Dewatering principle of decanter centrifuge

The decanter centrifuge uses the principle of centrifugal sedimentation to separate the drilling suspension. The suspension enters the drum from the feed pipe through the liquid outlet hole in the screw pusher, and the solid particles are pushed to the inner wall of the drum under the action of centrifugal force and pass through the screw. The blades on the pusher are pushed to the slag discharge port at the small end of the rotating drum, and the liquid phase overflows through the overflow hole at the big end of the rotating drum. Such continuous circulation, in order to achieve the purpose of continuous separation. Sedimentation centrifuges belong to the category of horizontal spiral centrifuges, and the full name is horizontal spiral sedimentation centrifuges. crown

Dewatering principle of the decanter centrifuge: The decanter centrifuge uses the density difference between the solid and liquid phases, and under the action of centrifugal force, accelerates the sedimentation speed of the solid phase particles to achieve solid-liquid separation. The specific separation process is that the sludge and the flocculant liquid are sent into the mixing chamber in the drum through the inlet pipe, where the mixing and flocculation are carried out (if the sludge pump is dosing before the pump or the pipe is behind the pump, the flocculation reaction has been advanced) Due to the high-speed rotation and frictional resistance of the rotor (screw and drum), the sludge is accelerated inside the rotor and forms a cylindrical liquid ring layer (liquid ring area). Under the action of centrifugal force, the solid particles with larger specific gravity settle to the A mud layer (solid ring layer) is formed on the inner wall of the drum, and then the relative speed difference between the spiral and the drum is used to push the solid phase to the cone end of the drum. After pushing out the liquid surface (shore area or drying area), the mud can be dehydrated and dried. It is discharged to the slag discharge port, and the supernatant is discharged from the big end of the drum to achieve solid-liquid separation.

How to deal with drilling waste at the well site with natural radiation?

KOSUN is a professional manufacturer in drilling waste management. KOSUN has many years of drilling waste management experience. It can provide supporting and efficient oilfield drilling waste mud treatment equipment for different types of waste drilling fluids, especially for waste oil-based mud and waste water-based mud. With rich experience in treatment, we can also provide professional drilling solid waste treatment equipment.

There are two main aspects of the impact of radioactive materials on people: one is that the radioactive material emits rays, it will not directly contact the body, as long as the distance is sufficient, it will generally not cause harm to the body. On the other hand, radioactive pollutants are in direct contact with the body, which is a great harm. We must be very careful to avoid contact with these pollutants as much as possible, so as not to cause unnecessary harm, but also as much as possible to avoid pollution and harm to the environment.

Natural radioactive materials can be treated by appropriate methods, by injecting waste into blocked or abandoned wells, and ensure that the water level is below the groundwater level; or discharge into the ocean after meeting the requirements of relevant environmental protection laws and regulations; or transform it within the allowable content of the environment, and stored in a specially designated place for storing natural radioactive waste; it can even be discharged into an isolated and non-evaporable pool. In order to better solve the problem of radioactive waste disposal and reduce disposal costs. Where radioactive sources are found, the equipment and tools used will also be contaminated by radioactive waste. Therefore, they must be properly handled to prevent secondary pollution.

Drilling mud solid control and waste management

Introduction of Drilling mud solid control system:

Solid control system is a technique used in a drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally, a solid 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.The mud system with 4 phases of solids control process can be understood as the 5 phase purification system. From shale shaker, vacuum degasser, to Desander cone, Desilter cone, and the decanting centrifuge: different working principle, different separation point. Every well drilling requires such a system to process drilling mud. However, per different well depth and different drilling conditions we’ll get different configurations and different results.

Introduction of Drillingmud waste management:

Drilling waste management system, also called as drill cutting treatment system or drilling cutting management system. According to different applications, it can be classified as water-base drilling waste management system and oil-base drilling waste management system.

The main Drilling waste management equipments are drying shaker, cutting dryer, decanter centrifuge, screw conveyor, screw pump and tanks. The drilling waste management system can effectively control the moisture content (6%-15%) and oil content (2%-8%) in drilling cuttings and stabilizes the liquid phase performance.

Solids Control and Waste Management

KOSUN focus on production Solids Control and Waste Management Equipment  in Drilling Operations since 1992. KOSUN is a professional company providing comprehensive solutions to solid waste treatment in the field of energy conservation and environmental protection, which focuses on development and services of complete technologies and equipment of sludge reduction and resource utilization.

The solids control system forms the first waste management practice in any drilling operation. It removes drill cuttings from the drilling mud at the surface just before the mud re-enters the mud-pit for recirculation. Apart from drill cuttings, the solids control equipment also removes some gases and other contaminants in the mud before they are re-circulated. The early removal of these solids avoids accumulation and clogging of the system and the separation devices sizes of solids.

The components of the solids control system will depend upon the types of drilling fluid used, these formations being drilled, the available equipment on the rig, and the specific requirements of the disposal option. But basically, standard solid control equipment will comprise of shale shakers, degassers, desanders and desilters. The mud passes over a shale shaker, which is basically a vibrating screen. This removes the larger particles, while allowing the residue to pass into settling tanks. The finer particles are further removed in the desanders and desilters. If the mud contains gas from the formation it will be passed through a degasser which separates the gas from liquid mud, having passed through all the mud processing equipment the mud is returned to the mud tanks for recycling, while the residue (drill cuttings with adhered drilling fluid) is either kept in a temporary storage facility for treatment and final disposal or direct discharged into the sea. In general, the solids control equipment reduces the volume of drilling waste requiring disposal.
