Synergistic Role of Sodium Hydroxide and Sodium Citrate on Bitumen Slime Coating in Process Water
DownloadFall 2021
Sodium hydroxide (NaOH) is generally used as the primary processing aid in the water-based oil sands extraction for the recovery of bitumen. It was found by Syncrude Canada Ltd. that the combined use of sodium hydroxide and sodium citrate could effectively improve the bitumen recovery as compared...

Understanding the Role of Caustic Addition: A Comparison of Sodium Hydroxide and Ammonium Hydroxide
DownloadSpring 2012
To understand the role of caustic addition and its effect on the bitumen extraction process, a novel flow cell and a Denver Cell extraction unit were utilized. This allowed for the comparison of sodium hydroxide and ammonium hydroxides effect on real oil sands ores. Several ores (A1, C-ore,...
