Carbon Dioxide

REI has developed expertise in CO2 Control technologies, particularly oxy-combustion. In oxy-combustion, fuel is burned with a combination of pure oxygen and recycled flue gas instead of air. This provides a high quality CO2 stream that would be ready for sequestration or use in enhanced oil recovery activities. REI has extensively studied retrofitting a typical coal-fired boiler for oxy-combustion. The different combustion environment present during oxy-combustion leads to difference in gas volumes, gas heat capacities, flame ignition, radiative heat transfer, particle and acid gas clean up requirements, and potential deposition and fouling issues.
