Description
吸収体温度:33℃;
再生器温度:約83℃;および
ランタイム − 約15分。
点線の吸着ユニットを用いたCO2吸着試験前(領域I/ベースライン)、その間(領域II/吸収)、およびその後(領域III/ベースラインまでの)のCO2の濃度プロファイルを図5に示す。さらに、吸着率が計算され、図6の破線で表される。
別の代表的な試験結果が図6に示され、供給ガス混合物(領域I)が13.9%であり、領域IIのCO2濃度が55%吸収されたことを示す。このプロセスを多数のサイクルにわたって連続的に運転し、35℃で吸収部にCO2が吸収されている間に、再生部サイクロン分離器で83℃でCO2の脱離が起こるようにした。ガス混合物が吸収をバイパスする領域IIIに記録されたデータから、観測されたCO2濃度は領域Iの濃度に匹敵する16%のより高い濃度に戻った。この不一致は、この一連のテストの間に不完全な流れ制御に起因すると判断された。
