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
• Outside of cases where the flue contains sulfur compounds or heavy metals, the flue gas is almost pure carbon dioxide and water vapor
• 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:
  • Replacing the "Air in" in a burner/combustor with (sometimes dilluted) oxygen
  • Chemical Looping Combustion
