Three sets constant-frequency decanter centrifuge for ARAMCO

Usually decanter centrifuge is the third stage separation equipment of drilling fluid circulating system, it can separate out the solid particles whose diameter is 5-7um. Decanter centrifuges are an essential part gradually of cost drilling fluid processing.

Nowdays, DC solid control shipped three sets constant-frequency centrifuge for ARACO. I am glad that the company was introduced by my another Saudi clients. Finally we build our first business cooperation because of this relationship.


Features of the orders’ centrifuge:

1. The three sets centrifuge with bowl diameter larger than 450mm is always called as big bowl. Comparing with the small bowl centrifuge of 842 inch, the big bowl has larger capacity.
2. The protection of the screw propeller is tungsten carbide tiles to enhance the anti-wear features. Long lifetime saves the cost for repairing and maintenance.
3. DC Solid control’s centrifuge, no matter big bowl or small bowl, is driven by 2 motors. This 450mm big bowl is driven by a 30kw main motor and a 7.5kw back motor. Via the planetary gearbox, the back motor could drive the screw propeller to rotate same direction as the bowl but different speed, so that the solids could be pushed out from the inside the bowl.

decanter centrifuge

In addition to producing the constant and variable frequency 2 phase decanter centrifuge. DC Solid control aslo manufacture the three phase decanter centrifuges to separate the oil,water and cuttings from drilling fluid. If you have requirements of any of them, please don’t hesitate to contact us.

3-Phase horizontal centrifuge China supplier

The 3-Phase Separating Decanter is a centrifuge in which two liquids of different densities are separated from each other. At the same time solids are separated and discharged. 3-Phase centrifuges are widely used in oilfield at present.

A three-phase centrifuge is capable of three distinct phase separations in a single pass. Three-phase centrifuges are uncommon in the petroleum industry, but have been used in other industries. The oil field separation is a far more difficult problem, because the oil field mixture is a solid-stabilized emulsion produced from a liquid-solid. This 3-phase separation horizontal decanter centrifuge is primarilly employed for solid-liquid-liquid separation, namely the simultaneous separation of one solid phase and two immiscible liquid phases with different densities. The premise is that the solid phase is the heaviest.

3-phase centrifuge

Separation process of 3-phase centrifuges 

The feedstock enters the decanter through feed tube and flows into the centrifugation space through the distributor. The conveyor screw transports the solids to the solids discharge. The level of the liquid can be adjusted by fitting regulating rings or disks of the required inner diameter. Separation of the two liquid phases takes place in the separation zone, whereby the light phase flows towards the bowl axis, and the heavy phase towards the bowl wall.

Working principle

Under the centrifugal force, the material will be formed with three relatively stable layers including solid phase layer, as well as heavy and light liquid layers, from the bowl wall to the inside. The solid phase will be driven to the small end of the rotary bowl by the screw conveyor and then will be expelled from the slagging hole. The heavy and light liquid phases will flow towards the big end of the rotating bowl along passages among screw flights and then will be drained from different outlets. Therefore, the continous 3-phase separation achieved.

DC Machinery is a specialized 3-phase separation horizontal decanter centrifuge manufacturer and supplier in China. We offer a vast range of products, including high speed centrifuge, 2-phase separation horizontal decanter centrifuge. If you have any requirements, please contact us.
