The traditional Oil-based Mud Treatment Technology is recycling and incineration.,simple processing and low cost. But this measures is higher demands on stratigraphy and the incineration can cause serious pollution to the environment, Not conducive to the construction of environmental conservation-minded society. At present, to meet emissions requirements, The mainly measures is through physical or chemical method to separate oil from the oil-based mud.
Incineration is that putting the cuttings waste of oil-based mud into a pyrolysis incineration device to achieve decomposed at high temperature and deep oxidation. In the process of incineration, consumed the oil in the cuttings and reduced the oil content greatly. But This method can produce a lot of smoke during burns, and it is also expensive to process.
Heat treatment method is that puting oil-based mud into the distillation column and rotaring evaporator to achieve full heating, then cooling collection until most of liquid oil and water evaporative. and discharge directly after the drill cuttings meet emission standards of oil content. But this method of processing costs is very higher. It is estimated that disposal drilling cuttings of one well need the total cost about $330,000.
Centrifugal separation is that using the principle of centrifugal to separate oil from oil-based mud. That is the specialized centrifugal separation equipment. It is vertical cuttings dryer. After centrifugal treatment, Water-based mud and composite mud: Water content 8-10%, oil-based mud: water content≤6%, OOC≤3%. and this equipment is the environmental and low cost treatment method. so it is the most popular measure to disposal oil-based mud.
In the production process, there are different process requirements such as dehydration, clarification, concentration, classification and separation. The essence of dehydration and clarification is to separate the solid and liquid in the suspension from each other. Dehydration is to remove the liquid phase in the solid phase, and clarification is to remove the solid phase in the liquid phase.(Decanter Centrifuge)
A large amount of liquid phase, a small amount of solid phase, and the particle size of solid phase is very small (1o μ M) or amorphous mycelium, horizontal screw disc or tubular centrifuge can be selected. If the solid content is less than 1% and the particle size is less than 5rm, the tube type or zigzag type manual slag discharge can be used to separate vanadium. If solid content ≤ 3%, particle size < 5 μ m. Disc piston slag separator can be selected. The separation factor of tubular separator is high (f ≥ 1000, the separable particle size is about 0.5m. The finer particles have higher clarity, but the single processing capacity is small.
KOSUN is a professional manufacturer of Decanter Centrifuge for about 30 years, and we can supply capability of manufacturing decanter with bowl size from 220mm to 760mm.
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.
A machine running on a centrifugal force to separate different parts is called a centrifuge. Dehydrator Centrifuge is a common device that is usually found on oil or gas drilling sites.
Dewatering machine Centrifuge for oil and gas drilling machine, basically used to dilute the underground liquid and liquid. The main task of the settling centrifuge is to rotate the drilling fluid, thereby destroying the concentration of these fluids. The overall job function of anything is very complicated.
Centrifugal force is the body in the high-speed rotation by the power. They are commonly used to separate components of different densities, such as water and solids. Decanter centrifuge is a special type of centrifuge that separates
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.
