Pershing University of Utah Resource Extraction and Upgrading Power for CO2 capture Oil shale Oil sands Crude oil Upgrading Opportunity: Oxyfiring for CO2 capture Transportation Refining Opportunity: Improved efficiency Opportunity: Oxyfiring for CO2 capture Distribution Evaluation of Improving Process Heater Efficiency to Reduce GHG Emissions from Refineries Evaluation of Oxyfiring for CO2 Capture to Reduce GHG Emissions from Refining Well-to-Pump Life Cycle GHG Emissions from Conventional and Unconventional Transportation Fuels Case 1: A gas turbine and associated steam production provides power for the ASU and CO2 purification, compression, etc. Case 2: A gas turbine provides power to the ASU and other equipment, but steam from the turbine replaces a portion of the boiler steam. This results in a lower O2 requirement, a smaller ASU, and less cooling water. Case 3: The gas turbine is run in the precombustion decarbonisation mode with part of the oxygen being used for hydrogen production and CO2 removal using MDEA. 72 g CO2 equiv./MJ fuel
