Title:
CARBON DIOXIDE RECOVERING SYSTEM AND CARBON DIOXIDE RECOVERING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/095683
Kind Code:
A1
Abstract:
This carbon dioxide recovering system (1) comprises: a first adsorption tower (10) that accommodates a first adsorbent (14); and a second adsorption tower (40) that accommodates a second adsorbent (41). When the second adsorbent (41) comes into contact with a first concentrated gas supplied from the first adsorption tower (10), the second adsorbent (41) adsorbs carbon dioxide in the first concentrated gas. When heated in a second heating part (44), the second adsorbent (41) desorbs carbon dioxide adsorbed by the second adsorbent (41) and produces a second concentrated gas containing carbon dioxide desorbed from the second adsorbent (41) and having a carbon dioxide concentration higher than the first concentrated gas.
