Carbon dioxide absorbent comprising amino acid and tertiary alkanolamine, method for capturing carbon dioxide using the same, and apparatus for capturing carbon dioxide using the same

摘要

The present invention relates to a novel carbon dioxide absorbent comprising an amino acid and a tertiary alkanolamine, and a carbon dioxide absorbing method and a collecting apparatus using the carbon dioxide absorbing agent. And non-toxic, does not react with oxygen to generate heat, and has a low recovery energy compared to alkanolamine-based absorbents, and does not form salt precipitates upon absorption of carbon dioxide, The present invention can be applied to an absorption tower in the form of a packing tower as well as an absorption tower, which is very effective for improving the absorption efficiency of carbon dioxide.
