<P>PROBLEM TO BE SOLVED: To provide a method and a device for separating H<SB POS="POST">2</SB>S that can selectively separate only H<SB POS="POST">2</SB>S from a gas to be treated containing CO<SB POS="POST">2</SB>and H<SB POS="POST">2</SB>S, and a hydrogen manufacturing system using the H<SB POS="POST">2</SB>S separating device. <P>SOLUTION: Adsorbent filling towers 11 and 21 filled with H<SB POS="POST">2</SB>S adsorbent, in which activated carbon is made to carry triethanolamine, are provided and a mixed gas derived from a synthetic gas of approximately 40°C containing CO<SB POS="POST">2</SB>and H<SB POS="POST">2</SB>S is supplied via a line 28. Valves 12 and 13 are opened, valves 22 and 23 are closed, valves 14 and 15 are closed, and valves 24 and 25 are opened. In the adsorbent filling tower 11, H<SB POS="POST">2</SB>S is adsorbed from the gas to be treated under a dry condition. In the adsorbent filling tower 21, H<SB POS="POST">2</SB>S is desorbed. When H<SB POS="POST">2</SB>S of the gas to be treated is adsorbed in the adsorbent filling tower 21 and H<SB POS="POST">2</SB>S is desorbed in the adsorbent filling tower 11, valves 12, 13, 24, and 25 are closed, and valves 22, 23, 14, and 15 are opened. <P>COPYRIGHT: (C)2013,JPO&INPIT |
