Abstract
There is provided an acid gas absorbent having excellent performance of absorbing acid gas such as carbon dioxide, and an acid gas removal device and an acid gas removal method using the acid gas absorbent. An acid gas absorbent of an embodiment contains at least one type of tertiary amine compound represented by the following general formula (1).(In the above formula (1), the cycle A represents a cyclic structure whose carbon number is not less than 3 nor more than 8. R1, R2 and R3 each represent an alkyl group whose carbon number is 1 to 4, and R4 represents a hydroxyalkyl group. R1 and R2 are groups coupled to carbon atoms adjacent to a carbon atom forming the cycle A and coupled to a nitrogen atom.)
