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.
