Abstract
Description
圧縮空気をエアリフトポンプに注入するための注入ポートと、
複数の穿孔を有する混合室であって、混合室は空気を注入ポートから受け入れるために注入ポートに結合され、且つ複数の穿孔を通して水を受け入れる混合室と、
混合室に流体接続されて混合室から延在するリフト筒と、
リフト筒に流体接続されてリフト筒から延在する吐出ポートであって、排気口と排液口とを有する吐出ポートと、
注入ポートと混合室との間に置かれた気体流入デバイスであって、気体流入デバイスは複数の穴が貫通延在する平坦な本体を有し、これらの穴は、注入ポートからの空気を混合室に流入させるために気体を複数の微細流にする寸法を有する、気体流入デバイスと、
を備える。
図1に示されているように、エアリフトポンプ10は、全般的に、注入ポート12と、注入室14と、混合室16と、リフト筒18と、吐出ポート20と、注入ポート12と混合室16との間に配置された気体流入デバイス50とを含む。
次に、気体流入デバイス50を詳細に説明する。気体流入デバイス50は、図2および図3に単体で示されている。
エアリフトポンプ10は、1つ以上のサチュレータシステムと同時に水の中で使用され得る。サチュレータシステムは、水相液体との気体交換を同じ水とインラインで行うように構成される。
これらの試験の実施には、以下を使用した。
・水タンク
・空気源(圧力依存)
・CO2源
・CO2溶解方法
・エアリフトポンプ10
・測定機器(CO2、温度、塩分濃度、圧力、空気流量、水流量)
第2の試験方法(試験方法2)は、試験方法1とほぼ同様であるが、エアリフトポンプ10から出る水流量の測定が不可能な状況において使用した。この方法は、エアリフトポンプ10が動作中のとき、平衡状態(すなわち、追加されるCO2と除去されるCO2とが等しくなる点)に達するまで、既知のCO2量をタンクに追加する必要があった。エアリフトポンプ10の頂部および底部における濃度を求めることによって、水流量を算出した。
