Decanter Centrifuge

Just as we all know that Decanter Centrifuge is one kind of machine revolving at high speed. During operation, revolving drum will generate strong centrifugal force (it is not like the solid control system, to some extent, decanter centrifuge is a core part for a whole solid control system and water based mud unit). To ensure the safety of operators and equipment, the following safety rules shall be strictly followed when using it.

  1. Pay more attention for original Instruction Orders or Steps. Through dynamic balance of revolving drum parts of centrifuge, during assembly, original installation order shall not be changed and there shall be no parts omitted. Threaded connection part shall be installed in place; during assembly, if there is assembly mark, the mark shall be aligned. Before startup, operating pump system shall be inspected and there shall be no water leakage under close state of magnetic valve.
  2. Keep the decanter centrifuge off. Before clamping revolving drum clamp ring and fixing inlet/outlet device and other fastening screws, decanter centrifuge shall not be started.
  3. Before completely stopping revolving drum, any part of equipment shall not be loosened.
  4. During operation, if abnormal vibration of decanter centrifuge is found, power shall be cut off for emergency shutdown. After revolving drum is completely stopped, each part shall be disassembled cleaned and inspected and attention shall be paid to assembly order and position. After the causes of abnormal vibration are found out and removed, reassembly and startup can be carried out. Time interval between re-startup and shutdown shall be more than 4h (This item is also suitable for mud cleaner).
  5. Flame heating or repair welding of main revolving drum parts is not allowed, especially revolving drum body, revolving drum cover and clamp ring.
  6. Use of revolving drum parts and revolving drum parts of other equipment shall not be mixed, even the revolving drum parts with same model.

The above 6 tips or we can call it as steps should be kept in our mind, they can help us improve our working efficiency. Just as I mentioned in the post, you could find more information about solids control system, drilling waste management unit, oil recovery unit, and some other solids control equipment, such as mud cleaner, sand pump, vacuum degasser, cutting dryer, etc. In another words, KOSUN could be your better cooperator.

Operating and maintaining process of decanter centrifuge

decanter centrifuge is a very useful equipment for any drilling site. A decanter centrifuge is basically used to dilute the fluid that is extracted from the gas or oil mine. Generally, the liquid that is extracted from a mine is of highly concentrated and coagulated. So, extracting minerals from them is practically impossible.  In order to thin up the extracted fluids, a decanter centrifuge is used. By using the rotational speed of a decanter centrifuge, the highly concentrated are turned into minerals extractable thin liquid.

Decanter Centrifuge

There are three basic designs of decanter centrifuges. The first one is vertically oriented decanter centrifuge, the second one is horizontally oriented decanter centrifuge and finally the third one is conveyor or scroll decanter centrifuge. In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically.

Vertical decanter centrifuge is very effective for high temperature and high pressure work. A horizontally oriented decanter centrifuge gathers the fluids or solids generated from high rotation in horizontal orientation. A horizontally oriented decanter is very effective for high pressure works as it provides a strong organization due to its horizontal orientation. Lastly, a conveyor or scroll centrifuge is basically a rotating machine inside a bowl.

The operating and maintaining process of a decanter centrifuge:

The first thing that should be done to maintain a decanter centrifuge is to replace any hydraulic suction filter and replace hydraulic returns filter. It is a very important step for the oil and gas drillers. As when the oil or gas drilling goes on both the hydraulic suction filter and the hydraulic returns filter undergo an extensive pressure.  So, there is a huge possibility of both of them to be worn out. So in that sense, both of the filters must be checked regularly and be replaced when it is necessary.

Another important thing that is required to do in order to maintain a decanter centrifuge is greasing the machine.  It is very important. As decanter centrifuge is basically used in a heavy working areas, the machine can easily be stuck or jammed off. In order to avoid that, greasing is very important. Oil lubricated gear box greasing and recirculating oil greasing are two very effective methods for greasing. A very significant task for managing a decanter centrifuge is adjusting speed sensor to it. It is very important just because adjusting a speed sensor enables drillers to control the differential speed.

