Oilfield Mud Fluids Decanting Centrifuge

Nov. 23, 2009 - PRLog -- Decanting Centrifuges are used to process unweighted and weighted, water-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Centrifuges are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid

GN manufactures and markets a complete line of high-speed, variable-speed decanting centrifuges for handling drilling fluids. Ruggedly built for oilfield and industrial service, they are especially effective in meeting fluid-on-cuttings discharge requirements in environmentally sensitive areas. They also deliver high fluid recovery rates and efficient solids control to significantly reduce the operator’s total fluids cost and limit waste disposal volumes.

In weighted drilling fluid systems, decanting centrifuges recover as much as 95% of barite, which is returned to the active system, while also discarding finer, lower-gravity solids. In chemically enhanced dewatering systems, centrifuges significantly reduce liquid discharge volumes and appreciably enhance total solids control system efficiency.

Mechanical separation of solids from the mud system through the use of a centrifuge is a highly-effective means of maintaining proper mud weight and viscosity. When used in conjunction withother solids control equipment, centrifuges enable users to maintain the mud properties within the prescribed range as per the drilling program. Typically, centrifuges are the final processing units in the arrangement of solids controlequipment. They are preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud conditioners (if utilized), degassers and hyrdocyclones.

LW series is a normal decanting centrifuge mode of our company,they are ideal choices for separating particles in drilling mud. 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 nud 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 are effective for separation
