摘要： In a dehydration equipment, a regenerative gas heater heats a portion of CO2 gas dehydrated in an adsorption tower that is performing an adsorption process and supplies the gas to an adsorption tower that is performing a regeneration process. A regenerative gas preheater performs heat exchange between the CO2 gas that will be supplied to a regenerative gas heater and the CO2 gas sent out from the adsorption tower that is performing the regeneration process. Then, in the dehydration equipment, a regenerative gas cooler cools the CO2 gas that has been sent out from the adsorption tower that is performing the regeneration process and exchanged heat, separates water from the cooled CO2 gas, and returns the resulting gas to the adsorption tower. Thus, the dehydration equipment can prevent an increase in utility consumption due to the regeneration process.

摘要： A CO2 recovery system includes an absorption tower and a regeneration tower. CO2 rich solution is produced in the absorption tower by absorbing CO2 from CO2-containing gas. The CO2 rich solution is conveyed to the regeneration tower where lean solution is produced from the rich solution by removing CO2. A regeneration heater heats lean solution that accumulates near a bottom portion of the regeneration tower with saturated steam thereby producing steam condensate from the saturated steam. A steam-condensate heat exchanger heats the rich solution conveyed from the absorption tower to the regeneration tower with the steam condensate.

摘要： A CO2 recovery system includes an absorber 2 and a regenerator 3. The absorber 2 includes a CO2 absorbing section 21 and a water-washing section 22. The CO2 absorbing section 21 allows flue gas 101 to come into contact with a basic amine compound absorbent 103 so that the basic amine compound absorbent 103 absorbs CO2 in the flue gas 101. The water-washing section 22 allows the decarbonated flue gas 101A in which the amount of CO2 has been reduced in the CO2 absorbing section 21 to come into contact with circulating wash water 104 and to be washed with the wash water 104 so that the amounts of the basic amine compounds entrained in the decarbonated flue gas 101A are reduced. The regenerator 3 releases CO2 from the basic amine compound absorbent 103 the CO2 absorbed therein.

摘要： A carbon dioxide recovery unit is provided with: an absorption tower for bringing an exhaust gas into contact with a CO2 absorbing liquid to thereby absorb and recover CO2 from the exhaust gas; a regeneration tower for taking out the CO2 from the CO2 absorbing liquid; a CO2 delivery line L3 for delivering the taken-out CO2 to a storage process; and a CO2 return line L5 for returning the taken-out CO2 to the absorption tower. When a CO2 recovery unit and a CO2 compressing device are activated, if a storage process side has some kind of trouble and cannot receive the CO2, a destination part to which the CO2 is delivered from the regeneration tower is switched from the CO2 delivery line L3 to the CO2 return line L5, whereby the CO2 gas is mixed with the exhaust gas in the absorption tower.
