Decanter Centrifuge Defined Meaning

Decanter Centrifuge

Introduction: Modern gas and oil drilling sites are just a rigid manifestation of multi layered complex mechanism. Several gigantic equipments are set and operated in a single oil or gas drilling sites. The mechanisms of these equipments are very complex and very subtle. A very common equipment that is seen in an oil and gas drilling site is a decanter centrifuge.

A decanter centrifuge is a very useful equipment for any drilling site. Here in this article, we will try to provide a brief description about what a  really it is.

A brief description of a decanter centrifuges: A decanter centrifuge is a device that can create a very fast rotation that 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.

There are three basic designs of decanter centrifuges:

The first one is vertically oriented decanter centrifuges.
The second one is horizontally oriented decanter centrifuges.
The third one is conveyor or scroll decanter centrifuges.

In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically. Vertical decanter centrifuges are very effective for high temperature and high pressure work. A horizontally oriented decanter centrifuges 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.

solid components from liquids such as drilling waste.

It plays an important role in waste water treatment, chemical industry and food processing. The performance of the settling centrifuge depends on several different factors.
Most of the drilling and handling equipment handling components of the mixture. It is necessary to separate them separately for further processing.

Three types of decanter centrifuges are used in the industry: horizontal, vertical and conveyor. It is basically a high-speed rotating bowl that separates the solid from the liquid matrix. In the case of a drilling industry, inputs are drilling waste.

Centrifuges are easy to install and require less maintenance. Even if skilled operators need to operate them, decanter centrifuges help save a lot of money and improve the overall efficiency of the industry.

Centrifuge provides more flexibility and better feedback mechanisms. This allows the operator to allow the machine to work under different settings to separate the different components. The space required to set up the machine is very small, easy to start or close, allowing multiple units to work at once.

Decanter centrifuge is high cost equipment. It is imperative that it is maintained well, after all the economy of overall project will largely depend on such wise measures only.
Here we are outlining a few tips with respect to operation and maintenance of decanter centrifuges :
1. Preparing for start-up: Before starting the centrifuge check all electric control system and related components. Test the rotating belt manually for any glitch. Inspect the overall panel for any alarming signs.
2. Start the equipment: Most of the modern horizontal decanter centrifuge comes with touch panel now that have fairly user friendly command buttons. Using the touch panel, release relevant commands to bring the equipment to start.
3. Preventive procedure: Once you are done setting up the system, do not directly start feeding the system, let it run for 5 minutes, add water to clean the stuck or dried material.
4. Shutting down the equipment: Do not cut off the power all at once and bring the machine to a halt. Gradually slow down the feed and let the machine process the remaining material till it lasts. Repeat the washing and cleaning procedure.

Make sure that no manual handling is done while machine is operational as it may be very risky.

Decanter centrifuge equipment is used to serve the purpose. The equipment uses the centrifugal force to separate different materials for treatment.

Wherever there is a need to separate materials of different densities is involved, There are many types of centrifuges, decanter centrifuges , vertical centrifuge, etc.

Now building on this definition, we can imagine the vast application of such equipment in a variety of industrial scenarios, where different materials need to be separated. Let us pick oilfield drilling industry for an instance, where large volume of drilling waste is produced by the drilling process.

Not only the waste is harmful to the environment, if disposed directly without treatment, but it also contains large quantity of drilling fluid that needs to be extracted and restored. To accomplish this challenging task of separating the fluid, decanter centrifuges are deployed in drilling operations.

The working of a centrifuge could be understood as – If laid down in plain words – it uses the express rotation to separate different types of materials. In a more technical expression, a centrifuge is the equipment that uses the centrifugal force to separate substance based on their density using the principle of sedimentation.

Imagine a jar full of milk cream, when churned at good speed, it separates the cream into butter and skimmed milk. We know that different materials have different density, and the centrifugal force makes them move against the axis of the pit in which they are stored with the help of rapid rotations using mechanical force. Naturally the material with lowest density will make it way upward and the one with highest density will get settled at the bottom of the pit.

The centrifuge equipment is used in a variety of machines that need to filter the mixture of solids and fluids. It finds it application in number of industries ranging from food processing industry to oil and natural gas industry.

Drilling Decanter Centrifuge Meaning Introduction

Drilling Decanter Centrifuge

Drilling decanter centrifuge is equipment used to separate solids and fluid from a mixture using centrifugal force. Centrifugal force is a force, arising from the body’s inertia.

Drilling Decanter centrifuge technique replaces the conventional method of settling down the solids in the process of water treatment and likes. The technique makes the process faster and improves the quality of the output at the same time.

