Since GN’s establishment from 2006, its solid control equipment and mud recycling system have been sold to more than 60 countries. GN’s mud recycling system can be applied in many areas, such as oil and gas drilling, diamond drilling, HDD, tunnel boring, piling, dredging, etc. Today we will discuss one application of the mud recycling system based on one case study: the project in London.
Just several months ago, GN Solids Control sold one set of mud recycling system to a UK customer for civil works. This system consists of a double deck shale shaker and a decanter centrifuge. The shale shaker is used for coarse separation to eliminate the large size solids. The screens on the upper deck will have smaller API number than the lower deck, which means the lower deck screen could separate finer solids than the upper deck screen. Then the processed fluids will drop to the tank and then pumped by a screw pump to the decanter centrifuge for further separation. The decanter centrifuge can separate the solid size up to 20 microns. The centrifuge is built tough and need less maintenance during normal operation. The bowl is made of duplex casting 2205 stainless steel, the bearing is made by world famous SKF, the screw conveyor and discharge port are protected by tungsten carbide tiles. There is also tough cover the spring to protect the decanter centrifuge during transportation. And after this separation, the mud could go back to the system to be reused again. This will be very environmental and cost effective. GN can customize the mud recycling system according to customer’s different requirement and give customer the best solution.
