"Partial Upgrading: Challenges and Opportunities"
The extraction and upgrading of oil sands are highly energy intensive with high capital and operation costs. There have been several critical challenges that hinder further oil sands developments: 1) diluent requirement and limited pipeline capacity; 2) low raw bitumen quality, reduced value and limited access to new markets; 3) high greenhouse gas (GHG) emissions and capital/operating costs for full upgrading.
Recent studies have shown that partial upgrading technologies, especially if integrated with upstream operations can effectively overcome these challenges to reduce or even eliminate costly diluent use, increase bitumen quality and market value, and significantly reduce GHG emissions, capital and operation costs compared to bitumen full upgrading. A goal has been set by Alberta Innovate (AI) to process 20% of in-situ produced bitumen through partial upgrading by 2030. Partial upgrading is generally a relatively simple conversion process, compared to full upgrading, that partially upgrades oil sands bitumen to the level that it meets or close to meet pipeline transportation specifications in terms of density (940 kg/m3 at 15.6°C) and viscosity (350 cSt at 7°C). At the same time, other physical and chemical properties are also improved to some extent, such as total acid number (TAN) and asphaltene content, resulting in much improved bitumen quality so that refineries would be more willing to accept it as their blending refining feedstock.
This lecture will provide the audience an overview of partial upgrading fundamentals and chemistry, technology options, challenges in developing and implementing partial upgrading technologies, and research being conducted at CanmetENERGY and other research organizations.
