The VERTI-G cuttings dryer incorporates a high-speed vertical centrifuge that maximizes liquid-solid separation in large-volume processing. This mechanism makes the VERTI-G dryer one of the industry’s best performing and most dependable cutting dryers. Available in both standard and compact configurations, the VERTI-G dryer gives operators a critical advantage in meeting increasingly stringent environmental regulations for offshore cuttings disposal.

Versatility and high performance

Drill cuttings are conveyed from the shakers to the VERTI-G cuttings dryer through a variety of site-engineered conveyance systems, including

• gravity feed
• pneumatic transfer via CLEANCUT cuttings collection and transportation system
• vacuum transfer
• screw conveyors.

Maintained by programmable logic control (PLC), the flow of cuttings into the VERTI-G dryer is continuously fed to optimize liquid-solids separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the screen surface. The flights are coated with tungsten carbide to reduce wear and ensure increased tolerance.

Flights within the VERTI-G dryer create a rolling action that promotes efficient separation and prevents screen plugging. Under high G forces created by the large cone diameter, liquid-solids separation occurs instantly as cuttings make contact with the finer-mesh, high-capacity centrifuge screen. The result is clean return fluid and dry solids discharge.
