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 COinto the atmosphere, the bulk of the COis utilized as the working fluid and the produced COis captured and sent to the pipeline for utilization or storage. These systems will minimize heat loss and achieve essentially zero COemission to the air.
