GN Solids Control provides a large number of solid control system and waste treatment system products to customers worldwide every year. GN Solids Control shale shaker, as the main equipment for drilling fluid treatment, as a vital role in the separation and purification of coarse solid phase in drilling fluid. Some weeks ago, GN Solids Control successfully delivered several sets of drilling fluid shale shaker screens, Desander and desilter for a domestic drilling company.

1. GN Solids Control desander

GN Solids Control sand remover is mainly used to remove drilling cuttings larger than 55 microns in drilling fluid. The drilling fluid purification sand remover is mainly composed of underflow screen and 10 inch sand removing cyclone. Under normal circumstances, the centrifugal pump is used to feed the desander. The cyclone uses a centrifugal pump to pump the mud into the swirl cone at high speed, and centrifugally separates the mud under the action of centrifugal force. After centrifugal separation, the lighter mud flows out of the cyclone outlet. The mud with high solid phase is ejected through the drip nozzle, and further sieved and separated through the underflow screen.

2. GN Solids Control Desilter

The structural principles of GN Solids Control Desilter and Desander are similar. The only difference is that the cyclone used in the desilter is a 4-inch cyclone. Generally, the number of desilting cyclones is an even number. Desilter is mainly used to remove solid cuttings larger than 25 microns in drilling fluid.

In addition to sand remover and desilter, GN Solids Control is also providing customers with integrated sand and desilter machine. This equipment integrates three devices: sand remover, desilter and underflow screen. Not only the two-stage separation of sand and mud removal is realized at the same time, but also the occupied area of ​​the tank surface is minimized. While improving the processing effect, it minimizes the floor space.

The separated liquid after desander and desilter can into fine solids separate process by decanter centrifuge

GN Solids Control, as a leading manufacturer in the solid control industry, has provided several customized systems including sludge treatment systems for customers worldwide. Recently, GN Solids Control has delivered a Chinese sludge treatment system with a processing capacity of 15m3 / h to a Chinese customer.

GN Solids Control sludge treatment system is mainly composed of the following units:

1.GN Solids Control feed pump

Since the sludge to be treated usually has a larger density and a higher viscosity, a powerful conveying system is used to pump the sludge. The solution adopted by GN Solids Control is a vacuum delivery pump, which mainly transports sludge with a solid content of 80% and particles smaller than 75mm. Any movable sludge or medium can be transported by GN Solids Control vacuum pump.

2.GN Solids Control premixed heating tank

When the sludge needs to be diluted with chemical substances, it is usually necessary to heat the materials to improve the homogeneous mixing effect. Mud mixers are also used to thoroughly mix oil sludge. At present, the available heating methods are resistance wire heating and steam heating.

3. Shale Shaker coarse screen processing device

The submersible pump pumps the diluted sludge into the GN Solids Control shale shaker processing device. The double-layer shaker is a common shaker. The shaker is equipped with an anti-splash device and a flushing nozzle to clean the screen surface at a certain frequency to prevent the shaker screen from clogging.

4.GN Solids Control two-phase separation centrifugal processing device

Most of the solid particles in the mud discharged from the vibrating screen are further separated by the GN Solids Control two-phase sedimentation centrifuge. After being processed by a centrifuge, the solid oil content is about 1% -3%. Thermal cracking equipment can be used for further processing of solids discharged from vibrating screens and sedimentation centrifuges

5.GN Solids Control three-phase dish centrifuge processing device

GN Solids Control three-phase disc centrifuge as a key processing equipment can obtain a large amount of clean oil (BS & W less than 3%) and clean water (oil content of 1000-3000ppm).

The GN Solids Control sludge treatment system is a compact and integrated system. The above treatment equipment can be placed in standard containers for easy movement and construction.
