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.
