摘要
由於國內各重化產業缺乏以吸收捕捉二氧化碳相關操作設計經驗,中鋼公司為此正建立以MEA水溶液為吸收劑之二氧化碳吸收脫附先導工場,本研究目的為替先導工場建立一整廠模擬,作為相關操作研究的依據,用以認證整體的模擬結果。
本計畫的主要研究成果為下 :
1. 完成二氧化碳先導工廠製程中吸收塔、氣提塔整廠模型的建立。
利用整廠模型完成現場數據的驗證,並可達預期去除率和去除總量的要求。
模擬以達到原設計設定的去除率95%與總捕捉量100 kg/day的標準。
2. 對二氧化碳先導工廠進行後續節能措施以及能耗評估。
目前捕捉每噸CO2所產生之CO2為203 kg,已實現CO2之淨捕捉。然而目前操作結果並未達歐盟要求的捕捉耗熱量標準3.2GJ/Ton CO2。評估目前可行節能措施有:加大熱交換器面積以增加熱回收、增加氣提塔壓力、更換溶劑。
