A system and a process for combusting hydrocarbons to recover energy and the carbon dioxide resulting from the combustion is provided. The process utilizes a two-stage combustion process, each stage utilizing water injection and a recirculation stream to increase the efficiency of combustion to generate larger proportions of carbon dioxide. An energy recovery boiler is used to recover heat energy from the combustion product. Combustion product is then cleaned and the carbon dioxide is separated and condensed into a useable liquid carbon dioxide product.

[ I claim:] [1.] A process for combusting hydrocarbon streams and recovering the carbon dioxide produced during combustion, the process comprising the steps of:reacting a first hydrocarbon containing stream with a second stream of substantially pure oxygen in a combustion chamber under conditions producing a reaction product stream comprising carbon dioxide and water vapor;removing particulate matter from the reaction product stream;separating the reaction product stream into a recycle stream and an intermediate product streamrecycling the recycle stream into the combustion chamber;subjecting the intermediate product stream to electron beam oxidation to breakdown residual organic compounds and to electrostatically charge residual particulate matter;removing the electrostatically charged particulate matter from the intermediate product stream;scrubbing the intermediate product stream to neutralize and remove acidic impurities;condensing water vapor from the intermediate product stream; andrefrigerating the intermediate product stream to condense any remaining water and to liquefy the carbon dioxide.
