Osum Oil Sands Corp. will use water treatment technologies from Veolia Water Solutions & Technologies to process produced water from its Taiga Project at Cold Lake in Alberta. Osum will produce bitumen utilising the in situ steam assisted gravity drainage (SAGD) process beginning production in 2013.
This produced water treatment system consists of AutoFlot® induced gas flotation and Power Clean® oil removal filter technologies for the secondary deoiling process. HPD evaporators will then process the deoiled produced water to provide high quality water to the once through steam generators as well as treat the resulting blowdown.
The produced water treatment system is an example of the adoption of technologies and directives by Osum to minimise the impact of the Taiga project on the surrounding environment. The evaporator system will recover over 93% of the water from SAGD operations for reuse in the process. More importantly, Osum will use no freshwater in the extraction process; instead using high salinity water for makeup demand for steam generation. The Silica Sorption™ process used in the evaporator package was designed to tolerate the use of this brackish water as makeup that is unfit for consumption.
Flexible disposal of the evaporator concentrate from the Silica Sorption process allows minimal treatment and safe handling of waste prior to disposal. Osum plans to use onsite disposal facilities for this concentrate in an effort to reduce truck traffic in the area.
Osum is a privately held Alberta based company focused on the application of environmentally responsible in situ recovery technologies within Canada’s oilsands and carbonates.