Beside these above mentioned activities replacing hydraulic motor sensor, bowl belt replacement, scroll belt replacement and regulating the weir plate are some of the steps that should be taken to maintain a decanter centrifuge.

The Operation of a Decanter Centrifuge

The operation of a decanter centrifuge can be either batch or continuous and is not altogether dissimilar to other types of centrifuges. A metal or plastic cylinder fixed along a central axis houses the materials or solutions to be sorted. When a motor engages the axis perpendicular to this, it creates a rotational movement capable of creating gravitational pulls up to twenty thousand times that of normal gravity. This causes larger particles to separate out first in a radial direction allowing them to move toward the bottom of the cylinder while lighter materials move toward the top.

Decanter Centrifuge

In some decanter centrifuges a mesh is used to collect solids with liquids passing through to the outer area of the cylinder before being drained. In other models a helical extraction screw directs solids to one end and liquids to the other. If high enough acceleration is reached, the solids may even become compressed for easy removal. Both new and used centrifuges are available to purchase. As adjustable and fixed acceleration models are widely available, it is important to consider the parameters of a specific application before purchasing a decanter centrifuge. Capacity should also be considered with regard to the intended use as should the design and material construct of a decanter centrifuge as these materials must be compatible with both process liquids and solids to be sorted.

Decanter centrifuges utilize centrifugal force to speed the dewatering or thickening of slurries and suspensions in many industrial and commercial applications. While these centrifuges, like others, may also be used to separate liquids from liquids, they are more applicable in situations that require the separation of liquids from appreciable amounts of suspended solids.

Food and beverage, water treatment, oil, gas and pharmaceutical industries commonly employ decanter centrifuges for the classification of solids based on the sedimentation principle as well as the clarification of fluids resulting from the settling out of debris. Other industrial uses for decantation include solids recovery which enables many manufacturing facilities to recover and reuse valuable materials that would otherwise be disposed of along with wastewater.

While gravity alone is sometimes used, decanter centrifuges are essential in applications where the density difference of elements within a heterogeneous mixture is too small or the particles themselves are too small. Whereas normal gravity could take ages to sort these materials, the centrifugal force generated by industrial centrifuges speeds the process while producing drier solids. Dryness is important as both dewatering and drying materials helps to provide raw or processed substances that are lighter in weight than their immersed counterparts making for easier handling and lower transportation costs.

Kosun Decanter Centrifuge Working Principle

To fully understand Kosun Decanter Centrifuge Working Principle, we first define what is decanter centrifuge. A decanter centrifuge is a device that can create a very fast rotation. A decanter centrifuge is basically used to dilute the fluid that is extracted from the gas or oil mine.

Decanter Centrifuge Working Principle

There are several types of decanter centrifuges currently utilized in the industry, the most common of which are vertical decanter centrifuge, horizontal decanter centrifuge and conveyor decanter centrifuge. The principle behind a decanter centrifuge is based on the theory of gravitational separation. For example, if you fill a glass with a mixture of mud and water, over time the weight of the mud will cause it to settle down at the base of the glass. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two.

A decanter centrifuge employs the same principles of gravitational force. However, unlike the glass mixture, the process is expedited through the use of continuous rotation. In fact, rotation provides anywhere from 1000 to 4000 times the normal gravitational force, reducing the time required for separation from hours to seconds.

The concept of rotational separation is similar to rides found at amusement parks and county fairgrounds. In these rides, placing yourself at an angle allows you to overcome the gravitational forces induced by rotation. Similarly, a decanter centrifuge is essentially a bowl tube that rotates at an extremely high speed. The bowl tube is equipped with an internal conveyor which moves in the same direction but at a different velocity.

Step 1: The slurry is inserted into the centrifuge through a connecting pipe and onto a conveyor.

Step 2: Utilizing an internal feed compartment, the conveyor ushers the slurry through a nozzle into the bowl area.

Step 3: The bowl rotates at high speeds to induce gravitational forces.

Step 4: High speed rotation separates the solid material from the liquid in a matter of seconds.

