Publication number: 20220055083Abstract: A process for the treatment of thick fine tailings that include constituents of concern (CoCs) and suspended solids is provided. The process includes subjecting the thick fine tailings to treatments including chemical immobilization of the CoCs, polymer flocculation of the suspended solids, and dewatering. The chemical immobilization can include the addition of compounds enabling the insolubilization of the CoCs. Subjecting the thick fine tailings to chemical immobilization and polymer flocculation can facilitate production of a reclamation-ready material, which can enable disposing of the material as part of a permanent aquatic storage structure (PASS).Type: ApplicationFiled: September 7, 2021Publication date: February 24, 2022Inventors: Oladipo OMOTOSO, Adrian REVINGTON, Marc GORANSON, Patrick Sean WELLS, Macoura KONE, Daryl HOCKLEY, Baha Elsayed ABULNAGA, John DIEP, Benito MOYLS, Alan MELANSON, Rodney GUEST, Naveen PRATHAP, Babak DERAKHSHANDEH

Publication number: 20210102125Abstract: Techniques for dewatering thick fine tailings may include flocculant dosing on a clay basis and then subjecting the flocculated tailings to dewatering, for instance by pipelining the flocculated material from flocculant addition to a deposition site. The thick fine tailings can be pre-treated by removing hydrocarbons and shear-thinning prior to flocculant addition.Type: ApplicationFiled: December 17, 2020Publication date: April 8, 2021Inventors: Adrian Peter Revington, Ana Cristina Sanchez, Trevor Bugg, Oladipo Omotoso

Patent number: 10899969Abstract: Techniques for dewatering thick fine tailings may include one or more pre-treatment steps, such as pre-shearing to reduce the yield stress prior to flocculation, hydrocarbon removal below a threshold to improve flocculation and dewatering, flocculant dosing on a clay basis, and providing certain properties of the thick fine tailings related to coarse and fine particle sizes and/or chemistry such as divalent cation content. Various advantages may result from pre-treatments based on thick fine tailings properties, such as reduced flocculant dosage requirements, improved dispersion of flocculant into the thick fine tailings and/or enhanced dewatering, for example. One or more of the pre-treatments may be performed.Type: GrantFiled: June 21, 2013Date of Patent: January 26, 2021Assignee: SUNCOR ENERGY INC.Inventors: Adrian Revington, Ana Sanchez, Trevor Bugg, Oladipo Omotoso
