Application:
In the Alberta Oil Sands, the refining process involves recovering bitumen, a tar-like substance, through a process called Steam Assisted Gravity Drainage (SAGD). The recovered bitumen carries a substantial amount of water. Further treatment separates oils, deposits and water.
In this case the de-oiled wastewater along with raw brackish water is heated prior to a lime softener, for ultimate re-use. Higher temperature water, around 57°C was required to maximize softener efficiency, especially during cold climate conditions.
Solution:
With water flow rates up to 4200 gpm, and steam load reaching 50,000 lb/hr, a Pick Model 6X500-1FAB fabricated heater was designed, with 16” Class 150 flanged liquid connections.
Heaters run continuously for 24 hours. Maintenance has been limited to a regular 2-year PM Schedule. Nine units have been installed with the customer over a 10-year period.
