Kosun- Solids Control Company/ Drilling Waste Management Company
Solids control is a technique used in the drilling rigs to separate the solids crushed by the drill bits that are brought to the well surface. When unwanted solids are efficiently removed from the circulation system, the fluids in the wells are of highest quality. Efficient Solids Control results into less replacement of fluids, less waste and few additives that are needed to be removed and disposed. This also significantly decreases the risk of downhole related problems due to excessive solid contents in the drilling fluid.
Normally, solids control system contains five stages: the mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge. The shale shaker is used to separate big solids with diameter above 75μm, the desander addresses solids from 45-74μm, and the desilter segregates solids between 15-44μm. Sometimes the desander and desilter are combined as one high efficiency mud cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. When there is no air in the mud, the degasser works as a big agitator. All these stages are mounted on the top of the mud tank. After separating the solids, the clean mud can be pumped into the borehole again.
Recent advances in solids control include the creation of a closed loop system which allows for increased environmental control and reduction in the potential for spills of drilling fluids. Several US states have either passed or are considering the implementation of closed loop systems, particularly for hydro-fracturing operations.
KOSUN solids controlsystem includes shale shaker, decanter centrifuge, desander, desilter, vacuum degasser, sand pump, agitator and mud tank, and horizontal decanter centrifuge and disc centrifuge.
Just as we all know that Decanter Centrifuge is one kind of machine revolving at high speed. During operation, revolving drum will generate strong centrifugal force (it is not like the solid control system, to some extent, decanter centrifuge is a core part for a whole solid control system and water based mud unit). To ensure the safety of operators and equipment, the following safety rules shall be strictly followed when using it.
Pay more attention for original Instruction Orders or Steps. Through dynamic balance of revolving drum parts of centrifuge, during assembly, original installation order shall not be changed and there shall be no parts omitted. Threaded connection part shall be installed in place; during assembly, if there is assembly mark, the mark shall be aligned. Before startup, operating pump system shall be inspected and there shall be no water leakage under close state of magnetic valve.
Keep the decanter centrifuge off. Before clamping revolving drum clamp ring and fixing inlet/outlet device and other fastening screws, decanter centrifuge shall not be started.
Before completely stopping revolving drum, any part of equipment shall not be loosened.
During operation, if abnormal vibration of decanter centrifuge is found, power shall be cut off for emergency shutdown. After revolving drum is completely stopped, each part shall be disassembled cleaned and inspected and attention shall be paid to assembly order and position. After the causes of abnormal vibration are found out and removed, reassembly and startup can be carried out. Time interval between re-startup and shutdown shall be more than 4h (This item is also suitable for mud cleaner).
Flame heating or repair welding of main revolving drum parts is not allowed, especially revolving drum body, revolving drum cover and clamp ring.
Use of revolving drum parts and revolving drum parts of other equipment shall not be mixed, even the revolving drum parts with same model.
The above 6 tips or we can call it as steps should be kept in our mind, they can help us improve our working efficiency.

In the oilfield drilling industry, drilled solids within the drilling fluid must be removed in order to allow re-use of the drilling fluid. Efficient removal of these drilled solids results in considerable cost savings to energy companies through proper Oilfield Solids Control, reducing the treatment cost of drilling fluid, as well as protecting against catastrophic downhole tool damage and failures.
KOSUN Industries centrifuge is designed to remove the drilled solids from the drilling fluid, which allow for:
-Increased penetration rates
-Minimal drilled solids concentration
-Substantial cost savings through reduced drilling fluid maintenance, disposal costs and downhole tool protection.
-Separation of environmental and oilfield drilling fluids allowing for less environmental impact.
KOSUN has the experience that is required to design custom tailored strip sites for various applications.We understand that each application is unique and has different variables. By doing an engineering design we are able to identify target process rates, fluid parameters into and out of the site, surface equipment size restraints and deliver our clients with custom packages to suit their specific needs.

Decanter centrifuges for sale utilize centrifugal force to speed the dewatering or thickening of slurries and suspensions in many industrial and commercial applications. While these centrifuges, like others, may also be used to separate liquids from liquids, they are more applicable in situations that require the separation of liquids from appreciable amounts of suspended solids.
Food and beverage, water treatment, oil, gas and pharmaceutical industries commonly employ decanter centrifuges for the classification of solids based on the sedimentation principle as well as the clarification of fluids resulting from the settling out of debris. Other industrial uses for decantation include solids recovery which enables many manufacturing facilities to recover and reuse valuable materials that would otherwise be disposed of along with wastewater.
While gravity alone is sometimes used, decanter centrifuges are essential in applications where the density difference of elements within a heterogeneous mixture is too small or the particles themselves are too small. Whereas normal gravity could take ages to sort these materials, the centrifugal force generated by industrial centrifuges speeds the process while producing drier solids. Dryness is important as both dewatering and drying materials helps to provide raw or processed substances that are lighter in weight than their immersed counterparts making for easier handling and lower transportation costs.
The operation of a decanter centrifuge can be either batch or continuous and is not altogether dissimilar to other types of centrifuges. A metal or plastic cylinder fixed along a central axis houses the materials or solutions to be sorted. When a motor engages the axis perpendicular to this, it creates a rotational movement capable of creating gravitational pulls up to twenty thousand times that of normal gravity. This causes larger particles to separate out first in a radial direction allowing them to move toward the bottom of the cylinder while lighter materials move toward the top.
In some decanter centrifuges a mesh is used to collect solids with liquids passing through to the outer area of the cylinder before being drained. In other models a helical extraction screw directs solids to one end and liquids to the other. If high enough acceleration is reached, the solids may even become compressed for easy removal. Both new and used centrifuges are available to purchase. As adjustable and fixed acceleration models are widely available, it is important to consider the parameters of a specific application before purchasing a decanter centrifuge. Capacity should also be considered with regard to the intended use as should the design and material construct of a decanter centrifuge as these materials must be compatible with both process liquids and solids to be sorted.
