Title:
二酸化炭素分離方法及び二酸化炭素分離装置
Document Type and Number:
Japanese Patent JP6715575
Kind Code:
B2
Abstract:
A carbon dioxide separation method including the steps of: feeding a mixed gas that contains at least carbon dioxide and water vapor to a carbon dioxide separation membrane that contains a hydrophilic resin and a carbon dioxide carrier; separating, from the mixed gas, a permeation gas that contains the carbon dioxide by use of the carbon dioxide separation membrane; adjusting temperature of gas which contacts the carbon dioxide separation membrane so that a temperature difference between the mixed gas and the permeation gas is not lower than 0°C and not higher than 20°C; and adjusting pressure of the permeation gas, the pressure of the permeation gas and water vapor partial pressure in the mixed gas satisfying the following formula (1): 2.5 kPaA < (pressure of permeation gas) < (water vapor partial pressure in mixed gas) ··· (1).
