Poor boy degasser is also called liquid-mud separator, it Is a pressure vessel in a fixed vertical position, inside is a defensive pipe against sprinkler. When contaminated mud is routed into the separator, it flows to the sprinkler, then spread to the defensive guard pipe, during this process, the head of entrained gases “break out”. The released gas then carried by the vent lines to remote location where it can be safely flared. The flow of liquid from the vessel can be regulated by a liquid-level-control valve or a U-tube, ensuring adequate retention time in the separator for the gas to break out.

Mud tank cleaning

After using the mud tank for a long time, there will be precipitation of solids and silts, even though we have a lot of solutions to less the precipitation, e.g. each tank should design several cleaning gate which is closed to the bottom, after several months, you can clean the tank bottom through the cleaning gate. Also we can design the tank bottom to round type, not level, it is easy to clean the tank. Most of the tank is designed with water line, which can be used to clean the tank top and tank bottom.

Even though there are a lot of ways to less the solids, you still need special equipments for the mud tank cleaning

. Firstly used a submersible slurry pump or centrifugal pump to transfer the slurry to the cleaning system, which is composed of shale shaker, desander, desilter, sometimes also with decanter centrifuge. The waste water can be re-used to clean the tank, the waste solids can be disposal or to the dewatering system for future process.

Hydrocyclones Silt Separation

Hydrocyclones are applicable in silt separation for dredging slurry separation. There are various size hydrocyclones, 2inch, 4inch, 8 inch, 10 inch, 12 inch, in oilfield drilling solids control system, the most common size is 4 inch, 10 inch and 12 inch. In the other application such as mining slurry separation, dredging slurry separation, in which include more silt, 2 inch, 4 inch , 6 inch is more popular.

You can get complete solution for silt separation from GN, we will put different qty and size hydrocyclones together so they will have many different assemblys with different cutting point separation and treating capacity, and match different model feeding pump. Now we have 500gpm, 1000gpm, 1500gpm 3 options mud cleaner, desander, desilter.

Desander Cyclone

Before GN provide 3 size desander cyclones, 8 inch, 10 inch and 12 inch. The 8inch cyclone is cast iron with Polyurethane material. The 10 inch and 12 inch desander cone is 100% PU material. Now our standard cone size is 10 inch with PU material, and the installation dimension is replaceable with Derrick 10 inch cone. The cut point separation is 45~75 microns, which is usually used after shale shaker and before desilter cone.

We have 3 options for the desander cyclones, 1ea cone can treat 500gpm, 2ea cone can treat 1000gpm, 3ea cone can treat 1500gpm. You can put the desander cyclones on desander equipment( without underflow shaker), or on GNZS752 shale shaker( mini shaker) or GNZS703 shaker to be act as mud cleaner.

Drillers Mud System

GN solids control offers a variety of drillers mud system, mud mixing/ recycling systems, spare parts and tooling designed to fit your need in Horizontal Directional Drilling or Oilfield applications. We can be your supplier for all of your drilling needs, including HDD, oil drilling, geothermal, CBM, water well drilling, diamond core drilling for mining , ground construction, TBM, dredging slurry separation system, piling slurry separation, drilling waste management equipments.

Flare Ignitor System

Mostly due to the need of harmful combustion gases, Flare Ignitor System must be placed far away from the residence and downwind areas; need for regular inspection gas tank gas margin, while ensuring that all lines intact.

In transport, lifting process to prevent damage to the ignition wire insulation. Install the igniter must be sure to select the open place.

Flare Ignitor System must be fixed firmly,with supporting guy wire. Movable control box must be placed in the environment , excellent place to protect the electronics components from moisture dust damage.

In the drilling project and supporting the use of mud-gas separator, refer to instruction manual mud gas separator relevant sections.

Mud plant agitator

For a liquid mud plant, the most important 3 equipments including: mud agitator, centrifugal pump & mixing hopper. GN mud agitator has been installed on a lot of mud plants. The connection method of GN gear box and electric motor is directly connected, based on power, we have GNJBQ5.5( 5.5KW) , GNJBQ7.5(7.5KW), GNJBQ11(11KW),GNJBQ15(15KW), GNJBQ22(22KW).

Usually the agitator shaft is fixed design(not customized), and the impeller can be customized if you have special requirement. The impeller size and power you required for a mud agitator is based on the mud density and viscosity, we can calculate according to the data you provided.

Vermeer HDD machine

Vermeer designs and manufactures horizontal directional drills, pneumatic piercing tools and vacuum systems. It is one of the best HDD machines manufacturer in the world, which is located in USA, Germany, Singapore, Beijing, Brazil, Netherlands, and have agents in most of countries.

When the HDD rig Is operated, sometimes you may need a mud cleaning system, which can process the used drilling mud and less the damage to the environment, sometimes it is required by the drilling, it should lubricate the drill bit. GN solids control can produce not only mud mixing system but also mud cleaning system for Vermeer HDD machines, and we have standard mud system in stock from treating capacity from 150gpm to 1000gpm. Welcome to contact GN solids control.

Cuttings auger conveyor

The cuttings auger conveyor can collect and transfer the cuttings not only from onshore drilling solids control equipments( from shale shaker, mud cleaner, decanter centrifuge), it can also collect the cuttings/used mud from offshore rig platform.

GN produced cutting auger conveyor is drived by electric motor and control control, which is installed at one end of the auger. The auger diameter and length can be choosed by the customer, which can decide the transferring flow rate, it depends on how many tons per hour cuttings your solids control system produced. Not only cuttings auger conveyor, GN solids control also manufactured vertical cutting dryer and decanter centrifuge.

Top 3 directional drills manufacturer in the world

America Auger , Vermeer and Ditch Witch are top 3 directional drills manufacturer in the world, especially for the HDD application, water well, construction and other engineering.

All of the above HDD rig manufacturer has a lot of dealers all around the world, in some countries, there is still no exact regulation for HDD mud treatment; but in some HDD applications, mud recycling is necessary, plus more and more countries issued much more strict regulations on environment protection, used drilling fluids for HDD can not be disposal directly, you will need a HDD mud cleaning/recycling system. GN solids control is a specialized manufacturer for HDD mud cleaning/recycling system.
