Solids control is one of the very import link in the petroleum well drilling project, which is used solids control equipment to remove out the drill cutting from the mud, recycle mud and keep the property of mud. and the good mud can balance the pressure between inside and outside of well. and also protect the rig machine. Improve the rig drilling efficiency. Last week we delivered several sets Decanter centrifuge and screw pump for offshore drilling project.

In all solids control equipment ,Decanter centrifuge is the last stage for drilling mud processing. It can remove out the particle that smaller than 2o um, and clean the mud. GN have different models Decanter centrifuge according to the treating capacity ,GNLW452, GNLW363 are most used in the drilling project for mud treatment. For some big treating capacity, we will recommend 18 inch GNLW553 centrfiuge to customer. From the photo, we can see this centrfuge is a little difference with standard machine. It is used for offshore drilling, and has more strict requirement to lifting. As we all know, there is no forklift on offshore platform, so all equipment must weld the lifting eye. Sometimes end user will require the DNV lifting certificate. Centrifuge is one kind machine that utilize the rotate speed to generate the centrifuge force, and the different density solids and liquid will bear the different force, then the material will settle on different layer.
Except decanter centrifuge, We also provide centrifuge pump to customer. In drilling mud project, centrifuge pump is the most widely using pump. It is simple structure with stable quality. For the high density liquid transfer, centrifuge pump is the best optional for client.
GN solids control can provide the whole series solids control equipment, such as shale shaker, mud cleaner and also mud system , if your project have demand on our equipment ,please feel free to contact us.

GN Separation as one new brand of GN company, it main focus on the solids liquid separation industry. The separation equipment is not only limited the Decanter centrifuge ,shale shaker, we also design and manufacture the most efficiency separation and dewatering equipment to meet the market demanded.

Last week we delivered one screw press dewatering machine to units states customer. Screw press is one of the new machine of GN. We started to provide screw press to customer since 2019. Different with Decanter centrifuge, screw press is utilize the pressing force between move ring and fixed ring to squeeze the sludge to extrude the water included in sludge. Decanter centrifuge use the separation force generated under the high rotated speed, the different density material will bear the different separation force, and settle down on different layer. The solids will sink on the bottom and liquid above solids, through screw pusher to discharge the solids. Decanter centrifuge has the big treating capacity, the slurry sometimes do not need to mix flocculant. But the consumption of power is a litter higher, the discharged solids is not dry enough.
Screw press dewatering machine is lower power than Decanter centrifuge. It has the different model with treating capacity from 4kg/hour ~640kg/hour of dry solids weight. For customer, it has more optional to get the suitable model for their project. Low power is the most feature of this machine. such as the biggest model GNDL-404,which can process 133m3/hour and the total power is only 7.5kw. Simple structure made it easy to maintenance, actually only move ring and fixed ring need to replace after long time using. In most project, screw press dewatering machine need to run with chemical dosing unit, add flocculant to combine small particle into big one and then feed into screw press to dewater it.
GN can provide the customize separation and dewatering solution for your project, if you have demand on this ,welcome to contact us.

GN Solids Control has focused on separation and conveying area for more than 15 years. With the 15 years development ,we built our own brand GN solids control , and GN get the reputation from the market. Reliable quality and quick response help us win lots market and built long terms relationship with many top client in the world. We do not provide equipment, but also give the whole solution for the solids liquid separation and material conveying.

In our product line, except the normal pump for liquid transfer. We also developed GN solids vacuum pump this special type pump for high solids content material transfer and also for some solids power transfer. Different with normal pump, our vacuum pump was driven by high pressure. Utilize the air suction force and high pressure push force to suck and discharge material. All its component was driven by air include the pump valve. The normal type pump, such as centrifuge pump through the impeller to transfer liquid , but for high solids content material ,such as sludge ,drill cutting ,centrfiuge pump is useless. The solids vacuum can win this job.
last week, we delivered a vacuum pump to Asia customer, who use it to clean the waste pit. Using the pump to suck the sludge out from pit and transfer them away. In the vacuum pump , there is one venture structure, when high speed air through venture, the inside air of tank will be take away, and genera a vacuum space inside of tank. This the source of suction power. After the tank suck full sludge, through switch valve, the high speed air will directly input pump tank, the high pressure air will push the solids out of tank, and discharge them out. As usually, the pump can transfer most kind material with a little liquidity, and the most transfer distance can reach 500 meters . For some low density liquid, the distance even can reach 1000 meters.
This pump can solve most your transfer problem of high solids content material. If your have demand on it, welcome to contact us.

Solids vacuum pump is one of the most featured equipment of GN solid control company. Different with other pump, this pump is driven by high pressure for the high solids content material transfer. Last week we completed the manufacture of vacuum for drilling waste handing.
Drilling waste main include the drill cutting discharged from shall shaker,or Decanter centrifuge. It more likes sludge, the normal pump is no way to transfer them because the low liquidity. especial the oil base drill cutting, which is high viscosity. The vacuum pump can directly suck them and transfer them in long distance. The suck power is provided by the vacuum condition of pump tank. The venturi structure of pump will suck out the air inside of pump tank and generate a vacuum space, and then the pipe can suck material through the pipe. After the pump tank filled enough material ,the air will fill into pump tank , and push the material out of pump and discharge out.

Except the high solids content sludge, GN vacuum pump almost can win the transfer of some powder material ,such as sand, metal power etc. The install position is not limited by explosion proof, because there is no electrical component in the pump and all was driven by air.
For currently, we have 4 models with different transfer capacity, they are 40B,20B,10B and 05B. The number of each model standard the transfer capacity of water in one hour. For example, the 40B means the pump can transfer 40m3 clean water in one hour. However the actual capacity is vary, because the material viscosity, liquidity ,solids content and also solids size all these will affect the pump performance. Sometime the altitude also affect pump, because the air pressure of high altitude is lower, which means the pump suck power will be weak.
If your project have demanded on these equipment, welcome to contact us. We will be pleased to quote.

GN solids control was funded on 2005, after more than 17 years development, GN has accumulated lots experience on the solids control industry for the drilling mud treatment, and we built long terms relationship with lots customer from all over the words. As long as our development, we use our equipment not only the oil gas industry ,but also the other industry ,such as environment protection, mining industry, water treatment, chemical industry etc. Currently, we have one set oil contaminated soil washing system is in manufacturing for middle east customer.

In the waste management and treatment , oil soil is one of the hardest material for treatment. As usually, it is oil water solids the 3 phase separation, and the oil is hard to separated out from soil. However it is very necessary to treat this kind polluted soil. This system include these main part: solids vacuum pump, soil washing separation, separation equipment, centrifuge equipment, and dewatering equipment.

Solids vacuum pump is used to transfer this high solids content sludge , the normal pump is not workable to pump this kind material. GN vacuum pump is driven by high pressure, and through the vacuum to suck material and discharge material by high pressure. When treat this kind material, firstly we need to washing the soil through the water, which can reduce the solids content, separate off the oil from solids, meanwhile we will mix chemical and heat material to make this separation easier. After that we will transfer this slurry into shale shaker to remove out the big particle size, and then the discharged liquid will be transfer into Decanter centrifuge to remove out the particle between 20-60 microns. After the 2 steps separation, liquid will be feed into disc centrifuge for the oil water and solids separate. Finally ,we can get the clean oil and clean water for reusing in the system.
If your project have demanded on these equipment, welcome to contact us .
