Sherritt Successfully Completes Pilot Testing of Innovative Process to Upgrade Alberta Bitumen at Lower Cost

TORONTO--(BUSINESS WIRE)-- Sherritt International Corporation (“Sherritt”) (TSX:S) today announced that its Alberta-based Technologies division has successfully completed a pilot-scale demonstration of a proprietary process to upgrade bitumen. The process has the ability to eliminate the need for addition of diluent, a high-cost thinning agent that reduces heavy oil viscosity, and improve pipeline capacity.

“Sherritt has identified a new application of our proven processing capabilities that addresses a significant need within Alberta’s oil sands industry to reduce costs and improve pipeline capacity,” said David Pathe, President and CEO of Sherritt International. “The successful pilot-scale demonstration marks an important first step in commercializing this technology, and builds on our unique metals processing expertise to create longer term growth opportunities. Our next testing phase is expected to involve more extensive collaboration with Alberta bitumen producers and include demonstrations of our upgrading process on a larger scale.”

Sherritt’s innovative process to upgrade bitumen is based on more than 60 years of experience developing hydrometallurgical processes and the use of autoclaves, and stems from research previously conducted by Sherritt in the area of coal liquefaction. Sherritt’s process is based on the use of reactor technology that involves combining hydrogen with bitumen under pressure at high temperature in the presence of a proprietary catalyst suspended through mechanical agitation.

Sherritt’s process was first tested in 2015 to upgrade Cuban heavy oil. More recently, Sherritt completed test work on several bitumen products from Alberta. All test work has been completed at Sherritt’s technology facility in Fort Saskatchewan, Alberta.

In recent tests, Sherritt upgraded bitumen with a 10O American Petroleum Institute (API) gravity, a unit of measurement to gauge the density of oil, to a lighter 24O API gravity product with no loss of liquid. When blended with raw bitumen, the upgraded bitumen product met pipeline transportation specifications and had lower sulphur, naphthenic acid, heavy metals and micro-carbon residue than the Alberta benchmark diluted bitumen blend, Western Canadian Select.

The addition of diluent to bitumen for transportation though pipelines is estimated to cost Alberta bitumen producers more than US$6 billion annually. Numerous studies on the partial upgrading of bitumen point to benefits such as eliminating high-cost diluent, alleviating pipeline constraints, and increasing the value of crude oil to refiners, and reducing emissions. According to the University of Calgary’s School of Public Policy, the value uplift of partial upgrading of bitumen is estimated at $10 to $15 per barrel of bitumen.
