CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands Extraction
DownloadSpring 2020
Interfacial properties at the oil-water interface are of key importance to various operations in the petroleum industry, especially in the aqueous-based heavy oil recovery process. However, different operation stages often require different interfacial properties, which could be conflicted with...

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...
