摘要： In a process for recovery of CO2 gas from a raw material mixed gas in which the CO2 is recovered by absorption followed by vacuum desorption, water in the raw material mixed gas is removed by cooling the raw material mixed gas and passing it through a rotary dehumidification apparatus having a dehumidification chamber in which water in the raw material mixed gas is removed by a desiccant, and a regeneration chamber in which water is removed from the desiccant by heating the desiccant. Unadsorbed gas discharged from the CO2 removal apparatus is heated and then used to heat the desiccant in the regeneration chamber.
