GN Decanter Centrifuge and Cuttings Dryer for Africa Drilling Company

One set of GN decanter centrifuge and vertical cuttings dryer are using for Africa drilling company. The equipments list including:
2 units of decanter centrifuge，model GNLW363D-VFD
1 unit of vertical cuttings dryer，model GNCD930G
Matched with screw conveyor, centrifuge feeding pump and vertical cuttings dryer flushing pump.


The screw conveyor GN produced including 10 inch, 12 inch, 14 inch, 16 inch and 18 inch diameter for option, each section standard length is 12 ft, we can use different quantity sections as per client’s requirement of transfer length, such as 12 ft, 24 ft, 36 ft, 48 ft, 2 sections are connected by pin shaft hanger. The screw conveyor can be fixed speed or variable speed( manually speed adjustable) to control the feeding rate. The screw propeller material is High Chrome Alloy Steel for longer working life.


According to the installation position and function of the screw conveyor, there are auger system for primary shale shaker discharge solids collection, desander desilter discharged solids collection, feeding to vertical cuttings dryer feed hopper, solids discharge auger for vertical cuttings dryer, solids discharge auger for decanter centrifuge, etc. The protection cover on the U type reinforcing beam could be closed steel plate or steel grating for option.
Additional safety protection of the screw conveyor:
1) Pull chord emergency stop with wire rope to be provided along the length of Augur for Emergency stop；
2) Audio / visual alarm system on the auger control panel which will be automatically activated once the power is switched on followed by the actual auger startup with a safety delay time. Audio / visual alarm system to be in the OFF mode after some time once the auger starts operation.


If you need decanter centrifuge, vertical cuttings dryer, feeding pump, screw conveyor, pls contact with GN solids control.

GN Drilling Cuttings Treatment Equipment for Middle East Customer

One batch of GN drilling cuttings treatment equipments are ready for delivery to Middle East customer, including 3 sets of high G drying shaker GNZS594K and 2 sets of vertical cuttings dryer GNCD930G.
What is the difference of high G drying shaker with vertical cuttings dryer?
1. Application difference: The high G drying shaker is normally used to treat water based drilling cuttings, the vertical cuttings dryer is normally used to treat oil based mud/ drilling cuttings.


2. Working principal difference: High G drying shaker ( also called as high G dryer) is high vibration G force shale shaker with fine mesh shaker screens. It is drived by 2ea vibration motors, the shaker screen is 4 pcs of 585x1165mm composite material frame shaker screens. When the water based drilling cuttings are feed to high G dryer buffer tank, the massive G force immediately pins solids against the fine screen mesh ( as fine as 200 mesh/74 microns).Liquid passes through the screen and is recovered, while dry solids are conveyed and out by augers.


Vertical cuttings dryer ( also called as verti-G dryer), when the OBM or SOBM wet cuttings are feed to verti G dryer feeding port by screw conveyor, A stainless steel screen basket traps wet solids and accelerates it up to 900rpm with up to 420G, the liquid is forced through screen openings, the dry solids are extracted by the angled flights attached to the rotor, which rotate slightly slower than the screen. The tungsten carbide protect the flights from abrasive solids and ensures longer operation life.
3. Treatment result is different.
The high G drying shaker can dry the WBM drilling cuttings with moisture less than 30% ~ 40%, the vertical cuttiings dryer can dry the SOBM drilling cuttings with OOC <5%, which can be sent to Thermal Desorption Unit for further treatment.

16 Sets Drilling Mud Centrifuge and Vertical Cuttings Dryer for overseas oilfield service company

Recently 16 sets of drilling mud centrifuge and vertical cuttings dryer are ready for delivery to overseas oilfield service company.
One set of drilling mud centrifuge package including 1 unit of decanter centrifuge, telescopic skid and 1ea decanter centrifuge feeding pump. GNLW363D decanter centrifuge is the most popular high speed decanter centrifuge used for drilling mud treatment and drilling cuttings treatment. The bowl diameter is 14 inch, the bowl length is 50 inch, the designed treating capacity is 200gpm, and typical capacity is 132 gpm. The max bowl speed is 3900rpm, and typical bowl speed is 3200rpm. The max G force is 3063G, typical G force is 2062G. The separation cut point is 2 ~5 microns.

One set of vertical cuttings dryer package including 1 unit of vertical cuttings dryer, cuttings dryer skid, flushing pump and solids discharge system. The most popular vertical cuttings dryer model is GNCD930G, the treating capacity is 30 ~50 tons per hour. For the oil based drilling cuttings fresh collected from primary solids control shale shaker, the treated oil content in the cuttings is less than 5%. If the client needs less oil content in the cuttings, the solids discharged can be sent to Thermal Desorption Unit. The screen diameter is 930mm, we have 0.25mm, 0.35mm, 0.5mm three type screen opening for option. The rotation speed is 900rpm, G force is 420G, oil tank capacity is 48L. The main motor is 55KW, the oil pump motor 0.55KW.The standard vertical cuttings dryer with solids discharge collection hopper, as client’s requirement, GN designed customized solids discharge system with vibration motor for faster solids discharge.


Except for decanter centrifuge package and vertical cuttings dryer package, GN solids control also produce different size screw conveyor, high G drying shaker and complete line of solids control equipments and shaker screens.

Two Sets GN Container-type Cuttings Dryer Systems for Overseas Client

2 sets of containerized vertical cuttings dryer system are ready for shipment to overseas client. The technical configuration is as below:
1. Vertical cuttings dryer GNCD930G-GP, The rotor flights is hard facing to HRC65 for longer working life, the flights and rotor assembly is individually balanced, which is convenient for future replacement, individual oil lubrication system with automatic alarm for pressure limit.


2. Intermediate fluids collection box 1.5x2x1.2m, the fluids can be transferred to decanter centrifuge for further separation of the fine solids, the final treated fluids can be reused for drilling rig or used to prepare for new drilling fluids. The fluids can be also sent to final disposal treatment by adding chemicals to get pure water and dry solids for final disposal.


3. Screw pump as flushing pump of vertical cuttings dryer, Netzsch brand pump with Germany Brand Nord gearbox, fluids touch parts are made of Wear-resisting alloy material.


4. All of the equipments are installed inside standard container with customized decoration, such as insulation design for working in cold environment, doors and windows, open holes for screw conveyor, lightings, etc. The benefits for the customized containerized cuttings dryer system including: convenient transportation, keep the system warm in winter cold temperature, convenient operation and maintenance.


5. Screw conveyor to collect the discharged solids from the vertical cuttings dryer and transfer the cuttings box automatically, with proper auger support. GN screw conveyor with standard length for each section 12 ft, the client can select proposal sections for different transfer length as 12 ft, 24 ft, 36 ft, 48 ft. GN solids control can produce different size screw conveyor including 10 inch, 12 inch, 14 inch, 16 inch, 18 inch diameter screw conveyor with different flow rate and drived motor.
