Reference number : GC-2017-Q4-01110, amendment number : , agreement type : G, recipient legal name : Lu, Qingye (University of Calgary), recipient country : CA, recipient province : nan, recipient city : Alberta, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Suncor uses both surface mining and steam-assisted gravity drainage (SAGD) to recover bitumen. In SAGD_x000D_
operations, almost all the steam injected is recovered as produced water at the surface. It is highly desirable to_x000D_
recycle the maximum possible amount of water of SAGD process to reduce operational costs and overall water_x000D_
consumption. The percentage of produced water recycled depends on the performance of the chemical_x000D_
treatment process consisting of a warm lime softening unit, an After Filter, and a weak acid cation exchange_x000D_
unit. The chemical treatment of SAGD produced water is a complicated process with a lot of factors_x000D_
influencing its performance. A wide range of colloid and interface science related phenomena are involved in_x000D_
SAGD produced water chemical treatment and need to be fundamentally understood. The basic understanding_x000D_
of these phenomena will lead to improved practice of SAGD produced water treatment. A series of jar tests_x000D_
will be carried out in synthetic waters to evaluate the impact of chemicals including type and dosage on the_x000D_
coagulation of CaCO3 and Mg(OH)2 particles as well as total suspended solids (TSS) and total organic carbon_x000D_
(TOC) removal. By comparing the water characterization data of the synthetic waters before and after_x000D_
treatment, correlations will be constructed to correlate the performance of CaCO3 and Mg(OH)2 coagulation_x000D_
and TSS/TOC removal to chemicals species and dosage. The information obtained will be used to elucidate the_x000D_
coagulation and removal mechanisms. Basic questions like how coagulant interacts with the feed TSS/TOC of_x000D_
the synthetic waters as well as formed CaCO3 and Mg(OH)2 particles will be answered., program purpose french : Suncor uses both surface mining and steam-assisted gravity drainage (SAGD) to recover bitumen. In SAGD_x000D_
