High G Drying Shaker and Decanter Centrifuge for Oman Project

Recently one batch of high G drying shaker and decanter centrifuge are ready for shipment to Oman, including screw conveyor transfer hopper, high G drying shaker module, decanter centrifuge module. The technical configuration is as below:


1. High G drying shaker module, GNZS594J high G drying shaker installed on the mud tank, with screw conveyor transfer system to transfer the drilling cuttings automatically. Four panel composite material frame shaker screens with 2 or 3 layers of stainless steel wire mesh are installed on the shale shaker, the shaker screen is produced comply with API RP13C standard.


2. Decanter centrifuge module, GNLW363D decanter centrifuge installed on the mud tank, with screw conveyor transfer system to transfer the discharged solids to cuttings collection box automatically. Also we can provide variable frequency drive decanter centrifuge with better treatment performance.
Firstly the drilling cuttings are feeding to high G drying shaker to separate coarse solids and reduce the solids content, the fluids will drop into the mud tank under the high G drying shaker, the screw pump will feed the fluids to high speed decanter centrifuge to separate fine solids from the drilling fluids, the clean fluids will be recycled and back to solids control system to prepare for new drilling fluids, the drilling cuttings are transferred by the screw conveyor.
This system is customized designed for water based mud drilling cuttings treatment project in Oman, with electric control system and electric motor compliant with ATEX standard. For OBM and SOBM drilling cuttings treatment project, GN standard GNCM-40A drilling waste management system will be recommend, which consists of GNCD930G vertical cuttings dryer, GNLW363D decanter centrifuge with feeding pump, screw conveyor, mud tank skid and accessories.

GN Desander and Desilter Centrifuge for China Drilling Company

Recently one unit of desander desilter centrifuge is ready for shipment to China drilling company.


GN Desander and Desilter Centrifuge is an efficient solids liquid separation equipment mainly used to remove solid particles such as sand and mud in drilling fluids. It is a specially designed big bowl decanter centrifuge, which separates solid particles from drilling fluid under centrifugal force through components such as a rotating bowl and a screw propeller, and discharged from solids discharge port and fluids distribution port. The Desander and Desilter Centrifuge has the advantages of wide separation particle size range, large treating capacity, compact structure, and simple operation. It can be used to replace the desander desilter mud cleaner more efficiently, with higher separation efficiency and better quality of recovered drilling fluids. The desander and desilter centrifuge has a wide range of application prospects in fields such as oil drilling, which can effectively improve the solids control quality and drilling efficiency of drilling fluids, and reduce the drilling costs.


GN decanter centrifuge applications including oil and gas drilling solids control system, drilling waste management system, oil sludge treatment plant, HDD mud recycling unit, Mining tailing slurry dewatering, TBM slurry separation, construction engineering mud treatment, mining slurry separation and other mud treatment. GN can provide CNEX, IEC EX, ATEX explosion proof motor and control panel for your option. The bowl and screw propeller rotate in the same direction with a certain differential speed, under the centrifugal force, solid phase is dropped on the bowl wall to form sediment layer, then push to the cone section and discharge through the solids discharge port.
Except for desanding desilting centrifuge, GN solids control also produce linear motion shale shaker, mud cleaner, vacuum degasser, 3 phase decanter centrifuge, vertical cuttings dryer, screw conveyor, centrifugal pump, mud agitator, mud tank system, etc solids control equipments. If you need a desanding desilting separation equipment, pls contact with GN solids sales.

GN Solids Control attended 2024 Beijing CIPPE Oil Equipment Show

This week GN solids control attend 2024 CIPPE oil show in Beijing. As one of the professional oil exhibition in China, we participate in CIPPE oil exhibition every year, to show our most advanced technology and equipments and meet with clients from domestic and worldwide.


This year we showed the equipments as below:
1. ViST vacuum screen technology to work with 4 panel shale shaker for drilling fluids recovery and reduce drilling waste, it can save money for operation on drilling fluids and drilling waste management. The ViST pan is installed under the last screen and connected to ViST vacuum unit. The air compressor or rig air supply should be provided to create suction on the last screen surface, it can reduce the liquid on the cuttings by 30% ~50%.


2. Sludge vacuum pump and vacuum cleaner, GNSP40B & GNSP10B, it is 100% air operated, no need electric power, suitable for hazardous area application, it can be used to transfer liquid, wet sludge and solids, it can transfer solids size Maximum 50mm or 75mm, sludge solids content up to 80%.


3. Vertical cuttings dryer GNCD930G-VFD
4. GNLW363D-VFD decanter centrifuge, it is the most popular model used for drilling fluids treatment, dewatering unit, mining tailings separation, etc.


5. GNLW554FT-VFD Decanter centrifuge
6. Screw conveyor GNSC14-12B with gratings cover, and addtional safety features: Full Length Safety Grab Wires along the auger, we could offer CNEX, ATEX, IEC EX for options.
7. 3 phase decanter centrifuge GNLWS364FT-VFD, it can be used to separate oil, solids and water. It is the major equipment for oil sludge separation system.


8. Shaker screens
9. 3 phase disc separator GNSD90, it can be used to separate oil, solids and water.

OBM Vertical Cuttings Dryer for Several Africa Customer

Recently several packages of OBM vertical cuttings dryer unit are delivered to several Africa customers. Some clients bought single drilling waste management equipments, including vertical cuttings dryer, decanter centrifuge, screw pump, screw conveyor, spare parts,etc. Some clients ordered the complete vertical cuttings dryer package, which including vertical cuttings dryer, decanter centrifuge with its feeding pump, telescopic skid for the vertical cuttings dryer and decanter centrifuge, fluids catching tank as an intermediate tank, the VFD control panel and feeding pump are installed on the telescopic skid for convenient transportation and operation.


Since 2012 till now, GN solids control has sold hundreds of OBM vertical cuttings dryer package to Africa clients for OBM drilling cuttings treatment and volume reduction treatment before feeding to Thermal desorption unit. With reliable working,long service life, easy operation and maintenance, GN vertical cuttings dryer and decanter centrifuge has got positive feedback from our clients at site, especially for the steadily working under hot weather in Africa.


GN vertical cuttings dryer has been updated to G version according to client’s feedback, the lastest version design has been the most user friendly and best performance, it is the ideal equipment for OBM drilling cuttings treatment. GNCD930G-GP vertical cuttings dryer working principal is that the motor drive the main pulley, the main pulley drive the gearbox cover via belt, the gearbox drive the bell jar assembly and screen basket assembly. Fix the gearbox input shaft, to make the gearbox output shaft speed lower than gearbox cover speed, to drive the rotor assembly in a lower speed than screen basket assembly speed. Then, the screen basket assembly and rotor assembly form same rotation direction separation machine with proper differential speed.
