A PROCESS AND A PLANT FOR RECYCLING CARBON DIOXIDE EMISSIONS FROM POWER PLANTS INTO USEFUL CARBONATED SPECIES

摘要

A process is disclosed for recycling carbon dioxide emissions from a fossil-fuel power plant into useful carbonated species. Ohe process primarilycomprises the steps of: a) burning the fossil fuel, thereby generating heatand a hot exhaust gas containing CO2; and b) converting the heat into energy.The process is characterized in that it further comprises the steps of: c)cooling the exhaust gas; and d) biologically transforming the CO2 contained inthe cooled exhaust gas into carbonated species, thereby obtaining a low CO2exhaust gas and producing useful carbonated species. The low CO2 exhaust gasobtained in step d) can be released in the atmosphere without increasing theproblem of greenhouse effect.
