PURPOSE:To treat a combustion gas efficiently by leading the combustion gas through a waste heat recovery feed-water heater, pressure-swing adsorption type water and CO2 recovery equipments, by processing regenerated gas from every recovery equipment and by sending obtained water to the feed-water heater. CONSTITUTION:A combustion gas 7 has its moisture removed by a pressure- swing type water recovery equipment 12 after passing through a waste heat recovery equipment 11 and then has its CO2 removed by a pressure-swing type CO2 recovery equipment 13. A regenerated gas from the water recovery equipment 12 is introduced into a condenser 12 to have its water removed. The condensed water is sent to the waste heat recovery feed-water heater 11 and taken out from a line 36 as a warm water. On the other hand, noncondensable gas is circulated to the combustion gas in the water recovery equipment 12. A regenerated gas from the CO2 recovery equipment 13 is sent to a CO2 condensing equipment 40 and taken out as liquefied CO2. |
