Objective : to monitor injection parametersCO2 injection flow rate and CO2 injection flow rate and composition are measured at Lacq before transport. At early stage of the project,
CO2 injected composition was considered to be 92%
CO2, 4%O2, 3.7 % Ar, 0.3% N2

Air Boiler revamped to Oxy Boiler:
Cryogenic air separation unit240t/day oxygen required
Air Boiler revamped to Oxy Boiler:• Air Liquide has developped and built 4 oxy-burners (8MWth each)• Alstom has revamped the boiler – Major modification was the
installation of a Flue Gas Recycleinstallation of a Flue Gas Recycle• Oxy-boiler produces 40 tonnes/hour of steam 60b/450°C (30MWth)
which feeds the HP steam network of the Lacq plant
Cooling of flue gases:
30 MW/th Boiler
Cooling of flue gases:• From 250° to 30°C to condense steam and concentrate the CO2