If understood in the context of drilling industry, the solid control system to treat the drilling waste , decanter centrifuge is applied.

The drilling waste largely consists of drill cuttings and drilling fluids that are commonly called as drilling mud. Drilling cuttings are nothing but the rock shavings acquired during the borehole drilling process and the drilling mud is a mixture of chemicals that aids the drilling process by keeping the drilling bit cool and lubricated during the process of drilling.

Other than petrochemical industry the Decanter centrifuge has its application in number of other industries as well, e.g. food processing,  waste water treatment, fish processing, chemical, mineral processing, organic chemicals, polymer and inorganic chemical industry to name a few.

Due to its wide popularity across different industries, a decanter centrifuge is available in various types and variety of designs.  A few notable ones being – vertical orientation, horizontal orientation and conveyer or scroll type. Operators will be using their discretion to choose the appropriate type and design as per the application need, as that remains customizable.

The performance of same design and type of decanter centrifuge may also differ in two industries, as the performance will largely depend upon number of external factors, chief among them will be the type of the waste material they will be treating with. As the guiding principle of a centrifuge is the separation of fluid by buoyancy of the material it works on to separate.

Drilling Decanter Centrifuge Work Principles of Kosun

Drilling Decanter Centrifuge

Drilling Decanter Centrifuge operates on the principle of centrifugal force. It is based on separation of material via buoyancy. The centrifugal force is applied for accelerated settling of solids by increasing g-force.

So a lot of components get covered in the working of a decanter centrifuge – g-force, accelerated centrifugal force, viscosity of fluid in which solids are submerged, speed of conveyers, density of different matters, feed rate, etc.

drilling-decanter -centrifuge

Drilling Decanter Centrifuge  applied in solid control system of an oilfield drilling operation would typically be the last phase equipment in the process. The equipment will create high degree centrifugal force in the bowl to separate drilling fluid from the drilling waste .

The centrifugal force created by the centrifuge will contribute in this separation and the solid thus obtained will be carried through a conveyer that’s running at a different speed than the bowl, for further discharge. The g-force applied to the bowl will be anywhere between 1000 Gs to 4000 Gs.

The material to be filtered will be fed to the decanter centrifuge at a certain rate or speed, the bowl in which they are carried, will be set to rotate at a certain rate and inside the bowl, the conveyer will be running at different/slower speed to carry of the solids. The rotations will generate centrifugal force inside the bowl that will force the drilling cutting to settle out and the fluid or mud will be collected in the center of the bowl for discharge.

As we know the actual output will greatly vary depending upon the earlier mentioned aspects, different designs and types will use different dimensions. The size of the decanter or the diameter, rotation per minute, limit of g-force, density of material, rate of feeding the material, and the differential speed of conveyer to carry separated solid for discharge. All of these factors could be manipulated to achieve the desired output from the decanter centrifuge equipment. Another factor is for how long the material was stored or kept inside the bowl.

Horizontal Decanter Centrifuge of Kosun Equipment Work Principle

Horizontal Decanter Centrifuge

Horizontal Decanter Centrifuge is a machine widely used in major industries to separate solid particles in a liquid. It rotates a very high speed creating the centrifugal force which causes the particles with higher density to move downwards and accumulate at the base. The movement speed is much higher than it would be under a normal gravitational force.

Horizontal Decanter Centrifuge machine has a base, a rotating tube that is vertical to the base and two vials that at fixed by the centrifuge arms to the rotating tube. The centrifuge arms are fixed on the top of the tube that rotates and hence can move upright at 90. On spinning of the tube, the materials are pulled by the centrifugal force into the vials towards the center.

The inertia of higher density components is also higher so they respond less to the centrifugal force. This lets them outward and the lesser density component are pulled inwards. This process leads to the separation of mixture of different components.

Carl de Laval, a Swedish Engineer had invented the centrifuge in 1883. He used it to isolate the cream from milk.  In 1920, Theodor Svedberg, also a Swedish Engineer further worked on Carl de Laval’s experiment and improved upon it. He created the ultracentrifuge that is used to separate the tiny particles of same weight. The vials are not very big in diameter in a ultracentrifuge.

In different industries the centrifuges used are rotated on different ranges between 1000 and 15000 rpm. In some other scientific applications the rotation is on a very high rate that can create a force of more than 25000 times as that of gravity.

The University of Colarado also invented a super-centrifuge. This is used to test effects of explosions on building.

The centrifuge invented by Laval is used for separating the impurities like water from oil, waste-water treatment to purify the water.
