Drilling Decanter Centrifuge Good Performance by Kosun

Drilling Decanter Centrifuge

Drilling 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 decanter 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.

Decanter Centrifuge

Decanter centrifuge of drilling waste is the waste matter generated as a result of the very process of extraction of oil and gas from the earth, popularly known as drilling. This is an extensive and trillion dollar industry with a corresponding and gigantic waste production issue on a global scale. That is why; a new drilling waste management system called drilling waste management was introduced.

Decanter Centrifuge

It consists of a series of processes from collection, management and containment of waste to subsequent treatment and disposal. Over the years, many techniques and methods were introduced for an efficient management of drilling waste. Also quite recently we saw more advancement and mechanization being brought into the whole process.

As a result of this, now we have instruments like decanter centrifuge to aid to the separation and handling of drilling waste. So let’s understand more about them and their mode of operation.

As the name suggest, the equipment uses decanter centrifuge forces to aid to the separation of desired and waste matters taking advantage of their differences in densities and other properties.

The mixed substance obtained from extraction is made to enter a disc or cone shaped structure that is rotated at a suitable speed. Because of the difference in natures of the unwanted and desired quantities, they are separated by combined effect of centrifugal and gravitational forces.

The fuel which is separated drops through the hole at the centre of the structure and the waste remaining in it is properly contained. For better gathering or collection of these waste matters, the walls of the discs are generally made with interspaces or slot like cavities.

The drilling waste progresses towards the walls of the disc and moves into a containment tank through the interspaces provided. As the machine consists of several moving parts, all components are to be kept smooth and clean to ensure optimum efficiency.

The main part of the drilling waste management system is the sedimentation centrifuge. Decanter Centrifuge is usually used for drilling waste treatment , mud and sludge and oil separation, etc.

There are some ways to maximize the performance of settling centrifuge:
• Operates with high G vibrating screens for water-based drilling waste or chips. After treating the waste with a vibrating screen, the material is fed into a settling centrifuge to separate small solid matter.
• Vertical cutting dryers are widely used in almost every borehole area. The use of decanter centrifuges and vertical dryer will help to deal with oil and synthetic drilling waste. The chips are first treated in a slurry shaker and then treated in a vertical dryer and then into a settling centrifuge.

• It is also important to choose the correct type of settling centrifuge. The details of the equipment must be discussed with the supplier and the manufacturer. Operators can understand the performance and efficiency by looking at machine data under similar conditions.
• The decanter centrifuge you choose must be based on your design. Some applications require high speed, while other applications require large bowl separation. Before purchasing the machine, please remember to summarize the clear picture in advance.
• The same model of the machine can also be slightly different in terms of feed technology, level and machine layout. Any change will seriously affect the performance of the machine.
• Last but not least, the machine should be operated by a professional operator. The dewatering machine requires a highly skilled operator’s function. A lot of things depend on the operator’s function. The main problem that most staff members suffer is the lack of skilled operators. So this aspect of the machine is as important as the rest.

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.

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.

decanter centrifuge

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.

What are the Principles of Decanter Centrifuge of Kosun

Decanter Centrifuge

Decanter centrifuge separates the solid material mixed with some liquids that contaminates the water and converts the mud into sludge. It is an important component utilized in petrochemical, food processing and oil industries. These industries will not be able to function in the absence of Centrifuge. The centrifugal force is created by the decanter centrifuge and creates the centrifugal force by rotation.

Operational & Functional Principles of decanter centrifuge:
•    The principle of decanter centrifuge is based on the theory of gravitational separation. A component with high density settles at the bottom and the component with lesser density suspends upwards.

The decanter centrifuges increases the rate at which the component settles increases due to the use of continuous rotation. This force is from 1000 to 4000 times than the normal gravitational force. This method of separation gives fast results.
Example: When a glass is filled with mud and water, after few minutes the mud will settle at the base of the glass due to its weight. Since the mud is settled at the base become solid, the water comes upward that creates a separation between the mud and water mixture.

This method of separation by rotation can be compared to that of rides of amusement parks. In the same way the decanter centrifuges basically a bowl tube rotates at a very high speed. The bowl tube has an internal conveyor that moves at different velocity but in the same direction.

The decanter centrifuge is ideal equipment for treating waste water. There are various industries where these types of machines are vital.

The 2-phase separation method is used for Waste water treatment, sludge de-watering, and also food processing.

The 3-phase separation process separates two liquids like water and oil, which have different densities and cannot be mixed together, are separated. This 3-phase separation produces edible oil, bio-diesel and oil sludge.

Decanter Centrifuge – Operation and Maintenance| Kosun Solid Control

Decanter Centrifuge

Decanter centrifuge is one of solid control equipment that  uses centrifugal force to aid to the separation of waste matter.

Drilling operations refers to the very process of extracting oil and gas from the earth for various commercial and industrial purposes. The industry is worth trillions of dollars today and is thus a very important part of any country’s development. In the past few decades, the demand for the products like gas and oil went up significantly. This led to a corresponding increase in the drilling activities all across the globe.

Like any other industrial activity, drilling too is bound to have some sort of waste produced as byproduct. This is termed as drilling waste and the term gained much popularity with the rising issues it caused to the environment. This in turn led to another class of waste management being introduced, known as drilling waste management. It involves several processes from maintenance, management and containment to subsequent handling and disposal of drilling waste promising better sustainability and conservation of environment.

In the various processes involves with drilling waste management , one important step is called waste maintenance. This was earlier done with conventional processes like settling and involves separation of the unwanted matter from the desired part and further storage and transportation. However, with advancements in technology and machinery, today the whole process id mechanized. The most popular equipment dedicated for the process is named decanter centrifuge .

As the name suggests, the machine uses centrifugal force to aid to the separation of waste matter. The machinery has a complicated design but with a very basic and simple concept. The mixed substance obtained directly from extraction is allowed to flow to a disc shaped structure. The disc is then rotated. This rotation calls the centrifugal and gravitational forces into action which facilitates the separation of drilling waste from the fuel. The fuel passes through the hole at the centre of the disk and the waste remaining in the structure is passed on for containment.

The equipment consists of moving parts and hence should be cleaned and kept smooth as possible to avoid reduction in efficiency. Also make sure to cut off the power to the machinery if it is to be dismantled for some purposes.

Decanter Centrifuge – Operation and Maintenance

Horizontal Decanter Centrifuge

Horizontal decanter centrifuge is driven by two motors. The main motor drives the drum and the housing of the differential through the belt, and the auxiliary motor drives the auger after the differential speed. This will cause the drum and the auger to rotate in the same direction with a certain differential.
