Electrokinetic Consolidation Of Oil Sands Tailings: An Experimental And Numerical Study, Yu Guo
Electrokinetic Consolidation Of Oil Sands Tailings: An Experimental And Numerical Study, Yu Guo
Electronic Thesis and Dissertation Repository
The management of fine oil sands tailings, known as mature fine tailings (MFT), is a major challenge for the oil industry in the Northern Alberta, Canada. Dewatering and consolidation of MFT are slow and time consuming due to high water content and low permeability of MFT. The electrokinetic (EK) dewatering treatment has shown to be effective on oil sands tailings based on the results of previous researches. Therefore, this thesis is focusing on experimental and numerical studies of EK dewatering of oil sands tailings. The thesis includes three parts, i.e., EK dewatering of oil sands tailings and kaolinite slurry, EK …

Electrokinetic Dewatering Of Oil Sands Tailings, Yu Guo
Electronic Thesis and Dissertation Repository
Oil sands tailings are the final product of oil sands processing and in the form of slurry with very low solid content. After sedimentation, due to a low hydraulic conductivity of the tailings, both dewatering and consolidating the tailings are difficult. Since electrokinetic (EK) is an effective method to consolidate low permeability soils, the objective of this study is to assess the effectiveness and efficiency of EK dewatering of MFT, a man-made geomaterial. Two series of tests were conducted in this study. In the first series, four EK cell tests were performed on oil sands tailings to measure the electroosmotic …
