Vertical Cuttings Dryer
The vertical cuttings dryer is aimed to reduce the liquid content of drill cuttings which is safe to discharge to the environment or as preparation for bio-remediation. The typical discharge criteria is expressed as Oil on Cuttings (OOC) or Retained Oil on Cuttings (ROC). The criteria may be set at a local/national level by economical or legislative requirements.
The cuttings dryer can also capture and return valuable drilling fluids from the mud losses of the shakers. The returned fluids can be pumped back to the active mud system.
For Drill Cuttings Treatment Applications
Screw conveyors collect the drill cuttings from primary solids control equipment of drilling rig and feed into vertical cuttings dryer. The solids discharge to a collection box for further process, while the liquid flows to a high speed decanter centrifuge to recycle valuable fluid and transfer back to the active mud system.
