Abstract
A process for the efficient capture of CO2 and sulfur from combustion flue gas streams and gasification based fuel gas mixtures using regenerable and recyclable calcium based sorbents. The regeneration of the calcium sorbent is accomplished by hydrating the sorbent at high temperatures of about 600° C. and a pressure higher than 6 bars to lower the parasitic energy consumption.
