By using an efficient solution of the drilling cuttings waste management system and treat the solids well, the particles could be dryer and even reach the standards to be discharged, meanwhile, the expensive drilling fluids could be collected and put back to the drilling system.

GN DRILLING CUTTINGS WASTE MANAGEMENT EQUIPMENT

Ever since year 2013 when GN Solids Control firstly designed and put into reality the GNCD930 series cuttings dryer, GN has designed 2 kinds of drilling cuttings treating system, both combined by following equipment:
1. GNCD930 vertical cuttings dryer. It is like a drying step of a washing machine, by high speed vertical drying, the liquid phase, drilling fluid passes the mesh of the cone sized basket, while the solids phase, the cuttings, fall down to the discharge port. After treatment of GNCD930, the OCC could be less than 5%. And according to different cuttings condition, GN gives 3 optional mesh opening sizes. Clients could prepare all of the three for different conditions.
GNCD930 Vertical cuttings dryers are firstly designed for the OBM and SBM, but per some clients’ feedback, it could be useful for some water based mud, too.

2. After the GNCD930 vertical cuttings dryer, the drilling cuttings are collected while the drilling fluid falls into a container and to be pumped to next step, the GNLW363 series decanter centrifuges. GNLW363 series decanter centrifuges are the super star among GN centrifuge models. In every 10 sets of GN Centrifuges, 7 are GNLW363 decanter centrifuges. It has the medium size and more optional control panels for option. In solids control system, clients always choose fixed speed GNLW363, while in drilling cuttings waste management or drilling fluid treatment project, the VFD model with PLC control panels are more popular. In some none explosive conditions, clients could choose the more economic model, while in some countries and regions when IECEX or ATEX is a must, GN also have those models for option.

3. GNSC series screw conveyors. By providing screw conveyors of different diameters and length, GN has 12 models for option. Clients could choose per the transporting capacity and distance to be transported.

In old China, in the agriculture world, the autumn is the best season of year, because it is the season for harvest and rewards of one year’s hard work. Now, in this autumn, GN Solids Control is being rewarded for its hard work, too. Although the big situation is not so good, GN Solids Control is working well, always have orders waiting.
Just early this month, at beginning of 2017 autumn, GN just delivered solids control equipment for complete 3 sets of drilling rigs for Russia, including:

GN solids control for Russia

GN provides 3 sets solids control equipment for Russia

  1. Shale shakers of 9 sets: GNZS594E Shale shaker, linear motional shaker screens with 4 pieces composite material shaker screens. The screen area could reach 2.73 square meters
    1. Mud cleaners of GNZJ594E-3S16N, with 3 of 10 inch desander cones and 16 of 4 inch desilter cones. For each solids control system, there are one set of mud cleaner.
  2. GNZJ594E series mud cleaners share same shaker with GNZS594E shale shakers, with interchangeable spare parts for shaker parts and shaker screens.
  3.  GNLW decanter centrifuges of 6 sets. Decanter centrifuges are GN core products, and GNLW series decanter centrifuges’ sizes range from 9 inch to up to 30 inch. Big bowl middle speed decanter centrifuge GNLW452 are widely used for barite recovery of solids control systems and high speed centrifuges are used for waste management systems for the extra fine particles remove.
  4. Centrifugal pumps, GNSB series centrifugal pumps are used for feeding the desander and desilter cones, and also for the mixing hoppers’ feeding.

Besides above mentioned equipment, GN also provide the mixing hoppers, mud agitators, mud guns and other equipment, mud tanks for solids control equipment, and also for drilling waste management system for both drilling cuttings and drilling fluid.

Mud Agitator is one of the solids control equipments that are mainly used for you to mixing the drilling body fluids in the mud tanks to hold the solids inside the drilling fluids suspending other than sedimentation down to the tank bottom level.
GN’s sales team ever gotten many inquiries on the mud agitators; unfortunately, most of the buyers have no idea on how to choose the right product suchs mud agitator, shale shker, mud cleaner, decanter centrifuge, etc. for their project and even seldom know how to use the equipment adequately to ensure a longer life time. GN’s sales are good at comprehension clients’ specific request simply by asking few simple concerns. With the answer from the buyers, GN always could provide the best proposal for clientele. Now let’s see precisely what these questions are and exactly information GN need to give you a proposal.
a. What is the on the inside dimension of the mud tank or pit. From this concern, GN will know the inside duration, width and depth in the mud tank, and then GN will know how long the agitator shaft should be suggested to get clients and how big impeller should be used. For the deeply mud tank or ditch, the stabilizer will be presented to hold the agitator length for stable performance.

c. What is the shape of the mud tank, cylinder or square? Then GN will know tips on how to design the mud agitator.
chemical. What is the electric specification, generally GN would like to know the work site electric voltage and occurrence. Different countries may have various frequency, the 50 Hertz motor cannot be used beneath 60 Hz, and protection is ever the first believe we should keep in mind.
d. Will be S. G. of the chemical? For very thick water, GN will propose greater horse power motor to drive the particular agitator.
For some clients who have get the mud agitators through GN and make the mud tank by themselves, GN often recommends them to make the mud tank with same way of measuring, thus they can get the agitator all same model, which will be much better for clients’ future maintenance. GN advise the RPM setting on the mud agitator between 40-96, too high will disturb the actual solids suspending, while lacking will lead to solids sedimentation.

We have one consumer from Africa; require products & services for Winter Desorption Unit (TUD). Your customer gives requirements as down below:
1) Leak proof skips and waste oil aquariums (i. e., offshore mobile tanks) for the collection of
NAF drilled cuttings and other NAF rig wastes at THE CLEINT’s drilling rigs.
2) Pier access for PSVs supplied by THE CLEINT.
3) Dockside services (i. e., employees, cranes, and forklifts) intended for loading / offloading skips/waste oil tanks from the PSVs and loading the skips and / or waste oil fish tanks on trucks.
4) Passenger trucks for hauling the skips and / or waste oil storage containers to and from the treatment center and within the treatment facility and with hauling treated residue in the treatment facility to the landfill.
5) Treatment facility for the thermal digesting of NAF drilled cuttings and other NAF rig toxins, including any containers essential for transporting the treated silt to the landfill. Treatment facility should certainly have sufficient space to support filled skips and shop empty skips until indexed by THE CLEINT. Treatment facility should certainly have capability to recover, retail store and transport base essential oil from treated cuttings for the dock
6) Hazardous waste materials landfill for treated deposit disposal.

As we are genuine solids control and drilling waste management equipment producer, we cannot offer the services. But we recommend specialist drilling waste management vendor to them. In this case, we can cohesiveness with the Service Company, and give very good equipment and service to the bottom user.
The main equipment stated in the project is heat desorption unit (TUD), GN can offer mobile thermal desorption unit (TUD), including Serving Hopper, burner, thermal desorption unit, cyclone dust parting, vapor recovery unit, essential oil water separator, water tank, cooling tower, water screen duster, condenser, process control etc .
Except for TDU, GN Solids Control also create all line of solids control equipment, eg. Shale shaker, decanter centrifuge, mud cleaner, agitator, centrifugal pump, 1000gpm mud cleaning system, 500gpm mud system etc .
