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.
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.
Drilling Decanter Centrifuge that is a machine based on centrifugal operation to separate different components is called a centrifuge. Which is welcomed by domestic and foreign customers.
A settling centrifuge is a special type of centrifuge that separates solid components from liquids such as drilling waste . Centrifugal force is the force that the object experiences when rotating at high speed. They are commonly used to separate components of different densities, such as water and solids.
Sedimentation centrifuges play an important role in wastewater treatment, chemical and food processing. The performance of the settling centrifuge depends on several different factors.
Most of the drilling and treatment plants deal with the mixture of components. They must be separated for further processing.
The main three types of settling centrifuges are used in industry:
The settling centrifuge is essentially a bowl that is rotated at high speed to separate solids from the liquid matrix. In the case of a drilling industry, the input is a drilling waste .
Centrifuge is very easy to install and requires less maintenance. Even if skilled operators need to operate them, the decanter centrifuges help save a lot of money and improves 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 parts. The space required to install the machine is very small, easy to start or shut down, allowing multiple units to work at once.
Decanter centrifuge is not without restrictions. The machine will produce a lot of noise and vibration. It can not separate biological components and has high energy consumption. The initial cost of setting up the machine is quite high. The rotating parts are also prone to wear and tear over time.
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.
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.
