  • Patent number: 9505998
    Abstract: A method and system for processing an input fuel gas and steam to produce separate CO2 and output fuel gas streams. The method comprises the steps of using a decarbonizer segment for reacting at least a solid sorbent with the fuel gas and steam to remove carbon from the input fuel gas and to produce the output fuel gas stream in an exhaust gas from the decarbonizer; using a calciner segment for reacting the solid sorbent from the decarbonizer segment therein to release the CO2 into the CO2 gas stream; wherein CO2 partial pressures and temperatures in the decarbonizer and calciner segments respectively are controlled such that the temperature in the decarbonizer segment is higher than the temperature in the calciner.

  • Patent number: 8894743
    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.

  • Patent number: 8632626
    Abstract: A system and System for removing CO2 from an input gas stream. The system comprises a carboniser segment configured such that a solid sorbent reacts therein with the input gas stream to remove CO2 from the input gas stream; a calciner segment configured such that the solid sorbent from the carboniser segment reacts therein to release the CO2 into a substantially pure gas stream; a heat exchanger unit for exchanging heat between the carboniser and calciner segments; a first conditioning unit for controlling a CO2 partial pressure in the carboniser segment; and a second conditioning unit for controlling a CO2 partial pressure in the calciner segment; wherein the first and second conditioning units are configured such that a difference between the CO2 partial pressures in the carboniser and calciner segments respectively is controlled such that heat is provided from the carboniser to the calciner through the heat exchanging unit.
