Decant centrifuge in North America

BY gnadmin 5 July 2018 decanter centrifuge

GN Solids Control is one of the largest solid control and waste management companies which specializes in manufacturing the related equipment, such as shale shaker, desander, desilter, mud cleaner, vacuum degasser, mud gas separator, decanter centrifuge, agitator, centrifugal pump, cutting dryer, screw pump, shear pump, mud gun and so on. After 10 years development, GN has promoted its products to over 60 countries and now it also established two overseas subsidiaries, US and Russia.

Recently we have been forced our main work force on pushing our Decant Centrifuge into the North America Market. So far we have got many good feed back from different end users in both The U.S and Canada. Our decant centrifuge system works in many different environment, . They can be working at super hot desert environment. The VFD control system is provided by SIEMENS or ABB. All the bearings applied in the centrifuge are from SFK premium bearing which can guarantee longer operation life and more reliable operation. All the motors and control panels are explosive proof and certified to work in zone 1 and zone 2 hazardous area. The 553 decanter centrifuge will become the star products for processing large volume of liquid and solid separation job. More and more customers are showing great interest in it. Also for many different industries, they have also chosen our decant centrifuge to be their first option of solids separation. Now GN can not only manufacture its traditional 363 centrifuge with 14 inch bowl, but it can also make larger bowl size, GNLW553, whose bowl size is 22 inch. This equipment can be applied in the processing the water based mud, in the oil based mud system, in dewatering and in recovering barite. There are also some great features for this equipment: it is VFD controlled and can offer the operators a variety of solutions for the changing field operation situations.

That’s the basic introduction of the large bowl decanter centrifuge 553. Hopefully it will be useful to you. We will try our best to assist your business to be successful. Welcome to visit www.gnsolidsamerica.com and please send your inquiries to USA@gnsolidscontrol.com

GN dewatering centrifuge for Tunneling in Singapore

GN dewatering centrifuge is working well for Tunneling in Singapore, our engineer just finished the first time installation and commissioning there and back to China. As per client’s request, our engineer can fly to the client’s site to support them for the first time installation, commissioning and training. If the equipments will work well or not, it will mostly depend on the proper maintenance and operation, we will train the client’s engineer how to operate it and how to do the maintenance.

The dewatering centrifuge system for Tunneling is to treat the waste mud / sludge/ water and reuse the water, the discharged solids should be dry enough to collect by bags then shipped by truck. The configuration is as below:
1) GNLW363-VFD decanter centrifuge is widely used for dewatering unit to treat the waste water
2) Chemical dosing system/ flocculation system
3) 20ft container with windows and doors.
4) Netzsch brand screw pump as the feeding pump of decanter centrifuge, which is the ideal feeding pump to control the frequency to control the flow rate, compared with centrifugal pump and slurry pump, it works more steadily.

Before feeding to the decanter centrifuge, we suggest the client to use a screen/ filter or high G drying shaker / desander / desilter before the dewatering centrifuge system, the purpose is to prevent course solids enter into the centrifuge and the screw will be damaged and centrifuge will be blocked. The core components of the centrifuge is the screw, GN centrifuge screw is completely made by stainless steel, and protected by tungsten carbide tiles, the fluids distribution port is protected by tungsten carbide alloy for wear resistant.

2 units of decanter centrifuge ready for shipment

BY gnadmin 18 March 2018 decanter centrifuge, solids control, VFD control centrifuge

This week 2 units of VFD decanter centrifuge ready for shipment to India for ONGC project in GN factory. The clients ordered 2 units of GNLW453C-VFD with screw pump for their solids control system with their customized painting color.

GNLW453C-VFD centrifuge with 18inch bowl and 61inch length, the max G force is up to 2578G, considering the high temperature in India, the positive pressurized VFD control panel with air conditioner for cooling, in some countries with environmental temperature less than 40 degree, the VFD control panel attached cooling tube for cooling. The frequency converter of the main motor, back drive motor and pump motor is all made of ABB brand, the other electric components are also world famous brand like Siemens/ schneider/ ABB, the motor and VFD control panel are all ATEX approval and suitable for 460V/60HZ, 3 phase and apply for zone 1 application.
Features of GN decanter centrifuge:
1) Different with other Chinese centrifuge manufacturer, GN use SKF bearings, since bearing block is the most important part for centrifuge, we use more reliable brand bearing to improve the centrifuge working life and reduce maintenance cost.
2) The screw is completely made of stainless steel, the impeller is protected by tungsten carbide tiles, the fluids distribution port is protected by tungsten alloy and interchangeable.

GN Containerized Drilling Cuttings Treatment System and Shale Shakers for Russia

BY gnadmin 10 March 2018 decanter centrifuge, drilling waste management, VFD control centrifuge

This week GN shipped one set of containerized drilling cuttings treatment system and several units of shale shaker to Russia. This is not the first containerized drilling cuttings treatment system sold to Russia, because of the low temperature in Russia area, the client do not want to stop operation in the long winter, this customized design is to keep the drilling fluids warm and prevent it from get frozen.

The containerized drilling cuttings treatment system including one unit of vertical G dryer with fluids collection tank, one mud agitator installed on top of the collection tank. The centrifuge feeding pump transfer the mud from fluids collection tank to the decanter centrifuge to separate more solids from the fluids, the final discharged solids can be reused for the drilling rig or used to prepare for new drilling fluids. The solids discharged from the vertical G dryer is with OOC < 5% like powder, they will be transferred by the screw conveyor to the cuttings box outside the container. One unit of 4kw screw pump is used as flashing pump of the vertical G dryer. The whole drilling cuttings system treating capacity is 40m3/h for oil based drilling cuttings, the decanter centrifuge with VFD control panel can be used to separate the fine solids from the fluids, the separation cut point is 2~5 microns.

The client also ordered several units of GNZS594 shale shaker with 4 panel composite material frame shaker screens, the screen size is 585x1165mm, the total screen area is 2.73m2, the G force is high up to 7.5G.

What equipments will GN show at OTC？

Decanter centrifuge GNLW363C, this is the best sold model decanter centrifuge among all the decanter centrifuge models.
Shale shaker: GNZS594F-HB, we have many sets of shale shaker and mud cleaner in stock in Houston warehouse for immediate shipment, we install Martin brand vibration motor made in USA and assembly in our warehouse.
Sludge Vacuum pump:GNSP-20A, this is our new products in 2018, we have sold GNSP-40A vacuum pump for drilling cuttings transfer and dredging slurry transfer for dredging slurry separation system, sometimes the vacuum pump may not be suitable to transfer the oil sludge based on the sludge density and viscosity and the depth. GNSP-10A & GNSP-20A vacuum pump is the new designed model to meet the client’s requirement for smaller treating capacity.

Mud cleaner: GNZS594E-2S12N
Centrifugal pump, the installation dimension, outer dimension and spare parts are all interchangeable with Mission Magnum centrifugal pump.
