This is a how to article and discuss how to find a proper decanter centrifuge, basically two things need to be considered: economic expectations and technical requirements. It is essential to clearly define the process, and pass this information to the centrifuge supplier at initial briefings.
The prospective user should also clearly define exactly what the centrifugal process is required to achieve. Fluid charactor before and after treatement, density, viscosity, solids content etc.
The whole process in your plan, before and after centrifuge. Does the material require clarification, classifi cation, degritting, thickening, dewateri.rg, washing or separating and repulping, and is the process a solidliquid, liquid-liquid or a three phase liquid-liquid-so1id duty?
Once the process is clearly defined, it is easier to identify variables such as the percentage of suspended solids, volumetric slurry throughput, solids throughput and the required product consistency at discharge.
Other consideration like G force, pH, for different applications.
Particle size, distribution arrd shape are also important factors when determining separation capabilities ald whether or not a batch or continuous centrifuge is the best option. Generally, materials which are predominaltly 45 microns and above and relatively incompactable are suitable for separation by filtration equipment, whereas finer or compactable materials lend themselves more to separation by sedimentation.
Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge 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.
Mechanical separation of solids from the mud system through the use of a decanter centrifuge is a highly-effective means of maintaining proper mud weight and viscosity. When used in conjunction with other Solids control equipment, decanting centrifuge enable users to maintain the mud properties within the prescribed range as per the drilling program. Typically,oilfield decanting centrifuge is the final processing units in the arrangement of solids control equipment.
GN Solids Control manufactures different type of decanter centrifuges, from 9in to 72in, and widely used in oil gas industry, now moving into other industries also.
