Publication number: 20200157432Abstract: A process for dewatering oil sand fine tailings is provided and comprises a dispersion and floc build-up stage comprising in-line addition of a flocculent solution comprising an effective amount of flocculation reagent into a flow of the oil sand fine tailings; a gel stage wherein flocculated oil sand fine tailings is transported in-line and subjected to shear conditioning; a floc breakdown and water release stage wherein the flocculated oil sand fine tailings releases water and decreases in yield shear stress, while avoiding an oversheared zone; depositing the flocculated oil sand fine tailings onto a deposition area to form a deposit and to enable the release water to flow away from the deposit, preferably done in a pipeline reactor and managing shear according to yield stress and CST information and achieves enhanced dewatering.Type: ApplicationFiled: January 25, 2020Publication date: May 21, 2020Inventors: Adrian Peter Revington, Oladipo Omotoso, Patrick Sean Wells, Thomas Charles Hann, Marvin Harvey Weiss, Trevor Bugg, Jamie Eastwood, Stephen Joseph Young, Hugues Robert O'Neill, Ana Cristina Sanchez

Patent number: 9068776Abstract: Methods for drying oil sand fine tailings treated to comprise flocculated fine tailings, by deposition and farming techniques, are provided. A deposition cell is provided with a sloped bottom surface and the flocculated fine tailings are deposited to undergo channelless advancement in the cell while allowing drainage of release water. When the deposit is uneven, the deposit may be plowed while wet for spreading and ensuring water release conditioning is imparted thereto, while avoiding over-shearing, and maintaining sufficient shear strength to allow standing. Once a dried upper crust forms, the deposit may be harrowed to break up the crust, expose wet regions there-beneath and create furrows in the standing deposit. The methods improve the dewatering and drying of mature fine tailings in oil sands.Type: GrantFiled: October 30, 2009Date of Patent: June 30, 2015Assignee: SUNCOR ENERGY INC.Inventors: Trevor Bugg, Jamie Eastwood, Adrian Peter Revington, Marvin Harvey Weiss, Patrick Sean Wells, Thomas Charles Hann, Stephen Joseph Young, Hugues Robert O'Neill

Patent number: 7606221Abstract: A telephony communications approach implements an autodiscover feature that enables an endpoint device to automatically locate and establish communication with a desirable server in a web of interconnected servers. In one specific example implementation, the endpoint device is an internet-type telephone communicating with a remotely-located server in an internet-based private branch exchange. Various packet-communicating endpoint devices are adapted to communicate with the internet-based private branch exchange by adapting each to automatically broadcast its identity and, in response to receiving an assignment for the appropriated iPBX, establish communication with the internet-based private branch exchange from other packet-based servers. Other aspects of the invention are directed to approaches for distinguishing the desired internet-based private branch exchange from the other packet-based servers and implementations for assigning the appropriate iPBX.Type: GrantFiled: November 24, 2004Date of Patent: October 20, 2009Assignee: 8×8, Inc.Inventors: Fredric Artru, Andy Huckridge, Marc Petit-Hugenin, Jean-Hugues Robert, Michael Roper, Philip Bednarz
