First, a raw material mixed gas is introduced from the introduction part 11, and steam is passed through the steam tube (heat exchanger) 13 to heat the mixed gas. The pressure of the supplied mixed gas in this case is not particularly limited and is appropriately selected depending on the structure of the hollow fiber 24, etc., but if the pressure at the time of discharging the permeated gas is near atmospheric pressure, it should be approximately 2 kg/cm 2 or more.
