The Automated Retractable Nozzle System
Designed by John Brooks Company Limited, the Automated Retractable Nozzle System injects bitumen slurry into the TSRU (Tailing Solvent Recovery Unit) to reclaim a high proportion of the solvents. This “Hot Tap” arrangement allows a full change out of worn manifolds and nozzles while the vessel is under full load. Not only is expensive downtime eliminated, but the client can also operate efficiently with well-maintained equipment.
Since the slurry is extremely abrasive, we are providing highly wear-resistant materials. The spray nozzles are made of Tungsten Carbide, and internal pipe surfaces are overlaid with Chromium Carbide. The extraction cylinder is chrome plated to prove a smooth extraction of the worn parts and a tight seal.
John Brooks has one of the most experienced engineering groups for Oil Sands Automatic Retractable Nozzle Systems. Our field engineers coordinate the client requirements with our design department to ensure a cost-effective and reliable solution.
Features:
- CFD analysis to determine optimal nozzle type and location in the vessel for efficient solvent recovery and to minimize wall wetting.
- Hollow Cone, Full Cone or Flat Spray Nozzles in Tungsten Carbide for exceptional service life.
- Manifolds designed for ideal delivery of slurry within the vessel.
- Chrome Carbide overlay on the internal pipe and wetted surfaces.
- The OD of the extraction cylinder is chrome plated for corrosion protection and seal integrity.
- Packing box designed, manufactured and tested to ensure compliance with fugitive emissions standards.
- Motor-operated linear drive assembly on the extraction mechanism.
