Decanter centrifuge is a important equipment in drilling fluid purification system

A centrifuge is a piece of equipment, generally driven by an electric motor (some older models were spun by hand), that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. A centrifuge is also used to separate the components of blood in blood banks. The centrifuge works using the sedimentation principle, where the centripetal acceleration causes denser substances to separate out along the radial direction (the bottom of the tube). By the same token lighter objects will tend to move to the top (of the tube; in the rotating picture, move to the center).

Decanter centrifuge is a important equipment in solid control system. It is widely used in drilling waste management system and oilfield mud circulation system. Decanting Centrifuge separate the suspending fluids using  the principle of centrifugal action, the suspending fluids is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder. Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the mud export of the small end of the drum and excreted. But the fluids is excreted from the overflow hole of the large end. Such cycle is in order to achieve the purpose of continuous separation.High speed decanting centrifuge is effective for separation 

Drilling Fluid Centrifuge Working Principle

Decanting centrifuge key part is screw, conveyor and transmission. When centrifuge work, drilling fluid will flow into centrifuge through drilling fluid input. Then the roll bowl will increase speed and fluid will flow into centrifuge through one fixed input pipe. Since rolling bowl rotate at rather high speed.

Drilling mud decanter centrifuges are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids.

KOSUN, as a professional solids control system manufacturer in China, obtains much experience in designing & manufacturing all these drilling mud recycling system, such as shale shaker, desander, desilter, vacuum degasser,mud cleaner,shear pump,centrifugal pump,decanter centrifuge, mud agitator,mud gun,mud tank,jet mud mixer,etc. and have exported to many countries & obtain good reputation with qualified products & superior service.

The application of oil drilling solids control decanter centrifuge

In the oilfield drilling, decanter centrifuge is used frequently and is necessary to effectively control solids particles in the drilling fluids. Decanter centrifuge is also called horizontal screw discharge sedimentation centrifuge, is the special solids control equipment of solid-liquid separation, designed by the characteristic of drilling fluid. It can accomplish each procedure of feed, centrifugal sedimentation, unloading, etc.

Decanter centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the spiral propeller rotate in the same direction with a certain differential speed. And when the material is fed into the inner canister of the spiral propeller from the feed pipe, the material will be flowing to the drum wall through material exit. The degree phase of the material is different because it is subjected to different centrifugal force and so, the material with heavy phase will be quickly accumulated onto the inner wall of drum while the material with light phase will slowly stick to the surface of heavy phase, a layer of interface to be formed between degree phases. And along with increase of heavy phase accumulation, the top end of spiral vanes will be inserted into the accumulated layer of heavy phase. By this step, the drum and spiral impeller are rotating with high speed in the same direction, having differential speed value to some extent. And the relative revolution difference is making grain of heavy phase move to the material exit on the small end while the liquid of light phase is forming into passage, flowing to the exit of liquid phase. The overflowing mouth position of liquid phase is controlled by the regulating plate.

Decanter centrifuge by KOSUN is widespread in North America, Europe, Middle East and so on. KOSUN decanter centrifuge is used in separating suspension of solid phase with particle diameter not less than 2μm for drilling mud and fluids handling.

Mud/gas separator is a necessary oil drilling security in solids for sale in Saudi Arabia

Mud/gas separator is the short name of drilling fluid and gas separator, is a special equipment of drilling gas-liquid separator for gas drilling fluid degassing. The difference of gas-liquid separator and degasser is the ability to clear away the big air bubbles in the fluid. The big air bubbles is the gas expansion in borehole, diameter is 3~25mm. This big bubble cause well kick, even kick out of the rotary table surface.
The degasser is used for little bubble removal, not for big. The gas-liquid separator can inlet the fluid from rotary blowout preventer or from the choke manifold, to separate the big bubble. The drilling fluid has small bubble after disposed, after through the shale shaker, it pass into the degasser for gas removal.

KOSUN gas-liquid separator is the professional equipment to process the gas cut drilling mud.The proportion and viscosity of the gas cut mud will emerge large deviation, it can not meet the requirement of drilling.

KOSUN drilling mud vacuum degasser usage in a solids controrl

Degasser is also called degassing pot, mainly used in degassing the fruit juice in vacuum to stop the oxidization and turning brown, at the same time, removing the gas attaching to the suspended particulates, stopping the particles upping, improving the looking, reducing bubbles in high temperature sterilizing and filling, and reducing the corrosion. Degasser can also be used in producing liquid milk, and beverage contenting milk. Normally, vacuum degassing is after homogenizing, and sometimes, is before filling. 

Vacuum degassers have more moving parts and higher initial cost. This is due primarily to the vacuum pump and attendant components. They are, however, much more efficient. Because gas volume is inversely proportional to pressure, gas bubbles surface from a fluid more rapidly under pressure. By combining impact and turbulence features with low pressure, modern vacuum degassers prove to be fast acting and highly effective in separating dissolved gasses.

Features & Benefits

1. Self contained unit without need for centrifugal pump to feed drilling mud.

2. Eliminate corrosion and reduce reparation and maintenance costs.

3. Short footprint,can be installed in smaller spaces.

4. Degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter.

Drilling fluid mud agitator is used in surface mud system in mud tank

A mud agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.

KOSUN uses an impeller to mix and suspend the solids using both axial and radial flows, and by utilizing low shear mixers to suspend and mix mud additives particle size degradation and polymer shear. Unlike centrifugal pumps or mud guns. KOSUN Mud Agitator is relatively low shear and low energy device, so it’s easy to operate and inexpensive to maintain. This will ensure that mud additives are homogeneously mixed to prevent dead spots. Agitators keep the active mud system flowing even when the pumps are disengaged and keep the weighting agents in suspension.This drilling fluid mud jet mixer is a high performance equipment worked together with the solids control system for petroleum drilling.This mud jet mixer is mainly used to configurate and increase the drilling fluid, change the fluid’s density, viscosity, and dehydration. The effect of SLH series Mud jet mixer is more prominent if it matches with Shear Pumps. It is safe and stable enough to be moved conveniently.

Except,KOSUN supplies other solids control equipments,including shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, submersible slurry pump, shear pump,mud agitator, mud gun, drilling fluid mud cleaner, decanter centrifuge, jet mud mixer, mud tank, diesel tank, water tank, etc.Complete solids control system including arctic solids control system,mobile solids control system,skid-mounted solid control system,etc.
