As a manufacturer of solids control and waste management equipment, GN Solids Control has the complete production line for fabrication the equipment from raw material of steel cuttings, bending, to lathe processing, then to coating process. At every procedure, GN adopts the up-dated fabrication machine to ensure the quality and efficiency. Recently, GN just upgraded the painting workshop appliances for purpose of both efficiency increasing and environmental protection.

Automatic shot blasting machine – shot blasting machine is used to working piece surface cleaning up and strengthen. It can remove the burr and rust of the casting, so that the subsequent painting process would be performed well.

Constant temperature spraying – In order to increase the paint coverage area on the working piece and outer surface painting quality, GN set up the dust-free and airless painting line. Airless painting machine applies high pressure on the paint, and then the paint was sprayed out via the spray gun as fog style. It can spray the paint to all points of the working piece where the brash will not reach. The thickness of the spray painting is uniform and the consumption is less. Constant temperature would speed up the drying process even in winter.

Electrostatic spraying – the material used in electrostatic spraying is the plastic powder. As the powder coating material has no solvent in it, it will not produce waste of water, gas and solid stuffs. Thus the electrostatic spraying technology is developed fast and nowadays widely applied. Electrostatic spraying also has advantages of high efficiency, suitable for automatic production line and coating powder recyclable.

With a series strict regulations issued on environment protection, many factories stopped their painting job. GN Solids Control is pleased to accept outsourcing painting service with precondition of completion of GN own painting job.

This week, GN’s fabrication department was busy finishing the final assembling of 2 sets containerized cuttings dryer systems for Russia client. Containerized design is especially for application in the low temperature area. Operators could work inside the container without bearing for the cold weather. Equipment could also be protected in warm place.
So far, GN has ever sent more than 10 units this type system to Russia. In the process of fabrication this kind of containerized cuttings drying system, GN accumulated lot of experience in equipment layout inside and what equipment will be needed to make the system works well.

 

Cuttings dryer is the main equipment in the system. The dryer is installed at one end of the container. At this part, the container is designed with open top cover. A hopper is connected with the feeding port of the cutting dryer for collecting the drilling cuttings. Beside the dryer unit, a cantilever crane is installed there for repairing purpose when lifting the upper part of the dryer.
Effluence discharged from the cutting dryer gravity flows into the collecting tank in the middle part of the container. On the tank, a mud agitator is installed for blending the fluids to prevent the solids from settling to the tank bottom.
A screw pump for feeding to decanter centrifuge is also installed inside the container for easy connecting with the collection tank. This tank is used to transfer the recovered drilling fluids from collection to tank to out connected decanter centrifuge for polishing. After treated by the decanter centrifuge, the drilling fluids could be reused.

 

For operators’ convenience, the container is also equipped with washing platform with clean water pipeline connecting port and cabinet for tools and small wear parts storage.
Now these 2 set containerized drilling cuttings treatment system are under the final assembling procedure, after that, all the equipment would be tested for trial running. GN has already contacted the shipping forwarder for preparation of delivery of the system. For more information on the system, please feel free to contact with GN.

 

Tunnel boring machine is an important machine in the city construction project like subway and pipe laying. In order to bring out the cutting and lubricate the drill bit of the tunneling machine, the operators need to add large quantity water or drilling fluids into the drilling well. For cost saving, the operators also have to think about reusing of the drilling fluids. Mud recycling equipment is mainly used to recycle the drilling fluids and remove the cuttings. Shale shaker, de-sander and de-silter could respectively separate the coarse solids, sand and silt. For fine solids, the decanter centrifuge would be needed.

After several time recycling, the specific gravity of the drilling fluids would be higher and higher due to the built up of ultrafine solids that even cannot be removed out by using only the centrifuge unit. Operators need to add chemicals into the drilling fluids and then do the dewatering process.  Dewatering centrifugepackage includes 2 parts: chemical dosing system and big bowl decanter centrifuge unit. The units ready for shipping to Singapore is designed containerized with both the centrifuge and dosing unit are put into the 20 feed container for easy transportation and jobsite safety purpose.

GN’sdosing system is consisting of powder feeding hopper, powder transferring screw, mixing tank and discharge pump. The screw is PLC for accurate metering of the powder. Mixing tank is divided into 3 departments for flocculation powder mixing, curing and storing. The mixing procedure is also PLC for automatic convenience. Before the drilling fluids fed into the decanter centrifuge, the flocculation agent is firstly mixed into the fluids to gather the ultrafine solids. Thus the decanter centrifuge would remove the floccule from the drilling fluids.

 

Removing the ultrafine solids from the drilling fluids greatly reduces the consumption of water and increase the drilling efficiency. The dewatering centrifuge package can also be used inoil sludge treatment project for oil recovery.

These days, one of GN’s engineers is busy on commissioning of the mud cleaning equipment sent to the site where a client from The States want to use these equipment to clean the waste mud produced in construction project. So far, all the equipment have been well connected, next, GN’s engineer will help to test running of the equipment and train client’s operator how to use GN machine. This client totally order 2 set mud cleaning system from GN, GN hopes the performance of the machine would satisfy client and brought profit for client as soon as possible. The ordered mud cleaning system is consist of several separation modules and related auxiliary equipment, below is a brief introduction on the system.

