    • PROBLEM TO BE SOLVED: To provide a CO 2 recovery process decreasing the cooling capability of a refrigerator and the power of a compressor and capable of recovering and liquefying CO 2 generated in the process. SOLUTION: The CO 2 recovery process comprises: previously separating a mixed gas into hydrogen and a CO 2 concentrated gas; then feeding the CO 2 concentrated gas to a heat exchanger; thereafter cooling the CO 2 concentrated gas in a cooling device, a multiple heat exchanger and a refrigerator in order; separating the cooled CO 2 concentrated gas into a liquefied CO 2 and a non-condensed gas in a liquid/gas separating tank; raising the pressure of the liquefied CO 2 by a liquid pump and transporting the liquefied CO 2 to the multiple heat exchanger; and subjecting the non-condensed gas to heat exchange with the CO 2 concentrated gas by the multiple heat exchanger and the heat exchanger. In the CO 2 recovery process, the cooling capability of the refrigerator and the power of the compressor can be decreased and CO 2 generated in the process can be recovered and liquefied.

    • PROBLEM TO BE SOLVED: To obtain a thermoelectric hydrogen supply system including a cogeneration system (CGS) using LNG, and a hydrogen separation type steam reformer. SOLUTION: The thermoelectric hydrogen supply system supplying heat, electricity and hydrogen includes: the CGS in which natural gas obtained by vaporizing the LNG is used as fuel; the hydrogen separation type steam reformer performing steam reforming of the natural gas; and a combustor as a heat source for steam reforming. (a) The exhaust gas from the CGS and the off gas from the hydrogen separation type steam reformer are joined together; (b) the thermoelectric hydrogen supply system includes a carbon dioxide recovery device including a compressor, a cooling heat exchanger and a gas-liquid separation vessel arranged sequentially when the exhaust gas and the off gas are viewed in the flow direction thereof; (c) the LNG is used as cool of the cooling heat exchanger; (d) oxygen-rich air is used in the CGS and the combustor as the heat source for steam reforming; and (e) the steam generated by the CGS is used in the steam reformer.
