摘要翻译：要解决的问题：提供一种CO 2 恢复装置和CO 2 恢复方法，其可以进一步减少胺化合物的浓度保持在脱碳废气中并排出。解决方案：在CO 2 恢复装置中，使含CO 2 的废气11A与 CO 2 吸收液体12以消除CO 2 ，以在吸收塔13处形成净化废气11B，CO 2 与CO 2 吸收液分离，以回收CO 2 吸收在吸收液体再生塔14中的液体12和在吸收液体再生塔14中消除了CO 2 的贫溶液12B在CO 2 吸收塔13. CO 2 恢复装置设有冷却塔70，冷却塔70将CO 含有CO 2 的排放气体，设置在CO 2 吸收塔13的上游。（T 2 ）排出吸收塔被设置为较低（T 1 > T 2 SB> =含有CO 2 的含有CO 1 ） POST“> 2 并在冷却塔处冷却; 并且在蒸发器90中蒸发从吸收液体再生塔14排出的冷凝水蒸气产生的冷凝水44。（C）2013，JPO＆INPIT
