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.

This week we shipped 1 unit of 350gpm mud cleaning system to UAE for HDD project. This is GN standard design of 350gpm mud recycling system, wit compact design, multi function, mixinig, cleaning, storage.

The technical configuration is as below:
A double deck shale shaker with 6ea of 4inch desilter cone, this is GN unique compact design to save the cost for the client, and make the complete mud system suitable for the limit area of the HDD contractor. The top layer of the double deck shale shaker as the mud cleaner to dry the separated solids , the bottom layer of the shale shaker as the coarse solids shale shaker, the 4 inch desilter cone is made of polyurethane material for abrasion resistance and longer service life.

If add 2ea of desilter cone on this system, it can be used as 500gpm mud recycling system by just changing the desilter feeding pump from 22kw to 37kw. The mud tank size and road transportation dimension are totally same.
Except for such compact design with cheaper price, we also provide customized design mud recycling system to meet the different requirement of our client. For example, for 350gpm, a separate 2 panel shale shaker with a 2 panel mud cleaner with 6 ea of 4” desilter cone.
The mixing hopper with mixing pump are installed on the mud tank to mix chemical additives with the bentonite.
For 500gpm mud recycling system, most of clients require the design of 1 ea shale shaker with 1 ea mud cleaner（ with bottom shale shaker, 1 ea desander cone, 8 ea of desilter cone, the composite material frame shaker screens are installed on the shale shaker, mud cleaner for longer working life and better performance, and it can be storage up to 5 years.
If you require HDD mud recycling system, pls contact with GN solids control.

This week GN shipped 3 units of mud gas separator to France, last week we shipped 3 units of same poor boy degasser to CNPC. The mud gas separator is also called poor boy degasser, it is applied to separate the hazardous gas from the gas cut drilling mud before feeding to the shale shaker, the primary equipments of the solids control equipments.

The mud gas separator is normally installed beside the solids control system, close the well head, the flare ignitor will be connected with the gas discharge pipe of the poor boy degasser, and fire the separated gas in the remote area.
The mud gas separator is skid mounted, installed with chock manifold, it is normally used for deep drilling rig or other drillings, like geothermal drilling, coal bed methane drilling, mining exploration, gas drilling, etc. The fluids discharge line is connected with the mud flow divider or called possem belly inlet, there is bypass valve so the mud can flow to shale shaker directly bypass the mud gas separator.
The mud gas separator can separate the hazardous gas like H2S from the gas cut drilling fluids to protect the shale shaker from damaged. The vacuum degasser or centrifugal degasser will be installed on the solids control system mud tank, it also separates the gas from the drilling fluids to keep the drilling mud balance and protect the centrifugal pump.
The basic solids control system including shale shaker, desander, desilter, feeding pump, vacuum degasser, decanter centrifuge, mud tank, pill tank, trip tank with trip pump, reserve tank, mud mixing unit, etc. For customized solution of mud pit and solids control equipments, pls contact with GN solids control.
We also provide complete solution for drilling waste management system as a zero discharge system, the recycled mud can be reused by the drilling rig, the cuttings can reach the limit of landfill or send them to further process of TDU.
