How does Decanter Centrifuge Work?

Decanter Centrifuge

Introduction: Decanter centrifuge is a very common equipment that is often found in an oil or gas drilling site. A decanter centrifuge is a very important machine for oil and gas drillers. A decanter centrifuge is basically used to dilute the underground fluids and liquids.

The main job of a decanter centrifuge is to rotate the drilling fluids and in doing so breaking the concentration of those fluids. The whole working functions of any decanter centrifuges is pretty much complex. Here is a discussion given below about how a decanter centrifuge works.

The way a decanter centrifuge works:  As it is mentioned before the process of a decanter centrifuge is a bit complex. Usually,  decanter centrifuges depend on sedimentation, differential speed and G force to perform its job. A decanter centrifuge needs a centrifugal force in order to loosen the fluid.

The sedimentation rate is an important feature for the centrifugal process. If the G force or centrifugal force is very high, the separation process becomes very easy and effective. The size and shape of particles and their level of concentration determine the sedimentation rate of any decanter centrifuge.

The sedimentation rate also depends on the centrifugal force. Another important issue for the functionality of decanter centrifuges is the differential speeds. In a centrifuge two different parts rotate simultaneously. The first part that rotates is the exterior bowl and the second part that rotates is scroll conveyor. Sedimentation is gathered in the centrifugal cylinder as the result of varying speed of the two above mentioned separate parts.

If the differential speed of decanter centrifuges is too high, a little time is required to loosen up the concentration of waste fluids. So, it is very important to keep the differential speed of a decanter centrifuge minimal. Thus, a decanter centrifuge operates its functionalities.

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.

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.

When it comes to solid control equipments, this is no exception. A few careful measures go a long way to ensure that the operators will find the equipment reciprocating their care for them.
The first and foremost one in this aspect is the preventive maintenance of the equipment. The decanter centrifuge as such is low maintenance equipment and has a high capacity of handling the drilling waste treatment , but that should not mean for the operators to simply overlook the state of operation of the equipment.

A very common mistake committed by the operators is the continuous use of equipment without giving it rest and inspection for any wear. The moment any component is spotted showing any signs of wear, operators should consider fixing it, without just pushing it for further use, however small. As it goes with machinery, that all components work in sync, so even a worn out rubber could cause the breakdown of entire equipment. So watch out for any kind of wear or damage.

Another challenge faced by drilling industry in context of economic configuration decanter centrifugeis the lack of trained personnel or operators. With evolving technologies, decanter centrifuges have been made much more automated and need little operational attention. However, to maneuver the equipment to achieve the desired output, need of staffing appropriate personnel is of paramount importance.  With ever stringent health and safety regulations, rig operators struggle with their staffing needs.

The high turnover further adds to the problem. Finding the qualified and experienced operators and investing time in resources in training them to bring the up to speed is a very big challenge for project managers.

The standard of working of a decanter centrifuge is based on gravitational force. The component with higher density settles at the base and the lighter density component suspends above.

Economic Configuration Decanter Centrifuge is used in different industries like the oil, food processing and chemical. It is an important device in all the industries. The decanter centrifuge are used to separate mixtures of liquid, solid-liquid, dewatering and in extracting of various components.

The different types of decanter centrifuge are vertical decanter centrifuge, horizontal decanter centrifuge, conveyor centrifuge. The principle on which the decanter centrifuge is based is the gravitational separation. Example: When a glass is filled with muddy water after sometime the mud will settle down at the base due to the gravity. One can see a clear separation between the mud and water.

In the principle of a decanter centrifuge the mixture is put in the centrifuge through a pipe and on a conveyor. The conveyor sends the muddy mixture into a bowl tube. This bowl tube then rotates at a very high speed to form gravitational force. The high rotation speed then isolates the solid from the liquid within few seconds. The solid material then moves upwards and is released through the nozzle. When the solid material is taken out, the distilled liquid is also discharged through a separate outlet.
