The invention discloses a combined absorbent for removing acid gas and application. The combined absorbent comprises cyclic substituted organic amine, a defoaming agent, a corrosion inhibitor, a deoxidant, an organic solvent and a deionized water solvent, according to the application, the combined absorbent is directly used or diluted with water and then used for removing the acid gas in the raw material gas. The combined absorbent disclosed by the invention is simple to apply, low in cost and outstanding in synergistic effect, and particularly, the energy consumption is reduced, the circulation volume of the absorbent is reduced, and the corrosion of acid gas absorption and regeneration equipment is obviously improved. 本发明公开了一种用于脱除酸性气体的组合型吸收剂及应用，该组合型吸收剂包括：环基取代的有机胺、消泡剂、缓蚀剂、除氧剂、有机溶剂和去离子水溶剂；该应用包括：将组合型吸收剂直接用于或用水稀释后用于脱除原料气中的酸性气体。本发明的组合型吸收剂的应用简单、成本低、增效效果突出，尤其是在降低能耗，减少吸收剂的循环量，酸气吸收和再生设备的腐蚀有明显改善。
