vertical cuttings dryer

As is known to all and recognized by more
and more people, a waste management system is more and more important for an
oil and gas drilling jobsite. In some countries, there are strict laws that
without a drilling waste management system,
the drilling rig is not allowed to start.

Nowadays, the most popular waste management
system is combined by a vertical cuttings dryer and a high speed decanter
centrifuge. The vertical cuttings dryer is working like a washing machine’s
drying process, and the liquid phase discharged by the vertical cuttings dryer
falls into a tank under the cuttings dryer, and then transferred to the
centrifuge for further treating.

GN Solids Control is very professional in
manufacturing such waste management systems. Just in year 2014, GN has produced
tens of similar systems with one of GNCD930C/CVFD vertical cuttings dryer
and a GNLW363CG/CG-VFD decanter centrifuge.
Such systems are working well at jobsites of many countries and places,
including Shell’s and Baker Huges’jobsites.

Although all such systems are for further
separating the drilling cuttings discharged by solids control system in former
phase and they are nearly same, but since each jobsite is different, the
feeding method differs a bit. Per the layout of jobsite and the material
conditions, there are mainly 3 kinds of feeding methods:

1.      Using
a hose pump for transporting the material into the vertical cuttings dryer. A
hose pump itself is small in size. It has some self suction function, but not
so common as following two methods.

2.      Using
a screw conveyor (auger) and a screw pump for feeding the
vertical cuttings dryer.

3.      Using
two screw conveyors for feeding, one is horizontal and the other is a slope
one.

In both above mentioned methods, the first
screw conveyor could have a hopper for collecting drilling cuttings.

No matter which method is chosen for a
certain jobsite, it depends on the jobsites’ space and requested layout, and
also affected by material condition as the density and viscosity. May you have
requests for this, welcome to contact us freely and our engineer will make out
for you the most suitable solution.

After a long holiday, which is the longestholiday in China, GN is back to work with full energy. Spring festival is mostimportant festival for every Chinese. After spring festival, according toChinese calendar, the new year starts. GN Solids Control is having a great start full of new orders.

Just before the holiday, GN has dispatched
20 sets of centrifuges to loading port, these centrifuges will arrive to
different countries in Middle East and Africa. In order to finish this order in
time, GN Producing department has been working around clock for at least 50
days.

Among all the equipments used for oil and gas solids control and waste
management
, Decanter Centrifuge could better show a manufacturer’s
capability for producing. Each year, GN produce around 150 sets centrifuges,
and 70% of those are exported.

What Centrifuges does GN produce?

1.      High speed Decanter Centrifuge GNLW363C
series decanter centrifuge
. This is 14 inch bowl decanter centrifuge,
and very popular size and design. For the same model, GN has highest
configuration and economic configuration available. The highest configuration
is suitable for waste management use and also regarded perfect as dewatering
centrifuge. The economic configuration is suitable for separating the fine
particles for solids control system. For each configuration, there are fixed
speed and VFD controlled available.

2.    Middle
Speed Decanter Centrifuge GNLW452, with a 18 inch diameter bowl. In some cases,
it is regarded as big bowl centrifuge. it is perfect in practice for recovery
the barite in solids control system. It has only one motor, and a middle speed
of 1800RPM.

3.      Big
Bowl Decanter Centrifuge GNLW553VFD Centrifuge, with 22 inch diameter bowl, and
71 inch long. It is a bigger sized GNLW363C decanter centrifuge.

4.      Baby
Centrifuge, GNLW223, the bowl diameter is only 9 inch, it is commonly used for
diamond drilling or some mining projects.

Among those above mentioned decanter
centrifuges, GNLW363CG-VFD is the best seller. And it is always used for
drilling waste management systems together with other equipments for further
treating the drilling cuttings from a solids control system. For WBM systems,
they always use high-G dryer shaker, and for OBM
and SBM, they always use vertical cuttings dryer. Both
mentioned extra equipments are available by GN Solids Control.
