Decanter Centrifuge – Operation and Maintenance

Decanter Centrifuge

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.
