Hebei GN Solids Control has always been leading the way in drilling waste management technology, proudly being the first solids control company
in China who developed vertical cutting dryer in 2011. With a few years’ stable and fast growing, GN has mastered the mature technology of drilling
waste management with which GN has rendered great support to Africa. Recently, 2 packages of drilling waste management system are ready for delivery to Africa.
It is completed with vertical cutting dryer, decanter centrifuge, feeding pump and screw conveyor. The equipment list is shown as below.
Two sets vertical cutting dryer are used to treat drilling waste discharged from the shale shaker, the desander and the desilter or the mud cleaner with the combination
of desander and desilter. With a high centrifugal G force produced by high speed rotating, the light liquid will be thrown through the screen, while solids will be blocked
inside the screen and be discharged out from the open space at the bottom after scraped downward by the flights. With around 4 years’ development, GN vertical cutting dryer
has been accepted by more and more big player in oil and gas field. Now GN vertical cutting dryer and complete drilling waste management system are operating in
Russia for Baker Hughes project, in China for Shell and CNPC project.
Besides 2 sets vertical cutting dryer, there are 4 set decanter centrifuges which are used to further treat the liquids discharged from the vertical cutting dryer to collect more clean drilling fluids
for recycling usage. Also there are 4 sets screw pump to feed the liquids to the decanter centrifuge, 10 sets of screw conveyor to transport the drilling waste from the shale shaker and desander&desilter
to the vertical cutting dryer .
