「溫室效應」為工業革命以來全球平均溫度明顯上升之主要原因之一，其中造成溫室效應原因為石化燃料大量使用使得大氣層中CO2濃度明顯增加，為了抑制CO2濃度攀升，「節能減碳」已成為國家能源環境政策發展之重點項目。為此我們於鋼鐵廠及實驗室內各建立一套CO2吸收示範設備，應用各種吸收劑作為相關研究之依據，並提供製程改善方法以達到節能效果。
本研究首先使用吸收劑23 wt% DETA + 20 wt% PZ於鋼鐵廠進行CO2吸收實驗，並針對PZ沉澱問題採取相關停機前及實驗前處理措施並找出最佳操作條件，為現階段最節能之吸收劑；而根據ASPEN模擬結果指出增加再生塔壓力可降低再生能耗，我們針對此製程改善方案以30 wt% MEA設計實驗驗證之。
我們在實驗室內架設小型固定床CO2吸收示範設備，以低濃度氨水捕獲CO2達到吸收率90 %的初步目標；並用此設備探討塔高與CO2吸收率之關係，其實驗結果與ASPEN模擬相當。
