Also, the preliminary cleaning water is merged with the COabsorption liquid 12, while being made to directly flow down to the COabsorbing section 13A side.
摘要翻译：要解决的问题：提供一种能够在残留在脱羧废气中时减少释放的CO吸收液的浓度的COrecovery装置和方法。解决方案：提供一种COrecovery装置，用于回收和除去含有CO的CO含量废气11A的COin CO吸收塔13使用CO吸收液12.在该装置中，CO吸收塔13包括：用于吸收CO含有废气的CO吸收部13A; 主洗涤部分13C，设置在CO吸收部分13A的气流滑流侧，并通过清洁水20在伴随排气的清洁水20中冷却CO回收液; 以及设置在CO吸收部13A和洗涤部13C之间的预备洗涤部13B。含有循环的CO吸收液的清洗水20的部分20a在主洗涤部13C中被提取，并在预备清洗部13B中预先清洗。此外，预先清洗水与CO吸收液12合并，直接向下流到CO吸收部13A侧。
