The solidification unit and thermal desorption unit,
as one of the most efficient and economic drilling waste disposal method, has
been widely required by drilling waste management companies. GN new developed solidification
unit has been shipped to domestic client for no-pit drilling together with our
hi-G dryer system.

We have developed different customized drilling waste
management system for both water based drilling cuttings and oil based mud
& synthetic based mud.

For example:

(1)  
Vertical cuttings
dryer +decanter centrifuge with telescopic skid and small tank

(2)  
HI-G dryer
shaker+ decanter centrifuge for water based mud with mud tank

But the cuttings discharged from the vertical cuttings
dryer system, decanter centrifuge or hi-G dryer system is still a problem, they
are improper to be re-use, or disposal directly or difficult to be treated or
transported, because of the constituents of the cuttings are not proper for
land application or burial approaches. That is why GN will develop our own solidification
unit and thermal desorption unit to provide our clients a complete drilling
waste disposal solution for no-pit drilling.

The configuration of solidification unit as below:

1 ea cuttings hopper
with 5cbm capacity

1 ea cuttings
transfer screw conveyor with 7.5kw motor

1 ea SS304 steel
Absorber transfer screw conveyor with 1.1kw motor

1 ea SS304 steel
cement transfer screw conveyor with 1.1kw motor

1 ea SS304 Steel
solidification mixer with 2 reverse rotation screw impeller with 11kw motor

Various materials can be added to cuttings to solidify
and stabilize them, to get more details of GN solidification unit, pls contact
our sales.

As the most professional manufacturer of drilling
waste management system, GN solids control has provide a lot of drilling
cuttings treatment system for drilling companies, like CNPC, Sinopec,
especially in 2015, after Chinese government enact new laws for the drilling
waste disposal.

GNZS706E
double deck shale shaker has been widely used for mineral dressing/ ore
separation project, for example, gold recovery. We use different mesh screen to
separate different required ore size, normally the top screen is 3mm opening steel plate screen( or polyurethane material screen for
longer service life) to separate the big solids bigger than 3mm, it can protect
the bottom screen and make the working time longer. The bottom screen is customized,
because different minerals will need to separate different size ore.

GNZS706E double deck shale shaker specifications:

Total screen area 4.66m2( 52.5 ft2), top screen area 2.03m2(24.2ft2)
with 3 panels screen, bottom screen area 2.63 m2(28.3 ft2) with 3 panels screen,
up to 7.0G( adjustable), linear motion shale shaker. The Max treating capacity
is 140m3/h.

Mineral
engineering, mineral processing, or mineral dressing or ore dressing, is the
process of separating commercially valuable minerals from their ores. The simplest sizing process is
screening, or passing the particles to be sized through a screen or number of
screens.

GN solids control also provide a solution to put the hydrocyclones on top of the double deck
shale shaker, as a simple/ compact desanding unit. The working principal is
different with the double deck shale shaker. When worked as a double deck shale
shaker, the material is feeding to the buffer box and flow to the top screen to
separate course ore, and drop down to the bottom screen to separate the required
size.

When
working as a desanding unit with the hydrocyclones, which is used to separate
more fine solids. The material is feeding to the bottom screen to separate
course size then use a centrifugal pump for feeding to the desander cone, to
separate solids bigger than 75 microns, the top screen function for drying the
separated solids size and recycle more fluids.

GN decanter
centrifuge can be applied to both oil based mud and invert drilling fluids, and
water based drilling fluids and Synthetic Based mud.

INVERT
drilling fluids are generally used where drilling problems not easily handled
by water-based fluids are expected, or in situations where the invert drilling
fluid is more economical. The major advantage offered by invert fluids is
increased borehole stability.

GN solids control specialized
at customized TBM slurry separation plant with polymer mixing and dosing unit
as a complete system, the polymer mixing unit is applied for polymer flocculant
mixing and feeding to the dewatering centrifuge to get the water as clean as
possible, to separate more fine solids under 5 microns.

TBM
is the short name for Tunneling Boring Machine, Tunnels of less than a metre or
so in diameter are typically done using trenchless construction methods or
horizontal directional drilling rather than TBMs.

We
ever designed a containerized dewatering unit for Tunneling project with the
same application, the main purpose is to get clean water, and dry solids for
disposal. The polymer mixing unit can be installed inside the container
together with GN big bowl decanter centrifuge, by this way, it is convenient
for movement, also it can be located on the skid without standard shipping
container for cooling and easy maintenance, also the cost is much cheaper. We
can make it customized to meet the client’s requirement.

