studying atmospheric drying of oil sands tailings
Barr is working with oil-sands clients in western Canada on ways to use atmospheric drying to strengthen fine tailings for reclamation and to reduce air emissions. Tailings are the sediments remaining after crude bitumen is removed, and oil sands mining generates a significant quantity of these. The strengthening process has been likened to turning something the consistency of yogurt into something strong enough to plant a forest on.
Our work has included evaluating dewatering rates and strength gain for atmospheric-drying test methods and comparing the resulting emissions to those from traditional tailings-pond operations. Using this data, we’ve assessed the effectiveness of atmospheric drying and modeled emissions-generation rates and dispersion. We recently presented our findings at an international oil sands conference.
