The present invention relates to an absorbent for separating acid gas, which is excellent in terms of stripping rate and stripping amount as well as having a high level of absorption for acid gas including carbon dioxide and a high reaction rate. An absorbent for separating acid gas according to the present invention not only has a much higher acid gas absorption rate and absorption level than conventional monoethanolamine absorbents, but also has a much higher stripping rate and stripping amount, enabling the removal rate of acid gas to be enhanced under the same operating conditions, and the amount of energy required for stripping to be reduced. |
