  • Oxy-fuel cracking furnaces and boilers using CO2 as the working fluid
    Patent number: 11370725
    Abstract: Disclosed is an ethylene and/or propylene cracker unit that uses recycled carbon dioxide as a working fluid. A boiler may also use recycled carbon dioxide as a working fluid. In either instance, instead of releasing high-purity CO2 into the atmosphere, the bulk of the CO2 is utilized as the working fluid and the produced CO2 is captured and sent to the pipeline for utilization or storage. These systems will minimize heat loss and achieve essentially zero CO2 emission to the air.
    Type: Grant
