suitable for on-site construction environment and can fundamentally replace the current original and backward processing methods and improve processing efficiency. Reduce processing costs, protect the urban environment, and achieve civilized construction on site.

Working Principle of Vacuum Degasser

Post author By decanter centrifuge manufacturer
Post date June 20, 2021

The Vacuum Degasser separates the gas (CH4, H2S, etc.) in the drilling fluid through compulsory measures, which can stabilize the specific gravity and viscosity of the drilling fluid, stabilize the performance of the drilling fluid, blowout and blowout accidents, and reduce cavitation. In the suction pipe mud tank, it can be used as a high-power agitator under the condition of no air immersion in the mud.

Working Principle of Vacuum Degasser：

1. The suction of the vacuum pump is used to make the mud enter the vacuum tank, and the gas is pumped out of the vacuum tank by using it. The vacuum pump plays two different roles here.

2. The water ring vacuum pump is always in an isothermal state during the working process, suitable for the suction of flammable and explosive gas, and has reliable safety performance.

3. The mud is shot to the four walls at a high speed through the window of the rotor, the bubbles in the mud are broken completely, and the degassing effect is good.

4. The main motor is biased and the center of gravity of the whole machine is lowered.

5. The belt drive is adopted to avoid the complexity of the deceleration mechanism.

6. The application of the steam-water separator does not cause water and air to be discharged at the same time, so that the exhaust pipe is always unblocked. In addition, it can also circulate water to the vacuum pump, saving water.

7. The suction pipe is inserted into the mud tank and can be used as a high-power agitator when the mud is not immersed in air.

Structure and Composition of Vacuum Degasser:

The composition of Vacuum Degasser: 1, suction pipe 2, rotor 3, separation wheel 4, top cover 5, method blue blocking plate 6, exhaust pipe 7, vacuum pump 8, water supply pipe 9, gas-water separator 10, exhaust Short section.

Drilling waste treatment status and technology

Post author By decanter centrifuge manufacturer
Post date May 30, 2021

In the process of oil exploration and production, a large amount of waste will be left on the well site. In view of these harmful substances, how to adopt corresponding drilling waste treatment technology to minimize the harm caused by waste drilling fluid to the environment is a very important task for oil and gas field enterprises.

For a long time, most of the domestic oilfield drilling waste treatment is to directly solidify the waste liquid in the waste storage pool after the completion of the drilling and completion work. Due to the high water content in the total waste to be processed, this method consumes a lot of chemicals, has a high cost, and has an unsatisfactory effect, and it cannot completely eliminate the hidden danger of pollution.

With the requirements of local governments for environmental protection, the current domestic onshore oilfields are gradually paying attention to the harmless treatment of waste drilling fluid. Therefore, the treatment technology route with solid-liquid separation technology as the core has begun to be used in drilling waste treatment. This technology has changed from simple and rough direct solidification in the past to a process technology route combining chemical method, solid-liquid separation method and solidification method.
