Description
本発明は、気液接触又は気液反応を含む多くの用途に好適であり得る、気体と液体とを接触させるためのシステムに関する。
気液接触装置(Gas-liquid contactors)は、多くの産業、例えば化学、生化学、石油化学及び冶金学産業等において広く用いられる。これらの接触装置又はリアクターの選択、設計、サイジング及び性能は、しばしば、質量及び熱伝達、流体力学、及び反応速度論に依存する。これらのユニットは、通気装置又は気液リアクターとして一般的には見かけられ、気体が最初に液体に溶解し、次いで液体又は液体に溶解された任意の材料と反応する。そのようなリアクター中における反応は、しばしば、低速及び高速レジームに分類される (Advances in Chemical Engineering, Academic Press 1981, pp. 1-133)。低速反応のためには、バルク中における気体濃度を飽和近くに維持するために、高い液体滞留と物質移動が必要である一方で、高速反応のためには、液体バルク中における気体濃度が殆どゼロであり、気液界面領域が気体吸収の速度を制御するため、高い気体滞留と小さい気泡サイズが要求される (Advances in Chemical Engineering, Academic Press 1981, pp. 1-133)。気体と液体間の接触表面積を増加させることによって、より速い化学又は生化学反応速度が達成され、対応してより速い物質移動速度が達成される。
スパージャーは、単位体積当たり大きい表面積を有する小さい気泡を導入すること及び液体中の乱流レベルを増大させることによって、混合及び物質移動を促進するために、インペラーの下に配置される (Chemical Engineering Science, 92, (2014) 2191-2200)。他方、ジェットループリアクターは、2混合ノズルとドラフトチューブが取り付けられた容器である。該ノズルは、リアクターの上部又は下部に固定され得、該ドラフトチューブは、メインチューブと同心であってもよく、又はその隣にあってもよい。ノズル出口での液体ジェットは、非常に小さいサイズの気泡で気体を分散させる。液体の勢いによって、気液混合が循環し、デッドゾーンのないこれらの型のリアクターにおける良好な混合が起こる (Chinese Chemical Engineering, 22 (2014) 611-621)。
本発明は、不活性粒子の使用が、気液接触装置/リアクターシステム内での混合を促進し得ることを特定し、効果的な物質移動のための大きい気液界面領域を提供する。
