VERTI-G Cutting Dryer is a very important equipment for drilling waste management. GN Solids Control and M-I Swaco are two of the very few companies who provide VERTI-G Cuttings Dryer.
The M-I SWACO VERTI-G cuttings dryer incorporates a high-speed vertical centrifuge that achieves maximum liquid/solid separation in large-volume processing. This mechanism makes the VERTI-G Cuttings Dryer one of the industry’s best performing and most dependable cutting dryers. The VERTI-G Dryer gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings disposal.
The M-I SWACO VERTI-G Cuttings Dryer employs either auger or roto valve feed. In the VERTI-G process, cuttings are conveyed from the shakers to the dryer through a variety of site-engineered conveyance systems, including:
- Gravity feed
- Pneumatic transfer
- Vacuum transfer
- Screw conveyors
GN VERTI-G Cutting Dryer
The flow of cuttings into the VERTI-G Cutting Dryer centrifuge is PLC-controlled and continuously fed to yield optimum liquids/ solids separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the screen surface. Flights are tungsten carbide coated to reduce wear and ensure optimum tolerance.
Solids are discharged at the screen bottom and fall by gravity into the water-flushed cuttings trough and shunted overboard or collected for onshore disposal. Processed liquids pass through the screen and then exit through one of two effluent openings. The fluid is collected and pumped to the M-I SWACO decanting centrifuge for final processing and reuse in the active mud system.
In addition to helping operators around the world meet environmental demands, the VERTI-G cuttings dryer improves overall cost-efficiency. Valuable drilling fluids can be recovered from cuttings, as well as whole mud lost from shaker failure and rig motion. The VERTI-G cuttings dryer is effective with oil-, and synthetic-base drilling fluids and minimizes waste volume, dramatically reducing disposal costs
Safety Features Of MI-Swaco Vertical Cutting Dryer
- Explosion-proof motors and start/stop boxes are certified for use in Class I, Division I areas
- Integrated, custom-built stands and walkways reduce risk to personnel
GN VERTI-G Cuttings Dryer
The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation.
For the drilling waste management,GN not only have VERTI-G Cutting Dryer,but also we have HI-G Dryers available.
