Abstract
Disclosed is a boiler may that uses recycled carbon dioxide as a working fluid. 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 a pipeline for utilization or storage. These systems will minimize heat loss and achieve essentially zero CO2 emission to the air.
Claims12
A method for heat treating hydrocarbons, comprising:
- providing a hydrocarbon fuel source mixed with an oxidant source and carbon dioxide gas to a boiler, wherein the hydrocarbon fuel source is burned in the boiler to produce a heated outlet gas comprising carbon dioxide and water;
- separating the water from the carbon dioxide in the heated outlet gas;
- and
- recycling at least a portion of the separated carbon dioxide back to the boiler.
