Seppure has developed transformative technology for separation and filtration applications in the food and pharmaceutical sectors as well as other industries. The process uses solvent-resistant nanofiltration membranes with well-defined nanosized pores to achieve chemical separations at a molecular level without the use of heat. The objective of this project is to develop and implement an industrial-scale solvent-resistant nanofiltration membrane module and system for solvent recovery and FFA removal at an oil refining facility in Alberta. The initial target market for Seppure’s technology is the canola oil processing industry in Alberta which supplies six million MT of canola oil yearly, about one-third of the total canola oil production in Canada. The technology reduces GHG emissions by reducing the energy required for industrial solvent recovery processes. The GHG reductions from this project are estimated to be 1,800 tCO2e/year, with up to 50,000 tCO2e/year upon commercialization.
