るように蒸気の供給速度を切替える必要がある。(Effects) As explained above, a direct heating regeneration method using steam is used to regenerate the ion exchange resin that has adsorbed CO 2 . The regeneration process of the ion exchange resin is divided into two processes: a heating process of the ion exchange resin and a process of desorption of CO 2 from the ion exchange resin. In order to shorten the regeneration time of the ion-exchange resin, it is necessary to quickly heat the ion-exchange resin to the regeneration temperature and, after reaching the regeneration temperature, to supply the amount of heat and heat required to desorb CO 2 . Often excess steam is unnecessary. Therefore, it is necessary to switch the supply rate of steam so that a large amount of steam is supplied during the heating process of the ion exchange resin, and a small amount is supplied during the CO 2 desorption process.

Therefore, the amount of water in the metering pump 2 can be changed quickly. Note that the steam temperature is detected by the thermometer 9, and the output of the thyristor power controller 10 is thereby controlled to control the steam temperature.