Step 5: The conveyor delivers the solid material upwards where it is discharged through a nozzle.

Step 6: The solid material removed, the purified liquid is released from a separate output.

3 Phase Decanter Centrifuge in Oil Recovery Unit

3 Phase Decanter Centrifuge(Three-phase Decanter Centrifuge) is also called Tri-canter centrifuge, it is commonly used in oil drilling work to separate the oil rate from drilling solids, it belongs decanter centrifuge series. In Oil Recovery Unit project, 3 Phase Decanter Centrifuge is the core solid control equipment in the whole system. Today we will share more information about 3 Phase Decanter Centrifuge.

3 Phase Decanter Centrifuge

Just as we all know that decanter centrifuge is the main equipment for a whole solid control system, even in the drilling waste management unit, we also need a VFD decanter centrifuge (of course, cutting dryer is also the core part one on drilling waste management, while mud cleaner is the important equipment in solid control system), both system should be worked with drilling mud tank, that is to say, the whole equipment should be mounted in the mud tank. 3 Phase Decanter Centrifuge is the core one for the whole oil recovery unit.

You will find necessary information about oil recovery unit in last post. We did not mention the 3 Phase Decanter Centrifuge in that post. In our design, 3 Phase Decanter Centrifuge is a kind of solid control equipment used to separate the mud, water and oil from the drilling solids. Comparing with traditional decanter centrifuge, the most important function of the three-phase decanter centrifuge is that it could separate the oil from the drilling solids, while the traditional one just could separate the mud and water.

Generally speaking, 3 Phase Decanter Centrifuge is always used in huge solid control system or the system like Oil Recovery Unit. The common feature of these units is they are huge and complicated. At the same time, because of the high technology needs and heavy difficult for design and manufacture, 3 Phase Decanter Centrifuge is the one with blooming and splendid.

Why decanter centrifuge is indispensable in drilling operation?

Before hydrocyclones (desanders and desilters) and decanter centrifuge became available for drilling applications, shale shakers and dilution were the only means of solids control of drilling fluids. Consequently, solids too fine to be separated by the shaker screens in use could be controlled only by dilution which was a costly procedure that generated large quantities of excess drilling fluid. Decanter centrifuge was designed to remove the fine cut and at the same time reduce the drilling cost.

The work principle of decanter centrifuge:Centrifuges, like shale shakers and hydrocyclones, are solids control equipment, It achieves the separation goal by dividing the fluid into highdensity and lowdensity streams to separate one from the other. The processing is achieved by accelerated sedimentation. As the drilling fluid passing through a rapidly rotating bowl, centrifugal force moves the heavier particles to the bowl wall, where they are scraped toward the underflow discharge ports by a concentric auger, also called a scroll or conveyor, which rotates at a slightly slower rate than the bowl. The separation of the heavier particles divides the processed fluid into two streams: the heavy phase, also called the underflow or cake; and the lighter phase, which is called the overflow, light slurry or centrate. The heavy phase will be discarded while the lighter one will be returned to the mud tank to be further treated. The removal of these solids in order to control rheology and filter cake quality is the primary reason for centrifuging weighted drilling fluids. When the finest solids are not removed, the only alternative means of reducing their concentration is dilution, always an expensive process.

Features of KOSUN LW serious decanter centrifuge 

  1. Innovative design includes longer bowl for increased retention time, resulting in drier solids and finer cut points
  2. Big bowl Big Volume, high G force available
  3. Stainless steel bowl, scroll, compartment and cover resist corrosion and provide long service life.
  4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
  5. German FAG or Sweden SKF brand bearings
  6. Electrical Components: SIEMENS/Schneider ATEX or IEC Ex for option.
  7. Screw pump & centrifugal pump feeding pump option available to meet different application.

To meet the requirements of the development of modern drilling engineering, KOSUN developed and equipped with the explosionproof variable frequency control system which could adjust separation factor and drum rotational speed.By this new technology,make the centrifuge to adapt property changing of mud duringthe operation process,that make the treatment more effective and perfect.
