Centrifugal separation is the most popular measure to disposal oil-based mud

The traditional Oil-based Mud Treatment Technology is recycling and incineration.,simple processing and low cost. But this measures is higher demands on stratigraphy and the incineration can cause serious pollution to the environment, Not conducive to the construction of environmental conservation-minded society. At present, to meet emissions requirements, The mainly measures is through physical or chemical method to separate oil from the oil-based mud.

Incineration is that putting the cuttings waste of oil-based mud into a pyrolysis incineration device to achieve decomposed at high temperature and deep oxidation. In the process of incineration, consumed the oil in the cuttings and reduced the oil content greatly. But This method can produce a lot of smoke during burns, and it is also expensive to process.

Heat treatment method is that puting oil-based mud into the distillation column and rotaring evaporator to achieve full heating, then cooling collection until most of liquid oil and water evaporative. and discharge directly after the drill cuttings meet emission standards of oil content. But this method of processing costs is very higher. It is estimated that disposal drilling cuttings of one well need the total cost about $330,000.

Centrifugal separation is that using the principle of centrifugal to separate oil from oil-based mud. That is the specialized centrifugal separation equipment. It is vertical cuttings dryer. After centrifugal treatment, Water-based mud and composite mud: Water content 8-10%, oil-based mud: water content≤6%, OOC≤3%. and this equipment is the environmental and low cost treatment method. so it is the most popular measure to disposal oil-based mud.

technology of Decanter Centrifuge

Compared with other separation machines, centrifuges can not only obtain solid phase with low moisture content and liquid phase with high purity, but also have the advantages of small volume, good sealing, continuous operation and automatic remote excavation. Therefore, centrifuges are widely used in chemical industry, petrochemical industry, petroleum refining, light T, medicine, food, textile, metallurgy, coal, beneficiation, shipbuilding, environmental protection, military industry and other departments, Such as coal powder recovery in wet coal mining; Purification and reuse of drilling mud for oil exploitation; Enrichment of uranium isotopes; Sludge thickening and dewatering of sewage treatment; Refining of petrochemical products; Antibacterial cable, extraction of pesticides; Manufacturing of milk, yeast, beer, fruit juice, granulated sugar, orange oil, animal Cypress oil, rice bran oil, starch and other foods; Fabric fiber dehydration; Centrifuges are required for the purification of lubricating oil and fuel oil. It can be seen that centrifuge has become widely used separation equipment in all sectors of the national economy.

The application functions of centrifuge mainly include dehydration, clarification, concentration, classification, separation and so on. Different centrifugal models must be selected according to different material characteristics and separation requirements, which lead to the problem of centrifuge selection. In the actual production process, due to the selection of appropriate separation equipment in some projects, the process is simple, the energy consumption is reduced, the product quality is improved, and good economic benefits are obtained; However, some centrifuges are improperly selected, which makes the production process unable to proceed normally, resulting in great economic losses. Therefore, in engineering design and technical transformation, the problem of how to correctly select centrifuges has been recognized and valued by the majority of engineering and technical personnel.

Selection Decanter Centrifuge Model According Process

In the production process, there are different process requirements such as dehydration, clarification, concentration, classification and separation. The essence of dehydration and clarification is to separate the solid and liquid in the suspension from each other. Dehydration is to remove the liquid phase in the solid phase, and clarification is to remove the solid phase in the liquid phase.(Decanter Centrifuge)

Decanter Centrifuge-kosun
Decanter Centrifuge

A large amount of liquid phase, a small amount of solid phase, and the particle size of solid phase is very small (1o μ M) or amorphous mycelium, horizontal screw disc or tubular centrifuge can be selected. If the solid content is less than 1% and the particle size is less than 5rm, the tube type or zigzag type manual slag discharge can be used to separate vanadium. If solid content ≤ 3%, particle size < 5 μ m. Disc piston slag separator can be selected. The separation factor of tubular separator is high (f ≥ 1000, the separable particle size is about 0.5m. The finer particles have higher clarity, but the single processing capacity is small.

KOSUN is a professional manufacturer of Decanter Centrifuge for about 30 years, and we can supply capability of manufacturing decanter with bowl size from 220mm to 760mm.

    Linear Dewatering Shale Shaker is specially designed to separate larger and coarser solid particles. The construction mud enters the shale shaker through the feeding funnel, and separates large-diameter solids such as large stones. The screen on this shale shaker has a longer lifespan than traditional woven screens.
  2. Double-layer mud Shale Shaker
    After being screened by the Linear Dewatering Shale Shaker, the liquid phase enters the Double-layer mud Shale Shaker again. The Double-layer mud Shale Shaker is a two-stage separation. It first enters the bottom layer of the Double-layer mud Shale Shaker. The mesh number of the bottom layer is smaller, and the coarse particles are further screened. The mesh number of the upper screen is higher, and the liquid phase passing through the bottom screen enters the upper screen again, and the effect is better.
  3. Mud cleaner
    The liquid phase screened by the Double-layer mud Shale Shaker is pumped to the mud cleaner. The mud cleaner consists of two 10-inch desander cyclones and 12 4-inch desander cyclones plus a shale shaker. The liquid phase first passes through the desander cyclone, and then enters the desliming cyclone. After separation by the mud cleaner, the material conditions for entering the centrifuge are reached.
  4. Decanter centrifuge
    The separation capacity of the decanter centrifuge is more refined. In order to ensure a good use effect, the requirements for the materials entering the centrifuge are relatively strict, so the front coarse screen, fine screen and cleaner are processed. The centrifuge can separate solid particles above 2-5um. After the centrifuge treatment, it meets the customer’s requirements.
  5. Flocculation dosing system
    The flocculation dosing system is the icing on the cake. When the level required by the customer is higher, the flocculation dosing system can make the centrifuge more effective.

