GN CBM Drilling Mud System

The desander should take suction from the degasser overflow tank and overflow to the adjacent downstream tank. Desilter suction should be from the desander overflow and again, overflow to the adjacent downstream tank.

Low level equalizers between the overflow and suction tanks ensure a backflow of mud as described above.Where the bottom of the cones lies several feet above the mud level in the tanks, the overflow line may create a vacuum which sucks solids through the overflows, thereby reducing separation efficiency. This can be overcome by installation of a vacuum break.Both desander and desilter shall installed on the mud tank.

GN Mud Cleaner is a desander and desilter mounted over fine mesh shale shaker
The Mud Cleaner is For use in weighted and / or expensive fluid systems
Discards drilled solids while retaining expensive barite, chemicals and liquids in the

fluid system,The advantage of GN Mud Cleaner is that we use PU material cones which gives you very longer life and our desilter cones is completed with Stainless Steel ball valve for control which helps customer easier for maintainence.

OOC is the most important parameter of verti G dryer. OOC, means oil on the cutting. In many countries, OOC should be reduced to a very low level, like 5%, 3% then discharge.

GNCD930 is a hot sold dryer model from world top solids control manufacturer – GN Solids Control. After treated by GNCD930 verti G dryer, OOC can reduced to 5%. Similar to Brandt and CSI.

Formerly, drilling cutting treated by vertical cutting dryer can centrifuge disharge to environment directly or bury deeply undergroud. But it is extremaly bad to the environment. There are many kinds of chemicals and heavy metal ion in the cuttings, They will sink into groudwater and pollute groudwater. The polluted water as water source is very bad to human beings.

Vertical cutting dryer and high speed centrifuge can reduce OOC less than 5%,But in many countries, the treated cutting still cannot discharge into enviroment. Other biologic treantment should be followed.still cannot discharge dischage directly. They just act as parts of waste management.

A vacuum manifold is attaching to shaker screen of vacuum shaker screen recovery system. Or it installs a vacuum manifolds which have a shaler screen attached to it.

The vacuum system attached to the shaker’s  basket, so the manifolds vibrates with the shaker while shaker running.

There is a vacuum line with a fluid/air separato attached to vacuum manifolds. The vacuum manifolds is connected to collection tank. The vacuum unit is installed as close as possible to the shaker to keep the distance that the recovered fluid is transported as short as possible.
