Abstract:
A process for the production of electric energy, steam, and carbon dioxide in concentrated form from a hydrocarbon feedstock, said process comprising:forming synthesis gas in an air driven autothermal thermal reactor unit; heat exchanging the synthesis gas for the production of steam; treating at least a portion of the synthesis gas in a shift convertor unit, a carbon dioxide absorber, and a desorber to form concentrated carbon dioxide and a lean hydrogen containing gas from the carbon dioxide absorber; combusting at least a portion of the of the lean hydrogen containing gas in a combined gas cycle turbine for the production of electric energy; supplying air from the combined gas cycle turbine to the air driven autothermal thermal reactor unit; heat exchanging exhaust from the combined gas cycle turbine for the production of additional steam; and supplying the steam and the additional steam to a power generator for the production of substantially CO2-free electrical energy.
