Leave a reply

GN Solids Control is the top 1 manufacturer for solids control and waste management systems. As one of the core products, GN Solids Control manufactures decanter centrifuges which can be used in varieties of industries’ slurry treating.
Now GN Solids Control decanter centrifuges include: 9 inch rotating bowl centrifuge, 12 inch rotating bowl centrifuge, 14 inch rotating bowl centrifuge and 22 inch rotating bowl centrifuge. And GN newly developed 30 inch rotating bowl decanter centrifuges are also being used for large volume slurry treating.

At first GN Solids Control designed the 30 inch rotating bowl decanter centrifuge to meet the needs of Tunnel Boring Machine drilling as well as Soil Remediation. With the increasing inquires, GN Solids Control 30 inch decanter centrifuges can also be used in HDD drilling.
It well known that solids control equipment such as shale shakers, desanders or desilters are usually used for the HDD mud treating. GN shale shaker is mainly used to separate the solids larger than 100 microns, while desander fixed with 10 inch hydro cyclones are used to separated out solids larger than 50 microns, and the desilter fixed with 4 inch hydro cyclones are used separated out solids above 25 microns. The after treated mud can be reused and pump into the HDD rig for drilling. Before, there was several HDD drilling companies use decanter centrifuge as they thought solids smaller than 25 microns can be ignored. However, according to the recent surveys, it is these smaller size solids that much more harmful for the HDD drilling rig. Just take one example in Australia: one of GN Solids customers is only use GN shale shaker and GN desilter in the mud treating system. After we recommend to use on decanter centrifuge, they found the drilling efficiency has increased 20 ~30%. And the former push back problems of the HDD rig have never happened after the centrifuge is used.
GN Centrifuge is especially used to separated our solids large than 2 microns. The former working method just use shaker and hydro cyclones need to be revaluated. It’s trend to use decanter centrifuge in HDD drilling.

GN Solids Control has been designed and manufactured various solids control and drilling waste management systems. As customer’s demands keep changing, more and more strict rules for waste or slurry management are arising which need equipment that is more professional. Today, we would like to introduce one set of tank cleaning system that is used to provide recycled clear water to clean the oil tank, slurry tank or chemical tank etc.
GN Automatic Tank Cleaning System (GNTC-30B) is one continuous cleaning system: clear water tank volume is 7.5m3 and slurry treating capacity is 30m3/h. This is one compact designed system which is 3500mm (length), 2800(width) and 3200 (height).
GNTC-30B tank cleaning system working process:

gn-tank-cleaning-system-2
1. Centrifuge pump suck clear water from the triangle tank and feed to the high pressure washing device. The high pressure washing device clean the inside tank.
2. Cuttings pump feed the after washed slurry into GN 4 inch desilter cyclones. One filter device is assembled between the cuttings pump and the tank so most of the large solids can be filtered.
3. GN 4 inch cyclone separates the finer particles which are pumped to one cuttings box. While the liquid discharged from the cyclone is feed into one slant clarifier.
4. Slant clarifier is fixed with many pieces of thin metal plate with a certain angle. By using gravity, there are some solids fall off to the tank bottom and will be transported by a small screw conveyor. And the overflow water is relative clean which can be used in the high pressure washing system.
By using GN tank cleaning system, customers will be able to save large volume of water when clean tanks. This system is especially suitable for the offshore tank cleaning due to the pretty compact structure. GN Solids Control provides explosion proof motors and electrical components on this tank cleaning system. DNV certification can also be provided.

GN Solids Control just developed one set of automatic Tank Cleaning System which can be used to treating the oil tank bottom sludge continuously. Now there have been several sets are used in the worksites.
GN Tank Cleaning System treating capacity is 30m3/h, it mainly includes the following two parts:
1. GN Surge Tank
GN Surge Tank stocks the water up to 7.5 m3/h. Water is pumped to the tank by one centrifugal pump, it’s used to clean the tank bottom under high pressure as those sludge need to be washed and diluted before feeding into the desilter cyclones.

gn-tank-clean-system
GN Cuttings Pump is used to feed into the desilter cyclones. There are 6 sets desilter cyclones assembled on the top of the tank. As we know, the desilter cyclones are take advantage of the gravity to separate out large solids in the sludge.
2. GN Slant Treating Equipment

gn-tank-cleaning-system-2
The after treated sludge is feed into the slant clarifier which is assembled with many pieces of stainless steel lamella plate. GN Slant Treating Equipment is especially designed to remove solids from waste slurry. Those lamella plates have the same angle of 55 degree with the horizontal line.
Water is discharged from the outlet on the upper part. While one set of screw conveyor is fixed on the triangle tank bottom, it’s used to transfer those thick particles.
GN Tank Treating Systems are easy maintenance and operating. As the main equipment in this system, GN Slant Treating is designed into a pretty compact structure which can be moved among different worksites as well.
GN Solids Control also provide dosing unit for better separation together with GN Tank System. Chemicals or flocculent can be added automatically before sending to GN treating equipment. All those flocculent systems can be put in one standard container for fast moving.
