二氧化碳的排放造成全球氣候變遷，是近年來世界各國所重視的課題。未來除了提高能源使用效率外，捕捉二氧化碳之回收，可減少大氣中二氧化碳的濃度；而在吸收之基礎研究及製程開發上已經有不少論文發表於國際期刊中，為此我們在一鋼鐵廠建立一個吸收脫附實驗工場，以不同的吸收劑作為相關操作研究的依據，並提供幾種方法來達到節能的結果。
本論文的主要研究成果為下列 :
1.製程之最佳化操作模擬評估與最佳化操作條件現場測試
模擬以MEA水溶液為吸收劑，達到去除率90%以上及100kg CO2/day的標準，再配合現場數據進行比較。
2.更換吸收劑於現場操作實驗
更換新型溶劑AMP+PZ與DETA+PZ，在線上工場進行實驗並計算其能耗，在與MEA溶劑去比較能耗可以降低多少。
3.綜合設備及製程改善方案
現階段能耗約在5.6GJ/ton CO2，但操作結果並未達到歐盟要求的捕捉能耗標準3.2GJ/Ton CO2;若需降至歐盟標準，評估可行方法為:加大熱交換面積以增加熱回收、增加氣提塔壓力、更換新型溶劑或使用濃度較高的溶劑。改善方案中模擬熱回收與增加氣提塔壓力，來評估可降低多少能耗。
