Why choose GN solidification unit?

Applicable for both oil based drilling cuttings and
water based drilling cuttings

It produced a environmentally safe and dry material
which is acceptable for landfill or land farming disposal.

It produced a relatively dry material with steadily
structure which is cheaper for transport or disposal, it is an cost effective
way for drilling cuttings disposal if it is laws allowed in that country.

Except for stabilization unit, GN also provide
drilling cuttings treatment system for both water based mud and oil based mud, we
could provide the turnkey solution for drilling waste disposal.

As the most
professional drilling waste management system manufacture in China, we have
sold over 30 sets of standard complete drilling waste management systems to
Africa, Middle east, Russia, Australia, Indonesia and Europe market. Especially
for Africa market, we sold a lot of standard and customized drilling cuttings
treatment to drilling service companies. Part of our case study as below:

1 Our sales and after-sales service team just came
back from a drilling rig in Nigeria, they just finished the commission service
successfully for 3 sets of drilling waste management systems.

The equipments list include:

3 sets of vertical cuttings dryer

6 sets of VFD decanter centrifuges

9 progressive cavity pumps, 6 for feeding decanter
centrifuges, 3 for flushing the cuttings dryer.

15 screw conveyors for transfer drilling cuttings,
each dryer need one feeding screw conveyor, one solids discharge conveyor, each
centrifuge need one solids discharge conveyor.

(2) 2 Package Drilling waste management equipment to

The same client bought 2 sets of same drilling waste
management system, including 2 vertical cuttings dryer and 4 decanter
centrifuge with telescopic skid and feeding pumps, screw conveyors.

(3) Containerized drilling waste management system ,

1 sets of vertical cuttings dryer, 1 set of double
deck high G dryer, 1 set of decanter centrifuge all installed inside the
container with opened door and windows, stairs, handrail, walkways are

(4)  Several
units of decanter centrifuges shipping to Africa mud service companies,

They are shipped by 2 batches to reduce the delivery
time as the client’s request.

(5) Decanter centrifuge working for offshore rig in

Not only for land rigs, our drilling waste decanter
centrifuge can be also used for offshore cuttings treatment, and less the drilling
waste as much as possible.

…and more cases pls check with GN solids control
sales, or follow GN updated news.

As one of the
lead manufacturer of decanter centrifuge screw conveyor in China and with
branch office in Houston , GN solids control produce different models of
decanter centrifuge over 250 units every year.

The material of the whole screw conveyor is stainless
steel 316L, the flight of the screw conveyor is protected by the tungsten
carbide tiles over 4mm thickness, the material is YG8 with hardness factor
89HRC. The main bowl is made of duplex stainless steel 2205, which is better
than SS316 and SS304. The other bowl assy is made of SS316L. This is the basic
configuration of GN premium decanter centrifuge. The opening of the screw
conveyor can increase the treating capacity and make the performance better. The
tungsten carbide tiles are interchangeable when the old ones are damaged.

Even GN economic configuration decanter centrifuge,
the flight is protected by special ceramics tiles. The other parts are with
same material with premium decanter centrifuge.

The screw conveyor inside the centrifuge bowl is the
essential parts for a decanter centrifuge, the design and protection of the
screw conveyor will directly influence the centrifuge’s performance. The bowl
assy is the main and most important part of decanter centrifuge.

Expect of decanter centrifuge screw conveyor, GN
solids control also produce screw for the auger. Screw conveyor/auger is common equipment to convey powder, granular and
small lumpy materials. All bearing operate under dusty conditions. Therefore,
reasonable operation and maintenance is vitally important. The following
paragraphs describe main requirements of operation and maintenance.

The auger can be used to transfer the drilling
cuttings from the solids control system cuttings collection box to the vertical
cuttings dryer
, and as collection auger for the solids control system shale
shaker, desander, desilter, decanter centrifuge, and transfer the dry solids
discharged from vertical cuttings dryer.

Now we have 20 units of decanter centrifuge in stock,
welcome to contact with GN solids control.

Oil sludge
waste stabilization and solidification unit is a customized system to improve
pollutant retention and give the material obtained a certain structural
durability. Their objective is thus not to achieve a simple cladding of the
contaminated material in an inert matrix, but a complex physical-chemical
process to obtain stabilization and solidification of the pollutants.

Why use stabilization
and solidification unit for oil sludge waste?

Oil sludge
waste come from different ways, like drilling waste storage tank/ pit/ lagoon,
tank bottom cleaning, cuttings separated from drilling waste management system,
solids control system, etc. The oil sludge waste should be proper disposal to
prevent the destroy of environment. The trend of drilling is no-pit drilling in
the future along with the much more strict environmental laws in most of the
countries, which is combination of drilling mud solids control system plus
cuttings transferring system, drilling cuttings treatment system, cuttings
disposal system. GN customized designed cuttings solidification/ stabilization
unit and TDU( thermal desorption unit) are both cuttings disposal methods.

The main
components of GN stabilization/ solidification unit:

1 Absorber conveyor

2 Cement Conveyor

3 Solidsfication Mixer

4 oil
sludge waste collection hopper

5 cement
storage box

6 skid,
handrails, stairs

Working process of GN stabilization/
solidification unit:

sludge waste collection hopper collects all the drill cuttings & oil sludge
waste, transported to the mixing chamber by the screw conveyor.
2) Cement storage box is keeping cements powder, through the tubular screw
conveyor, powders are sent to the mixer at pre-set capacity.
3) In the same way, absorber is kept in a box, then sent to the mixer by tubular
screw conveyor.
4) The high-shear mixer mixes all the material, and push to the front at the
same time.

agents for the solidification/ stabilization unit , pls contact with GN solids
