Abstract
The separation of bubbles in the water/oil was tried using a hydrophobic PTFE/hydrophilic PVA membrane modules. The PTFE membrane was effective to recover the bubbles flowing the outside the fiber in the water into the fiber when inside of fiber was evacuated. The recovery rate, i. e. the gas permeation rate, depended on the gas flow rate, the length of fiber and the degree of vacuum. The recovery ratio which was defined by the recovery rate/the gas flow rate had a good correlation with the gas hold up. On the other hand, the bubbles in the oil were flowing up outside the fiber without any contact to the fiber, and only the oil containing no bubbles was recovered inside the fiber for PTFE membranes. From the results mentioned above this recovery method of bubbles would be available in the nongravitational field such as space station.
