GN Vertical Cuttings Dryer is used in the drilling industry for recovery oil from the drilling cuttings.In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed.GN drilling cuttings dryer system consisting of Vertical cuttings Dryer and the relevant equipment could discharge 1 barrel of liquid for 4 barrels of solids removed.GNCD930 vertical cuttings dryer has proven to reduce this liquid to below 5% (OOC) by weight by site test：
Reduce the amount of OBM or SBM on cuttings discharge to reduce waste volume and meet environmental objectives.
Recover valuable base fluids for reuse and lower the cost.
Reduce fluid content prior to other treatment, thereby increasing process capacity.
In short, GNCD930 Vertical Cuttings Dryer could help you meet environmental objectives by reducing waste volume, maximizing liquid recovery and reducing your project cost.GN Solids Control can provide all-around mud recycling and treatment equipment.
Features and Benefits for GN Vertical Cuttings Dryer
The flights are made from hard high chrome alloy material to be anti-abrasive from solids and ensure long operational life vertical cuttings dryer.
Air Knife is Provided for cleaning the screen to avoid screen blinding.
Balance testing for all major rotary components to minimize vibration & noisy
Individual oil lubrication system with automatic alarm for pressure limit.
Screw conveyor installed under the dryer to pick up the dry solids for continues operation.
Cleaning pump provided for avoiding solids accumulation in the cuttings dryer
GNCD930 cuttings dryer is a single stage continuous phase vertical screen centrifuge that has proven to reduce the oil on cuttings to as low as 5% by dry weight and typically achieves below 5% OOC levels. GNCD930 Vertical cuttings dryer is capable of processing over 40-50 tons per hour and can deliver dry solids under the most severe loading. GNCD930Cuttings Dryer has been used on many types of fluids, including drilling fluids of both synthetic and oil based mud. As with all solid control equipment, like shakers, centrifuges and cyclone separator, viscosity will have an impact on performance. Viscosity is determined by many factors including solids content, solids size, fluid type and fluid temperature.
In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed.GN drilling cuttings dryer system could discharge 1 barrel of liquid for 4 barrels of solids removed. This recovery is measured after processing through the solid bowl decanting centrifuge.
The drilling fluid from vertical cuttings dryer contains a percentage of low gravity fine solids that should be treated by a high speed centrifuge before the mud can be returned to the active system. This may not be necessary in all conditions. The cuttings dryer screen bowl is available with different mesh openings.
Other than the vertical cuttings dryer itself, other equipment could include a support stand and a high-speed centrifuge with feed pump and stand. Additional equipment may include the feed system, whether auger, vacuum transfer system, or positive displacement feed pump package.
Installation time varies greatly with conditions and is dependent on many things, most importantly a proper survey prior to installation. Installation time is achievable within 2 or 3 days if no hot work is needed.
