Oxy-Fuel Combustion Process

Basics

• Industrial Combustion (For heating, gassification, or other processes) that uses pure oxygen for oxidiser
• Thus nitrogen dioxides are near impossible
• Also reduces exhaust/flue gas volume
• Depending on if the fuel contains sulfur compounds or heavy metals, almost pure carbon dioxide and water vapor result
• The water can be condensed leaving near pure carbon dioxide for use in CO2 Enrichment, Industrial Use (Chemical Reactant, Woking Fluid, Carbonation etc), or for Carbon Capture and Storage workflows
• Main methods are:
  • Chemical Looping Combustion
  • Pressure Swing Absorbtion optimised for oxygen concentration (especially nitrogen removal, other gasses would mainly just lower oxygen/volume levels but not react (argon, xenon, etc)