Centrifuges in the drilling solids control system and mud zero discharge system

The centrifuge is a common equipment in the drilling solids control system and the mud zero discharge system, so what is the difference between the centrifuges in the drilling solids control system and the mud zero discharge system?

Centrifuges in Drilling Solids Control Systems

The centrifuge in the drilling solids control system generally adopts medium and low speed centrifuges. Since the drilling solids control system adopts multi-stage solids control equipment, when the drilling fluid is filtered and separated from the mud shaker to the true remover to the sand and mud integrated machine after three-stage filtration and separation, the particle size of the mud particles has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuges have been able to meet the needs of slurry pulping.

Centrifuge in Mud Zero Discharge System

The centrifuge in Mud Zero Discharge System generally adopts a high-speed centrifuge or a frequency conversion centrifuge, which is a high-end centrifuge. The Mud Zero Discharge System is composed of a drill cuttings dryer and a high-speed variable frequency centrifuge. The Mud Zero Discharge System is located at the end of the solids control system and is used to process the drilling cuttings tailings processed by the solids control system, so the proportion of drilling cuttings tailings is very large, the solid particle size is large; because the centrifuge is to undertake the mud processed by the drilling cuttings dryer, the particle size in the mud screened by the drilling cuttings dryer is very large, and the requirements for the centrifuge are very high. Therefore, it is more appropriate to use a high-speed variable frequency centrifuge.

Waterway and river sludge dredging and dewatering treatment equipment

1) Excavator dredging equipment: first use the pump to drain the water in the river to the other side, and after it is drained, the excavator enters the river or waterway for dredging construction. Excavator dredging equipment is a relatively common dredging construction machinery and equipment. The advantages of using excavators for river channel dredging are that the operation is convenient and simple, the construction cost is low, and it is suitable for operations with dry and hard mud and shallow river depth construction.

2) Desilting equipment of vertical mud pump mud conveying system: the main components of vertical mud pump mud conveying system are: mud pump, floating body, mud conveying hard pipe, rubber hose, etc. Its working principle process: the pressure generated by the water flow through the centrifugal pump, through the water pipe and the water gun, spews a dense high-pressure water column for cutting and crushing, forming the flow state of the mixed liquid of mud and mud blocks. Pumps and mud pipes are sucked to the sludge dump. The mud pump dredging is not only easy to operate, but also conducive to improving water quality and protecting the ecological environment. Its main operating range is suitable for operation in mountainous and hilly areas, and also suitable for dredging of river channels with small water surface.

3) Cutter suction vessel dredging equipment: the main components of cutter suction vessel are mud pump and suction device structure. The pump sucks the sludge from the suction pipe, and the sludge discharge pipe discharges the sludge to the river bank or directly into the mud barge for transportation to a certain place for temporary storage and then for sludge dewatering treatment. The cutter suction boat is mainly aimed at the bottom of the river where the sludge is soft in the river channel.

4) Screw stacker sludge dewatering equipment: The working principle of this equipment is that after the sludge is first concentrated by gravity, the screw stacker is transported to the dewatering section, and gradually becomes smaller with the filter seam and screw pitch during the working process. , and the great internal pressure generated by the resistance of the pressing plate, the capacity is continuously reduced, thus truly realizing the purpose of dehydration. The screw stacker has a wide range of applications and is suitable for the advantages of high and low concentration sludge dewatering.

5) Decanter centrifuge sludge dewatering equipment: The process flow of the dewatering equipment can be roughly divided into: the pump lifts the sludge and then performs a screening pretreatment system, and then adds an appropriate amount of flocculant to the sludge to fully stir, and finally uses Centrifuges perform deep dehydration procedures. The dry and solid mud cake after sludge dewatering can be transported to other places where it needs to be reused, which truly achieves the double harvest of environmental protection, energy saving and economic value. The advantages of this equipment are convenient and simple operation, large processing energy, small processing site occupation, high degree of automation, and low noise due to low vibration.

6) Diaphragm filter press sludge dewatering equipment: The sludge dewatering process of this equipment can be roughly divided into: the sludge lifted by the pump enters the primary sedimentation tank and the secondary sedimentation tank, and then continues to enter the grid and concentration tank Then, a certain amount of flocculant is added for complete stirring and mixing, and then it enters the homogenization tank. Finally, it is highly dehydrated by the filter press, and the treated filter cake realizes the resource utilization of external transportation. The advantages of diaphragm filter press are high compression pressure, large processing capacity, low moisture content of filter cake, stable equipment performance, low failure rate and high degree of automation.

7).Geotechnical pipe belt sludge dewatering equipment: The process flow is roughly as follows: first, the sludge is filled into the geotechnical pipe belt for many times through a mud pump, and an appropriate amount of flocculant is added to promote the solid-liquid dewatering effect of the sludge. The combination of the filter part of the pipe bag and the two power factors of the liquid pressure will quickly and efficiently dehydrate the added dewatering agent sludge, and the solid part of the dewatered sludge will be trapped in the geotechnical pipe belt, and the percolating water will be discharged to the river after treatment. in the waterway or directly into the municipal sewage pipe. The solid portion trapped in the pipe can be reused in other industries for efficient resource utilization. Its advantages are good anti-wear performance, good UV resistance and water permeability. The geotechnical tube bag has a strong accommodation capacity for sludge, a large volume adjustment range, and a civilized and hygienic working environment. It is suitable for projects with large amount of sludge dewatering, large construction site and relatively loose construction period.

Decanter centrifuge is a commonly used drilling mud processing equipment

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.
