Last week, GN Solids Control finished a mud decanter centrifuge dewatering system for a TBM engineering company in China. The decanter centrifuge dewatering unit will be used to treat waste slurry from TBM drilling.

big bowl decanter centrifuge

The decanter centrifuge used in the dewatering system is a special model with very huge bowl: GNLW764A-VFD. The bowl size of the centrifuge is 760mm (30 inch) . The bowl length is up to 3328mm. It is a high speed 2-phase decanter centrifuge for liquid and solids separation. The cut point of the centrifuge is 2 ~ 5 microns. It is a dual motor centrifuge. The main drive motor used in the decanter centrifuge is 160Kw, and back drive motor is 90kw.

The chemical dosing unit used in the centrifuge dewatering unit is a very big size GNDW-6000L. The chemical dosing capacity of the unit is 6000L per hour in order to suit the big bowl centrifuge handling capacity.

The GNLW764A-VFD 30 inch big bowl decanter centrifuge is fixed inside a 40ft container, there are windows and door with access to discharge soil by screw conveyors.The GNDW-6000L chemical dosing unit is fixing on another 40ft container and lies on the top of the centrifuge container. It can minimum the footprint to save space.

Mud Cleaning system and drilling fluids decanter centrifuge for international drilling company

A customized drilling mud processing system is is ready for shipment at GN Solids Control Beijing factory. It mud cleaning system is composted of a mud cleaner, a mixing hopper, and a centrifugal pump for mud mixing and transfer.
The drilling mud cleaning and mixing system is designed and made by client’s request to suit his drilling mud situation. Normally, mud cleaner is equipped after a pre-seperation shale shaker. But in this mud cleaning system, the first separation equipment is mud cleaner.

Drilling Mud Cleaner

The reason why the client do not use shale shaker is that, they said the solids content in the mud is not much high. And mostly are fine solids. In this case, the drilling mud can be separated by mud cleaner directly. It is to save cost. As once the shale shaker is running, clients need to replace shaker screen periodically. It is a continue cost for operation. While delete the shale shaker, the system can meet client’s request. It can save the cost of shale shaker, and furthermore, the can reduce wearing spare parts shaker screen cost.

But if the solids content is high, or the particle side is big, which is over the hydracyclone separation point and its mud handing capacity, it is better to use a shale shaker before the mud cleaner. At one hand, the shale shaker can reduce the flow rate which feed to the mud cleaner. At another hand, after the shale shaker separation, the solids content will be reduced, and the big size particle are total removed based on the shaker screen API size and cut point. It can increase the hydraucyclone separation efficient, and also to avoid the fast wear out the hydraucyclones. 10 inch desander cone and 4 inch desilter cone are the most popular cyclone sizes used for drilling fluids separation system. Operator can choose the to use only desander cone or desilter cone, or both based on the mud condition and their budgetary. Desander and / or desilter cone quality depends on the handling capacity of the whole system.

Drilling Mud Centrifuge

Feeding pump for mud cleaner is centrifugal pump. The centrifugal feed pump is located on tank slope for compact design and for maximize the total tank usable volume.

After the mud recycling and mixing system, a drilling mud decanter centrifuge is used for fine solids separation. As there will be more and more fine and ultra fine solids after some circulation of the system. Decanter centrifuge will be used to reduce the mud weight.

GN Non Oil Drilling Mud Recycling System is Widely Used

The business of today’s GN has been divided mainly into 2 scopes, one is the normal drilling mud recycling, and the other is the waste management including the waste coming from petroleum related and other separation industries. This blog is mainly talking on the drilling mud recycling system that used in non oil drilling industry.
In oil drilling, the drilling depth and safety regulation request large drilling mud storage and more solids control equipment. Thus, the mud recycling system is always equipped with degasser unit and large volume mud tanks.

HDD Mud Recycling System

Comparing with the mud recycling for oil industry, the unit for non oil drilling is more compact and less equipment needed.

Trenchless/No Dig HDD project – The mud recycling system used in this type drilling is matching with a No dig rig. In some project for long distance pipeline and cables laying underground, it is inconvenient to dig an open groove on the ground as that will interrupt the normal traffic. The trenchless is an ideal choice. The mud recycling system for this project is always consisting of 3 stages separation as shale shaker unit, de-sanding and de-silting cyclone.
Piling is the main method to install the bridge supporting pillar. A de-sanding unit with a small tank would be enough to remove out the coarse solids from the drilling fluids. The de-sanding unit is a composition of de-sander cyclone and shaker unit that can separate out the solids with size of 40-70 microns. Piling does not request very clean mud; less equipment involved makes the recycling unit for piling is very compact.
GN also can manufacture the mud recycling system for tunneling project. For micron tunneling, GN has model available with capacity of 120m3/h, 240m3/h and 500m3/h. For large flow rate request, GN has the mud plant GNMS -3600M with treating capacity of 3600m3/H.

Tunneling Mud De-sanding Plant

Besides, GN’s mud recycling system can also be used in water well drilling, coal bed methane exploration, dredge slurry separation and the mining flushing waster cleaning process.

For the upcoming no dig show this September in Australia, GN solids control would like to show there one set self-contained 200 GPM drilling mud recycling system for HDD projects. As a leading manufacturer especially for drilling mud recycling equipment, besides the large footprint mud system for oil drilling, GN solids control could also provide compact structure design mud recycling system.
According to the HDD rig mud flow, GN’s economic mud systems are classified as 150/200GPM, 350GPM, 500GPM, 800GPM/1000GPM and 1500GPM. Just like the unit of 200GPM would be shown in Australia, though it is small footprint, it has all necessary functions for drilling mud recycling and mud re-configuration.

200 GPM HDD Mud System

Below is the equipment list for the 200GPM unit
1. GNZY753-4N shaker and de-silter composition unit which has the functions for first stage primary solids separation and second stage for drying the solid discharged from the 4” cyclones. This unit has a top located buffer box for well back drilling mud feeding, the bottom layer screen of this unit remove the coarse solids, liquid goes through the mesh screen opening and gets down to the storage tank. Pumped by a 15hp centrifugal pump, the liquid was transferred to the de-silter cone for fine solids removing. The upper layer screen with much finer opening would block and separate out the finer solid cuttings.
2. GNSLM20A-110 Jet mud mixer is used for adding the mud chemicals and re-configuration of the drilling mud. The beneath located mud tank was divided into 2 compartments and one of them is used for mixing and storing the active drilling mud. The mixing pump adopted is same with the one for feeding to de-silter cones. That would be much easier for future maintenance and parts replacement. The mixing pump could also be used as discharging pump for transferring the active mud to the rig.

GN also has the model of GNMS200-D and GNMS1000-D available and the treating capacity is separately 200GPM and 1000 GPM.
The advantage of this type mud recycling system is cost competitive. By connecting with storage tank and mud mixing hopper, this de-sanding unit could also be used in other kind of project like the small horizontal directional drilling, micro tunneling and water well drilling.

Economic Mud Recycling Unit Layout

GN recommends the layout of this economic mud recycling system:
1) Mud Pit
2) Submersible Slurry Pump
3) Mud Recycling System
4) Storage Tank
5) Outlet Pipe
6) Jet Mud Mixer.
GN Solids Control also offers submersible slurry pump, mud storage tank, as well as jet mud mixer per request.
