The Effect of Freezing and Thawing on the Dewatering of Oil Sands Sludge. IN: Proceedings of the Conference Reclamation, A Global PerspectiveDownload
Oil sands processing operations in northeastern Alberta generate 25 x 106 m3 of water-fines mixtures (sludge) per year. The fines settle in several weeks but will not consolidate to more than 35% solids, even over centuries. Freezing and thawing the oil sands sludge led to rapid dewatering. ...
This report is a condensed version of two reports on the chemistry of a variety of oil sands substrates from Syncrude, Suncor, OSLO and SolvEx. The study was conducted by EnviroTest Laboratories for RRTAC, Syncrude, Suncor and OSLO. Page 2 of the report identifies the source of the various...
