工業化社會使得經濟快速成長,然而快速發展與高度開發,同時使得我們生活環境陷入加速惡化的困境,近年來,溫室效應問題尤其嚴重,二氧化碳減量已成全球趨勢。化學吸收法為常見的二氧化碳捕集方法,為降低捕集設備成本,具高質傳特性的旋轉床技術被提出,本研究以Kang et al (2014)建立之g-Proms旋轉床與固定床反應器模型分別模擬在不同氣液進量比、不同氣相線性流速以及內徑、外徑、高之幾何條件限制下達90%二氧化碳移除率所需之旋轉床與固定床體積,並進行比較,以期可以降低反應器設備規模。依據模擬結果,旋轉床反應器體積與固定床反應器體積比較之優劣決定於氣相線性流速以及幾何設計之高寬比,此外,吸收劑之負荷亦會影響旋轉床之效率,其不適用於高負荷溶液條件,故目前在最低能耗吸收劑條件下,尚無法以一個旋轉床反應器取代傳統固定床反應器,但是旋轉床反應器之反應效果可以再透過調整氣液流量比、轉速等加以善,未來持續研究新的方法使旋轉床反應器整合至傳統二氧化碳吸收製程中使用
