NOVELTY - A hydrocarbon feedstock containing stream (21) is reacted with a stream of pure oxygen to form a reaction-product stream (38) comprising carbon dioxide and water vapor. The reaction-product stream is then separated into recycle stream and intermediate product stream. The intermediate product stream is scrubbed and water vapor is condensed from intermediate product stream. The intermediate product stream is refrigerated to condense residual water and to liquefy carbon dioxide. The steam is generated from condensed water and electrolyzed to form oxygen and hydrogen gases.    USE - Process for combusting hydrocarbon feedstock stream used for hydrogen and oxygen extraction.    ADVANTAGE - The complete combustion of hydrocarbon feedstock is enabled to maximize the generation of energy and stoichiometric products. The water product generated in the reaction is subsequently electrolyzed to form recoverable oxygen and hydrogen gases. The combustion process is carried out without generation of nitrous oxides or sulfur dioxides. The flue gas generated in the process is converted to useful products and intermediates through purification process.    DETAILED DESCRIPTION - A hydrocarbon feedstock containing stream is reacted with a stream of pure oxygen in a combustion chamber (10) under conditions to form a reaction-product stream comprising carbon dioxide and water vapor. The particulate substance is removed from the reaction-product stream. The reaction-product stream is then separated into a recycle stream and an intermediate product stream. The recycle stream is sent back to the combustion chamber after passing the recycle stream through activated carbon. The intermediate product stream is scrubbed to neutralize and remove acidic impurities. The water vapor is condensed from the intermediate product stream, and intermediate product stream is refrigerated to condense the residual water and to liquefy the carbon dioxide. The steam is generated from condensed water and electrolyzed to form oxygen and hydrogen gases. The oxygen and hydrogen gases are then separated. The intermediate product stream is scrubbed with alkaline solution to form a brine solution. An INDEPENDENT CLAIM is included for system for combusting hydrocarbon feedstock streams.    DESCRIPTION OF DRAWING(S) - The drawing shows the implementations of the system and process for maximizing the generation of electrical power and marketable products from the complete combustion of various hydrocarbon feedstocks.