1. Trash collecting hopper – construction waste is delivered to site and then firstly mixed by water to make the waste flowable. At the bottom of the hopper, there are valves for discharge the waste onto a coarse screen for large size particles. This hopper is installed underground for easy waste discharge from the truck.  2. Coarse screen — the coarse Screen under the hopper would remove the trash like debris, cans, metals etc. The collecting tank under the coarse screen is used for temporally storing the liquid that would be treated further by the fine screen.  3.High G drying shaker — On one mud tank, GN’s high G force drying shaker is fixed on the first compartment of the tank. The liquid pumped from the tank beneath the coarse screen will be separated again by the drying shaker for fine particles removing and water recovering. For better performance, GN’s shaker is fixed with composite frame screen panel and oil resistance rubber seal strip. This extends the continuous working period and reduces the maintenance frequency
2. De-silter unit — The de-silter is assembled equipment by cyclone frame and under drying shaker. The cyclone unit could reduce the cut point down to about 20 microns for much finer solids separation. The under drying shaker is same model with the high G force shaker for maintenance convenience.  5. Big bowldecanter centrifuge — the decanter centrifuge is provided with telescopic skid. The slurry treated by the cyclone unit would be fed to the centrifuge for polishing. The ultrafine solids cannot be removed even by high speed decanter centrifuge. Thus, GN equipped dosing system that is used for mixing the flocculation agent. By adding the flocculation agent, the ultrafine solid particles would be gathered and separated by the centrifuge unit

All equipment is provided modularly for easy connection and installation. Per specified request, clients could choose all or several of the modules. For further information on this project, please pay constant concern on GN Solids Control.

Couple months ago, one client ordered decanter centrifuge and centrifugal pumps from GN solids on their jobsite in Canada for oil sludge treatment. Oil sludge would come from the drilling site oily waste cuttings, oil storage tank bottom sedimentation flushing slurry and refinery plant oily waste.
GN has decanter centrifuge designed especially for the oil industry. After few years’ development, the centrifuge unit was approved qualified in solids control fine solids separation, drilling fluids recycling and oil recovery from waste oily sludge.

Before the decanter centrifuge, the client already had the shaker unit for coarse solids separation. This thick oily sludge would be mixed with chemicals firstly in a steel tank for demulsification and viscosity reducing. But only using the shaker unit cannot remove the fine solids in the slurry. After sufficient communication and factory visiting, the client fully know the capability about GN’s decanter centrifuge, finally they order two units from GN.
One of the two centrifuges is 14 inch with max speed up to 3900RPM. This is GN’s most popular model for oil industry. With a high speed, this unit can remove the ultrafine solids from the slurry if adding flocculation agent. The other unit ordered is GN’s big bowl centrifuge with 22 inch diameter rotation bowl; this unit is used to remove the large content solids as its high flow capacity.

Shortly before, GN upgraded the centrifuge bowl material by using stainless steel of 2304 with much better features on corrosion resistance. Centrifugal casting technology makes the bowl body with better balance performance. Both of the units are equipped with VFD control panel for various working condition and client’s multiple purpose. GN is also able to provide the skid for centrifuge to put on for a convenient performance.

GN always makes inventory of decanter centrifuge in case of any urgent request from clients. Welcome to GN for business negotiation and factory capacity inspection.control, and now the centrifuge unit are working

After few months’ documentation preparation and request following up, GN finally was awarded the tender of solids control equipment for 16 drilling rigs in Ukraine. Client is planning to upgrade the existing mud recycling system by replacing the old equipment. This tender includes over 30 units decanter centrifuges, over 30 units shale shaker and mud cleaners, as well as 6 units vacuum degassers.
Below pictures shown is the second batch equipment ready for delivery.

Shale shakerand mud cleaner are the equipment use to remove the large size drilling cuttings in the drilling fluids. GN’s shale shakers model of GNZS594E-HB which is especially designed for the oil and gas drilling with weir feeder to buffer the high pressure impact for protecting the shaker screen. The screen deck of the shaker is adjustable from -1°to +5°,operator could even adjust the shaker deck during running of the shaker. With the G force up to 7.5, the shaker could greatly dry the solids for drilling fluids recovering. The cyclone manifold is bolted fixing on the shaker unit and could be removed for easy transportation and installation.

Vacuum degasserunit is installed after the shale shaker and before the mud cleaner. It is used to remove the gas in the gas cut in drilling fluids. By removing the gas, the vacuum degasser could ensure the drilling fluids with a proper gravity. And the centrifugal pump could transfer the drilling fluids to the cyclone unit with sufficient pressure.

Decanter centrifugeis used to remove the fine solid particles in drilling fluids. The client equipped 2 unit centrifuges for each of the drilling rig. When drilling, the decanter centrifuge with low speed could be used for barite recovery, and the other centrifuge with high speed would be used for ultra-fine solids separation.

The ordered equipment is the tender would be divided into 4 batches for delivery. The remaining units are still under fabrication progress. Please pay attention on GN solids control for latest news on delivery of this order.
