In an air humidity regulating method for gas subjected to treatment, a first medium (22) is Il caused to flow onto a heat exchanging pipe (17) of a gas-liquid contact part (18) in a dehumidifier (11); meanwhile, a second medium M Ge (24) is passed through the heat exchanging pipe (17). In this state, air is fed into a gas-liquid contact case (13) from an inlet port (14) and gas-liquid contact is made by the first medium (22) on the gas-liquid contact part (18) so as to absorb water content from the air into 0 ----, the first medium (22). The first medium (22) contains an ionic liquid having high absorbency. The temperature of the first medium (22) Il is regulated by the second medium (24). After that, treated air is discharged from an outlet port (15) of the gas-liquid contact case (13). 0 NI 0 [Continued on next page] WO 2019/068315 Al I0111I0III11II111111011101110111IIII1001 VIII VIII VIII OM II ill 1114110111111111111 (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
