GN engineer team just back to China from Singapore client’s site, for the commissioning of GN dewatering centrifuge system, the project is to separate big solids from the waste sludge/ water of Tunneling and recover the water, the solids is qualified for landfill or disposal, since the using of water is very expensive for tunneling, the client prefer to reuse it by the dewatering centrifuge unit.

The technical configuration is as below:
VFD decanter centrifuge with feeding pump installed into the 20ft container, together with flocculation system for convenient operation and rain proof, sun proof.
GNLW363C-VFD is the best sold model decanter centrifuge, it can be widely used for dewatering unit, solids control system, drilling waste treatment system, oil sludge separation system and all other industry waste water treatment project. The positive pressurized VFD control panel with self-cooling tube or air conditioner can allow the equipments working in high temperature weather like Middle East. The converter of the main motor, back drive motor and pump motor are all ABB brand, and the centrifuge screw is protected by tungsten carbide tiles for longer working life.

The flocculation system is customized as per the chemical adding technics of the client. The mixing tank is made of stainless steel for anti- corrosion.

GN solids control will ship 2 units of VFD decanter centrifuge to India drilling company next week. They are for ONGC project. GN provide all the documents and parameters as per the tender requirement and finally got the tender.

The ATEX certificate for positive pressurized VFD control panel and motors are installed with the GNLW453 decanter centrifuge are suitable for 460V/60HZ, 3 phase and for zone 1 application. The main components and the cabinet is imported from Europe by air. The centrifuge with offshore lifting pad, we can get DNV certificate if required by the client. The centrifuge painting color is customized by the client.
We choose screw pump as the centrifuge feeding pump, the motor is also ATEX certified 460V/60HZ, 3 phase for zone 1 application, the flow rate can be adjusted by the VFD converter by control the frequency. Centrifugal pump and submersible slurry pump can be also used as feeding pump of decanter centrifuge, but they are not effective to control the frequency to adjust the flow rate, we suggest to use valve to control the flow rate.

GN solids control shipped containerized drilling waste management system to Russia this week together with several units of high G force drying shaker.

The containerized drilling waste management system including the equipments below:
1)    Vertical cuttings dryer with flashing pump
2)    VFD decanter centrifuge with feeding pump
3)    Screw conveyor to collect the discharged solids from the vertical cuttings dryer, the oil in the cuttings is below 5%, can meet the disposal limit in most of countries

4)    Fluids collection tank to collect the discharged fluids from the vertical cuttings dryer and feed to the decanter centrifuge
5)    Container with insulation layer to keep the drilling fluids warm during winter when the temperature is minus 40 degrees in Russia area, windows, doors are opened for convenient operation and maintenance.

The containerized drilling waste management system has been widely used in Russia for many drilling fluids service companies and drilling companies because of the cold weather there, so that the client can keep working during the long winter.
The vertical cuttings dryer GNCD930 and decanter centrifuge GNLW363CG-VFD is the major equipments for drilling waste management system for oil based drilling cuttings. If only the clients do the maintenance as per our instruction and the operation manual, and GN engineers will fly to the client’s jobsite to train the client’s engineer and do the first time installation and commissioning if required by the client. We also suggest all the clients to prepare 2 years operation spare parts in case of the wear parts need to be replaced.

GN solids control will participate in the OTC 2018 as usual and show our most advanced equipments there.
GN OTC stand information as below:

Show Time & Location: 30 April – 3 May, 2018. NRG Park, Houston, Texas, USA
Booth No. 1: NRG Center 1369-1 (GN China)
Booth No. 2: NRG Arena 8000 (GN America)
One stand will show the equipments in the name of GN solids control, the other stand will show in the name of GN solids America LLC, which is our brand company in Houston, TX.
We will show the equipments as below:

Decanter centrifuge GNLW363C, decenter centrifuge can be applied for oil sludge separation, drilling waste management system, solids control system, dewatering unit, etc.
Shale shaker: GNZS594F-HB , the 4 panel shale shaker installed with 4pc GN composite material shaker screens, screen dimension 585x1165mm, the screen area is 2.73m2, the vibration motor is 2.3HP Martin brand vibration motor made in USA, The shaker deck bottom is made of stainless steel which is fluids touch parts.
Sludge Vacuum pump: GNSP-20A, slurry pump is used as transfer pump for drilling cuttings, dredging slurry, all kinds of oil sludge based on density and viscosity. We need to confirm if the vacuum pump can be used to transfer oil sludge based on the density, viscosity, depth, pressure,etc.
Mud cleaner: GNZS594E-2S12N

Centrifugal pump
