GN Solids Control makes various size of decanter centrifuge and screw conveyors for drilling mud treatment and drilling waste cutting transfer. GN Solids Control finished some decanter centrifuges, vertical cuttings dryer, and some screw conveyors for an international drilling company.

Decanter centrifuge is the most popular separation equipment for liquid and solids separation. High speed and low speed decanter centrifuge can be used to treat drilling mud and drilling cuttings. Decanter centrifuge can be used for slurry treatment and waste water treatment. Decanter centrifuge can also be used together with chemical dosing unit for dewatering treatment.

Drilling fluid decanter centrifuge is an important solid control equipment for drilling mud separation system. It can separate solids greater than 2 microns, which can effectively solve the problem that other drilling mud separation equipment can not separate, and remove the ultra-fine harmful solid phase after shale shaker, desander and desilter mud cleaner separation.

If define from bowl size, GN Solids Control makes various sizes of decanter centrifuge, from mini size 9 inch, to middle size 14 inch, 18 inch, and big bowl size 22 inch and 30 inch. GN Solids Control makes fixed speed decanter centrifuge, VFD control centrifuge and FHD centrifuge.

Screw conveyor is a transfer machinery which uses motor to drive screw rotation and push materials to achieve the purpose of conveying. Screw conveyor can be located at job site horizontally, inclined or vertically, it has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, convenient closed transportation and so on.

Screw conveyor can be divided into two types: axial screw conveyor and shaftless screw conveyor. In appearance, it can be divided into U-shaped screw conveyor and tubular screw conveyor. Screw conveyor is widely used at drilling rig job site, especially the U-shaped screw conveyor is widely used to transfer drilling cuttings and other drilling waste materials.

GN Solids Control major products is to make full package drilling cuttings and drilling waste management equipment. GN Solids Control is capacity to make drilling mud solids control and drilling cuttings treatment equipment to fit for clients’ job site situation.

Before the end of the last month 2021, GN Solids Control shipped a cuttings dryer package for an Africa client. The cuttings dryer package will be used to treat the drilling cuttings generated from drilling mud solids control system. Below are the major processing equipment included in the cuttings dryer package.

1) There is Qty 1 vertical cuttings dryer in the cutting drying package. Vertical cuttings dryer is used before decanter centrifuge. It is used to reduce the OOC in the OBM cuttings and to recover usable drilling fluids. Normally, GN Solids Control use 4kw screw pump as flush pump for vertical cuttings dryer. Sometimes, clients use 7.5kw screw pump as flush pump in order to interchangeable with centrifuge feeding pump. GN Solids Control can offer flush pump electrical control inside the vertical cuttings dryer control panel.

2) There are Qty 4 fixed speed decanter centrifuge with high speed and lower speed for drilling mud treatment. It is the most hot sale centrifuge model from GN Solids Control: GNLW363CG. 5.5kw and 7.5kw screw pump is recommended to feed for the centrifuge. The electrical control of the feeding pump is inside the centrifuge control panel. As there must be interlock system between centrifuge and feeding pump to protect the centrifuge from overload.

3) Screw conveyor is a popular transfer equipment used at oil and gas drilling job site. It is widely used to collect drilling cuttings from solids control shaler shaker and mud cleaner. And than feed to other cuttings drying equipment. GN Solids Control makes various size screw conveyor, the auger diameter is 10 inch, 12 inch, 14 inch, and 18 inch. GN Solids Control offers fixed speed screw conveyor and variable speed screw conveyor for optional.

Through some months tough manufacturing, GN Solids Control finished a 56,000 bbl liquid mud plant. It is the largest liquid mud plant designed and made by GN Solids Control. The 56,000 liquid mud plant will be shipped to an international drilling fluids service company.

The liquid mud plant includes mud treatment modular, mud mixing modular and mud storage modular. The 56,000 liquid mud plant includes below modular:

1. Drilling mud treatment modular with horizontal mud tank: it includes 1 qty of drilling mud shale shaker, the model is GNZS594F. It is a 4-panel linear motion shale shaker to treat the drilling mud. 1 qty of middle speed decanter centrifuge, the model is GNLW452D. The middle speed decanter centrifuge is used to recover batonite. Besides the middle speed centrifuge, there is a high speed centrifuge GNLW363C. The high speed decanter centrifuge is used to recover fine solids and reduce mud weight. Operators can choose to use neither one of the centrifuge, or use both centrifuge.

2.Mud mixing modular with horizontal mud tanks: mud mixing pump 4 ea, mud mixing hopper 4 ea. The mixing pump type used in the liquid mud plant is centrifugal pump with dual sealing system. Besides mud mixing, centrifugal pump can also be used for mud feeding, for mud pump supercharge, for mud transfer and etc…

3.Vertical tanks for mud mixing: There are qty 70 vertical mud tanks with volume 500bbls (80m³). It is a hugh work to build such big qty big tanks.

Besides liquid mud plant, GN big advantage is to make drilling mud treatment system for oil and gas drilling, slurry treatment system and desandling plant for non-oil drilling mud, like water well drilling, piling, trenchless, CBM, micro tunneling, etc…). And GN major products is to make oil sludge treatment system, waste water treatment system, and other liquid and solids separation applications.