There
are 3 parts in the TBM slurry separation plant: Solids removal unit, polymer
mixing and dosing unit, dewatering unit with dewatering centrifuge. We provide
various options for solids removal unit/ mud cleaning unit, depends on your
required electricity power consumption and budget, we can provide 2-phase
cleaning compact design( double deck shale shaker + desander cone or double
deck shaker + desilter cone) or 3-phase cleaning premium mud cleaning system,
with shale shaker, mud cleaner( shaker, desander cone, desilter cone 3 in 1).

Our
dewatering unit can be applied for both powder polymer and solution polymer,
with pre-humidifyng
system for the powder and dosing system.

We can make the dewatering centrifuge on the
same skid with the dewatering unit or separately. If you are interested in more

As
the suddenly dropped down in 2014 and at the beginning of 2015, oilfield
related projects are all slow down, and people stop drilling, service and see
what happened then. Although it settles up to USD60 a barrel recently, many
companies are still in a position to wait and see. At such cost sensitive period,
the drilling contractors, service companies intend to rent or buy solids
control equipments with good quality and competitive price to reduce their
production cost and make profit. GN solids control is a new brand in US market,
but we are not new for solids control industry, our solids control &
drilling waste management system has been working in many fields to over 60
countries in the world, including US, Canada.

We
have separated brochure for vertical cuttings dryer , decanter centrifuge,
drilling waste management system, welcome to visit us at OTC or Houston office
and get more details.

Screw
conveyor is widely used for oil & gas drilling zero discharge drilling
waste management system, the purpose is to collect and move semi-solids
materials, so you can save a lot of labors and more efficient to deal with the
drilling cuttings which should be cleaned and handling before discharge.

Installation
of screw conveyor in the drilling waste management system:

Normally
it is installed horizontally and at a slight incline which is supported by a
customized steel frame according to the distance to the vertical cuttings
dryer, but the angle is normally less than 45 degree. Too incline angle will
influence the moving efficiency of the screw conveyor.

Structure
of Screw conveyor

It
consists of a trough or tube containing either a spiral blade coiled around a
shaft, driven at one end and held at the other, or a “shaftless
spiral”, driven at one end and free at the other. Variable frequency
electric motor can be used to provide a variable speed, which is for the
different drilling cuttings conditions and required moving rate.

The
solids discharge end could be customized design according to the rigsite’s
layout, side discharge or bottom discharge.

GN
solids control standard screw conveyor

There
is hopper opening screw conveyor which is usually used to collect the cuttings
from the shale shaker, desander, desilter, decanter centrifuge. And others are
closed cover screw conveyor, and outside the U-type trough, you can choose with
the frame support or without.

We have screw diameter of 12inch, 14inch,
16inch, 18 inch for option, and the screw conveyor length is divided to
different sections, each section is connected by the bearings, each section is
standard 12ft, you can choose 2 section( 24ft), 3 sections (36ft) or 4
sections(48ft).

Auger
is developed as a traditional drill cuttings transferring method, more and more
people choose cuttings pump or vacuum unit to replace it.

A
lot of waste water is produced together with sludge during the process of
mining exploration. More and more countries turn to or already enact more
strict laws for the drill cuttings/ mine water treatment, to oblige the
drilling contractors to be more cautious of the issue of waste treatment and waste
water drain off.

GN
designed dewatering unit/ solids removal unit/ mud cleaning system is suitable
for such applications. GNLW223 centrifuge is the essential equipment in the
system.

The
compact size( 9 inch bowl diameter, 26inch bowl length), high speed( up to
4500rpm) and separation cut points(up to 2 microns) and high G force ( up to
2500) make this model centrifuge become more and more popular in this industry.
Before submit our proposal, we need the client to do the lab test to figure out
the solids size distribution inside the material, and get the recommendation
for the flocculation proposal and result, then we will analyse the datas and
give the best solution to our clients to meet a wider variety of requirements.

The
separated solids should be taken as dry as it can, and be collected by the
truck and send to construction industry. The clean water is drain back to the river,
lake after waste water treatment center.

Not
only for mine waste water, this dewatering unit/ solids removal unit can be
also applicable with industry waste water treatment, construction waste water,
dredging slurry separation, oilfield waste water treatment, etc all the type of
solids-water separation works, it works together with flocculation and other
chemicals.

If
you are in the project of mine waste water treatment, mine sludge separation or
you are under the pressure of government laws about the drilling cuttings, pls
consult with GN solids control, for America clients pls contact with GN solids
America to get a proposal.

2)      Vacuum
transfer systems

3)      Positive
pressure transfer systems

We
will use different cuttings transferring equipments in different drilling waste
management system design, it depends on the space, installation, materials,
etc. The most common and economic way is screw conveyor to feeding for the
vertical cuttings dryer and collect the dry solids from the solids discharge
port of VCD and transfer to cuttings box.
