GN Soil Remediation System

GN Solids Control is a solids and liquid separation system turn-key provider. This year, GN Solids Control has provided 3 sets of large soil remediation system. Basically, one GN Soil Remediation System is including the following components: 20170704 Oil Sludge Treatment 2
1. GN Feeding Hopper
A large feeding hopper will be used to catch the soil slurry first. GN Solids use steep side angle walls so that wet and sticky soil falls to the bottom of the hopper easily. Across the top of the hopper, a bar grate to keep large, oversize material from entering the hopper and plugging the hopper.
2. GN Screw conveyor
GN screw conveyor transports the soil from the bottom of the hopper to the Shale Shaker Screener. Screw conveyor should be the proper angle and length to empty the soil feed hopper and discharge on to the Shale Shaker Screener.
3. GN Shale Shaker
GN Shale Shaker will remove gravel and stones and oversize debris. Different size screens will be assembled on the shaker. High pressure water spray nozzles are fixed on the shaker deck in order to wash the soil through the screens. The Shale Shaker is positioned on top of a mixing tank. Usually, GN Hi-G force shaker GNZS594 will be used to treat the slurry. Vibration motors are using USA martin or Italy OLI. 20170704 Oil Sludge Treatment 3
4. GN Mixing Tank
The mixing tank should be approximately 7000 liters. It needs a robust, strong mixer. It needs steam coil piping in the interior of the tank to heat the soil slurry. Operating temperature is normally 70 C.
5. GN Slurry Pump
The Slurry Pump should be a centrifugal pump. It will transfer the soil slurry from the mix tank to the following treating equipment.
There are some other equipment will be used. If you want to learn more, welcome to connect with GN Solids Control.

GN Solids Control Explosion Proof Standard Equipment

GN Solids Control is a top manufacturer of solids control equipment and waste management systems. As one of the key industries that use GN Solids Control equipment, Oil and Gas area is one of the most widely used one.
GN Solids Control is an expert to provide tailored mud systems based on customers’ particular demands. Now GN Solids Control product line includes: shale shaker (or Hi-G force shaker), De-Sander, De-Silter, Mud Cleaner, Decanter Centrifuge and Cuttings Dryer. Besides the above standard treating equipment, GN Solids Control also provides wearable products like shaker screens, hydro-cyclones (4inch and 10 inch )etc. By word of mouth, GN Solids Control won great reputation in the world, and until now customers from over 70 countries are using GN solids control and waste management equipment. 20170704 Oil Sludge Treatment 3
As it’s known to all, solids control and waste management equipment need to be explosion proof certificated in order to use in the oil and gas area considering the harmful air or dust in the drilling rig site.
According to ATEX Directive 99/92/EC or ATEX 137 Workplace Directive, it gives us the definition of different levels of dangerous drilling rig site environments. ATEX is classified into ATEX Zone 0, ATEX Zone 1 and ATEX Zone 2, the smaller no it has, the more dangerous it is. So ATEX Zone 0 is the most dangerous classifications which need to be pay great attention.
In many drilling rig sites or workplaces which may produce or contain explosive atmospheres, this is includes explosive air (gases, vapours and mists) and explosive dusts. In order to tell the difference of explosive dusts, ATEX is also classified into Zone 20, Zone 21 and Zone 22.
The explosive air is directly related to drilling rigs, oil & gas platforms as well as storage facilities. So usually when GN provides explosion proof standard solids control and waste management systems to drilling customers, we need to know what explosion proof standard suit for customers.

GN Decanter Centrifuges for Canada Customer

GN Solids Control has been manufactured thousands of decanter centrifuges since the very beginning. As the leading decanter centrifuge provider, GN Solids Control is only using top quality materials. By word of mouth, more and more customers are getting to know GN Solids Control.
GN Solids Control is an expert to provide solids and liquid separation equipment: decanter centrifuge, cuttings dryer, hi-G shaker etc are all GN core products. GN Solids Control is also good at providing a turn-key solution based on customers’ special demands.
GN Solids Control has been selling decanter centrifuges in North America for some years. Many decanter centrifuge manufacturers are using GN decanter centrifuges for separating solids and liquid. Several weeks before, GN Solids Control delivered 2 sets decanter centrifuges for one Canada customer, includes one 22inch rotating centrifuge GNLW553 and one 14inch rotating bowl centrifuge GNLW363.

1. GN 22inch Centrifuge
22 inch rotating bowl decanter centrifuge is the second largest one that GN Solids can manufacture. 30 inch centrifuge is also can be provided for larger volume treating.
GN 22 inch centrifuge is using duplex stainless steel 2205 (or stainless steel 2304). In order to have a good wear resistance, GN Solids Control is using tungsten carbide tiles and fixed them along the screw propeller. Solids discharge ports are also protected by tungsten carbide inserts or special ceramic.
On the two ends of the centrifuge, GN Solids Control is using genuine SKF bearing, which is easy to get in North America.
2. GN 14inch Centrifuge
14inch centrifuge is the most common used centrifuge for slurry separating. Treating volume is around 130GPM.
These 2 centrifuges will be used to treat the waste water or soiled slurry. GN Solids decanter centrifuges can also be used to treat oil and gas drilling waste, industrial water treating, hrdro-vac wastes etc.

GN Oil Slurry Treating Unit For USA customer

GN Solids Control just finished the setup of one whole oil slurry treating system for one USA customer several weeks before. This whole treating unit was delivered to Middle East as they had won a project to treat one large oil slurry pit for Chevron.
Now this GN Oil Slurry System was setup and ready for connecting with electricity and water pipes and heating pipes. GN Solids Control sent one Electrician and one Mechanical Engineer to guide customer to setup this oil slurry treating system. GN Solids Control is especially good at manufacturing customized solids control and waste management systems based on customers’ special demands. This whole oil slurry treating unit is designed and manufactured after discussed with our USA customer thoroughly. It’s especially used to treat large density and high viscosity oil slurry, such as refinery oil, raw oil storage in tank bottom: oil, water and solids can be separated out as a 3 phase treating system.

20170704 Oil Sludge Treatment 1
Here are the main treating components in this GN Oil Slurry Treating System:
1. Premix and Heat Tank
Oil slurry can be pumped to the premixing and heating tank with a GN vacuum pump. After treated, the original raw slurry is thinned and has a good running feature.
2. Shaker Tank
Shale shaker is used to eliminate all those large solids. GN Solids Control also manufactures its own shaker screens. Some other replacement screens for Derrick, Mi-Swaco, NOV etc can also be manufactured. 20170704 Oil Sludge Treatment 2
3. Centrifuge
Decanter centrifuge is one key treating equipment to separate those finer particles. GN Solids Control also provides flocculent system in order to separate out those very finer solids.
4. 3-Phase Treating Skid
This 3-pahse treating skid is composed by GN Slant Clarifier, GN Oil &Water Separator and GN Storage Tanks (water tank and oil tank).
More info will be shared after this system running for a while. If you need any oil slurry treating system, feel free to connect with Thomas@gnsolidscontrol.com.20170704 Oil Sludge Treatment 3
