Oil Based Drilling Cuttings Treatment System for CNPC Project
A new set of drilling cuttings treatment plant has been ready for shipment recently. It is a waste management project for a CNPC project in China. The drilling cuttings treatment plant will be used to treat oil based mud and cuttings.
As the waste management plant will be used to treat to oil based mud and cuttings, below processing equipment are included in the quotation:
1) Vertical cuttings dryer is major equipment used to oil based mud and oil based cuttings. 1 each GNCD930D vertical cuttings dryer is included in the system. Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. GN Vertical Cuttings Dryer specially designed not only for oil based mud, SBM but also can be used for water based drilling waste.
2) Decanter centrifuge is the second stage separation equipment in the cuttings treatment plant.
3) Screw pumps are used in the drilling cuttings treatment system as flush pump for vertical cuttings dryer and centrifuge feeding pump. Many people are wondering, screw pump costs higher, why GN uses screw pump to flush the vertical cuttings dryer. Water pump price is much lower than the screw pump. Can water pump be used as flush pump for vertical cuttings dryer? The answer is No. As vertical cuttings dryer is used to treat oil based cuttings, water cannot be used for flushing. Clean oil based mud or diesel oil should be used for flush.
GN Solids Control is not only an equipment manufacturer. Another advantage of GN Solids Control is to offer complete solution. So besides the processing equipment decanter centrifuge, vertical cuttings dryer, and feeding pumps, GN Solids Control also offer the holding tank and explosion proof control system in order to offer complete solution.
Besides this set oil based cuttings treatment system, GN solids Control offered many other waste management system for CNPC project.
Hydrovac excavation waste slurry treatment system for Canada
2018 is a busy and wonderful year. Every weeks, different waste management systems or liquid / solids separation equipment are dispatched from GN Solids Control Beijing factory one by one. Recently, another full package of slurry treatment system for construction hydrovac excavation has been dispatched to sea port and will sail to Canada jobsite soon. 
The slurry treatment system will be used for hydrovac slurry separation and horizontal directional drilling slurry treatment. The principle of the slurry separation system is to use liquid and solids separation equipment to treat soil or soup or slurry generated from the hydrovac or HDD project, and produce reusable material for construction and discharge clean water.
The hydrovac excavation waste slurry treatment system for Canada client includes following packages:
1）1 set of Pick Up and Washing Tank. It is a customized V bottom tank complete with walkways, guardrails, valves, clean gate and pipelines.
2）1 set of Primary Vibration shale shaker complete with coarse Screens
3）1 set of Secondary Shale Shaker separator complete with API mesh screens
4）1 set of mud cleaner Desilter complete with shaker assembly underneath the hydra cyclone unit
5）1 set of 22 inch Big Bowl Dewatering Centrifuge with big volume for water treatment
The big bowl decanter centrifuge is located in a telescopic skid. The skid can be low down for international container shipment and for inland shipment. During working it can be lift up to suitable height.
GN Shale Shakers and desilter mud cleaner as well as the big bowl decanter centrifuge will separate soils and solids from the waste slurry water, and clarify the soil and solids into different size of particles. The recycled aggregates and soils or sands can be reused as construction field materials. The recycled water can be reused for the HDD act ivies or to be discharge.
