THREE-COMPONENT ABSORBENT SOLUTION AND DEVICE AND METHOD FOR REMOVING CO2 AND/OR H2S |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a three-component absorbent solution having not only absorbing capacity but also regeneration capacity and a device and method for removing CO<SB POS="POST">2</SB>and/or H<SB POS="POST">2</SB>S. <P>SOLUTION: (1) A first amine which is a straight-chain secondary monoamine, (2) a second amine which is a cyclic secondary polyamine serving as a reaction accelerator and (3) a third amine consisting of one type selected from a secondary or tertiary cyclic amine group or a straight-chain amine group with a high steric hinderance are combined to obtain an absorbent solution. By way of the synergistic effect of these components, excellent absorption of CO<SB POS="POST">2</SB>and/or H<SB POS="POST">2</SB>S and excellent dissipation of the CO<SB POS="POST">2</SB>and/or H<SB POS="POST">2</SB>S absorbed during regeneration of the absorbent solution can be exhibited, and the amount of water vapor used in CO<SB POS="POST">2</SB>capturing equipment during regeneration of the absorbent solution can be reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
