Description
こうして製造されるガス中には、水素と共に多量のCO2も含まれているため、水素の工業的利用にはCO2の除去・回収が必要である。
(CO2/水素分離)
本発明のシステムを用いて、水素からCO2分離回収を行った。
・供給ガス組成:CO2(50%)/水素(50%)
・供給ガス全圧(絶対圧):4atm
・供給ガス露点:−20oC以下
・供給ガス流速:600mL(STP)/min
・透過側全圧:大気圧
・有効膜面積:10cm2
なお、本実施例では、脱水工程後を想定した模擬ガスを用いることとした。
供給ガス全圧:絶対圧0.4MPa、供給ガス全流量600mL(STP)/minとして、上記と同様にしてCO2の分離回収を行った。
供給ガス全圧:絶対圧0.4MPa、供給ガス全流量300mL(STP)/minとして上記と同様にしてCO2の分離回収を行った。
