Abstract
A method of removing CO2 from an input gas stream, the method comprising reacting a solid sorbent with the input gas stream to remove CO2 from the input gas stream in a carboniser; reacting the solid sorbent from the carboniser in a calciner to release the CO2 into a substantially pure gas stream; exchanging heat between the carboniser and calciner; and controlling a CO2 partial pressure and temperature in the carboniser and a CO2 partial pressure and temperature in the calciner such that the temperature in the carboniser is higher than the temperature in the calciner for providing heat from the carboniser to the calciner.
