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:

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.
