Automatic tank cleaning system

GN automatic tank cleaning system is a set of automatic tank cleaning system designed and manufactured customized according to client’s requirement. It is a closed-loop system used for continuous cleaning of mud tanks, oil tanks, and chemical tanks.


This automatic tank cleaning system supplies clean water to the vertical pipeline pump installed next to the mud tank, and the industrial hose pump feed the sewage back to the tank cleaning system for purification. The clean water is supplied to the vertical pipeline pump for continued circulation, thereby minimizing water consumption and labor costs.
The processing capacity of this system is up to 30m3/h which can operate continuously. It consists of three parts: mud tank, walkway guardrail, manifold assembly. The inlet is equipped with GN made filter, which can effectively avoid the damage caused by large particle solids to the hose pump, thereby improving system stability and service life.
The working principal of GN automatic tank cleaning system is as below:
Firstly, the tank bottom mud is sucked by the pump through the filter by the industrial hose pump, then discharged into the inclined plate clarifier through the static mixer in the discharge manifold of the hose pump. Through the dosing pump, the chemicals are sent into the static mixer and fully mixed with the mud.
Secondly the mixed mud is settled in the inclined plate clarifier, the solid is extracted by the diaphragm pump and discharged into the skip; The liquid overflows into the mud tank from the outlet of the inclined plate clarifier, pumped out by the vertical high-pressure pump, and discharged into the automatic spraying device for cleaning. Then, it is sucked back into the purification system by the industrial hose pump for further processing.

High G Drying Shaker and Decanter Centrifuge for Oman Project

Recently one batch of high G drying shaker and decanter centrifuge are ready for shipment to Oman, including screw conveyor transfer hopper, high G drying shaker module, decanter centrifuge module. The technical configuration is as below:


1. High G drying shaker module, GNZS594J high G drying shaker installed on the mud tank, with screw conveyor transfer system to transfer the drilling cuttings automatically. Four panel composite material frame shaker screens with 2 or 3 layers of stainless steel wire mesh are installed on the shale shaker, the shaker screen is produced comply with API RP13C standard.


2. Decanter centrifuge module, GNLW363D decanter centrifuge installed on the mud tank, with screw conveyor transfer system to transfer the discharged solids to cuttings collection box automatically. Also we can provide variable frequency drive decanter centrifuge with better treatment performance.
Firstly the drilling cuttings are feeding to high G drying shaker to separate coarse solids and reduce the solids content, the fluids will drop into the mud tank under the high G drying shaker, the screw pump will feed the fluids to high speed decanter centrifuge to separate fine solids from the drilling fluids, the clean fluids will be recycled and back to solids control system to prepare for new drilling fluids, the drilling cuttings are transferred by the screw conveyor.
This system is customized designed for water based mud drilling cuttings treatment project in Oman, with electric control system and electric motor compliant with ATEX standard. For OBM and SOBM drilling cuttings treatment project, GN standard GNCM-40A drilling waste management system will be recommend, which consists of GNCD930G vertical cuttings dryer, GNLW363D decanter centrifuge with feeding pump, screw conveyor, mud tank skid and accessories.
If you need a customized solution for drilling cuttings treatment and solids control, pls contact with GN solids sales.

 

GN Desander and Desilter Centrifuge for China Drilling Company

Recently one unit of desander desilter centrifuge is ready for shipment to China drilling company.


GN Desander and Desilter Centrifuge is an efficient solids liquid separation equipment mainly used to remove solid particles such as sand and mud in drilling fluids. It is a specially designed big bowl decanter centrifuge, which separates solid particles from drilling fluid under centrifugal force through components such as a rotating bowl and a screw propeller, and discharged from solids discharge port and fluids distribution port. The Desander and Desilter Centrifuge has the advantages of wide separation particle size range, large treating capacity, compact structure, and simple operation. It can be used to replace the desander desilter mud cleaner more efficiently, with higher separation efficiency and better quality of recovered drilling fluids. The desander and desilter centrifuge has a wide range of application prospects in fields such as oil drilling, which can effectively improve the solids control quality and drilling efficiency of drilling fluids, and reduce the drilling costs.


GN decanter centrifuge applications including oil and gas drilling solids control system, drilling waste management system, oil sludge treatment plant, HDD mud recycling unit, Mining tailing slurry dewatering, TBM slurry separation, construction engineering mud treatment, mining slurry separation and other mud treatment. GN can provide CNEX, IEC EX, ATEX explosion proof motor and control panel for your option. The bowl and screw propeller rotate in the same direction with a certain differential speed, under the centrifugal force, solid phase is dropped on the bowl wall to form sediment layer, then push to the cone section and discharge through the solids discharge port.
Except for desanding desilting centrifuge, GN solids control also produce linear motion shale shaker, mud cleaner, vacuum degasser, 3 phase decanter centrifuge, vertical cuttings dryer, screw conveyor, centrifugal pump, mud agitator, mud tank system, etc solids control equipments. If you need a desanding desilting separation equipment, pls contact with GN solids sales.
