122 気泡ポンプ効果を利用した低純度二酸化炭素ガス処理システムの特性(流体機械1) 122 Characteristics of Sequestration System of Low-Purity C0_2 Gas Based on a Gas-Lift Pump
The global warming problem caused by increase of CO_2 in the atmosphere is getting tangible. Gas Lift Advanced Dissolution (GLAD) system has been newly developed to mitigate the global warming. The system dissolves low-purity CO_2 gas in seawater and sequestrates CO_2 at the deep ocean. The present paper describes basic characteristics of the system for pure and low-purity CO_2 gases. Performance of dissolution, liquid phase velocity, mass transfer coefficient, profile of void fraction will be discussed as functions of the gas injection rate. In addition, a relationship between mass transfer coefficient and bubble interfacial dynamics in the system will be discussed.
