Fixed or VFD APVCD Series Vertical Cuttings Dryer Is Also Referred To Centrifuge Separator

Vertical cuttings dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids, which is used to process the oil base fluids drilled cuttings and the oil mud waste. The main principle of it is centrifugal force separation. Almost oil bas mud waste will use cuttings dryer to help get more dry disposal from the management system

Applications

Offshore and onshore projects where the recovery of valuable drilling fluid from cuttings, as well as recovery of whole mud lost from shaker failure, rig motion and screen blinding are priorities.

Problems

More stringent cuttings-discharge regulations have pressured operators and drilling contractors to reduce drilling wastevolumes and recover premium products for reuse.

Solutions

The vertical cuttings dryer features a state-of-the-art design that can process varying amounts of cuttings and fluids, typically up to 60 tons per hour. Dry solids discharged from the dryer are typically≤5% oil content by wet weight.

Economics

The vertical cuttings dryer improves overall cost-efficiency, producing reduced amounts of extremely dry cuttings for disposal and recovering valuable fluid for reuse. It is effective with water-, oil- and synthetic-base drilling fluids.

More details of vertical cutting dryer

Vertical cuttings dryer holding high efficiency separation on drilling fluid and it will minimize drilling cuttings content in drilling fluids. The cuttings dryer decrease disposal percentage benefit much on “0” disposal application. Separate drilling mud recycling by solids control system effectively. Recycle the lost mud caused by equipment failure, etc. The common spare parts are easy to be replaced. The wolfram carbide alloy knives on cones are changeable also minimize the whole device failure.

The Vertical Cuttings 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 with G force to 420G.

Liquid is forced to pass 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.
