Abstract
A new type of liquid membrane, designated as a “flowing liquid membrane” is proposed, in which a liquid membrane solution flows in a thin channel between two microporous membranes. Separation of ethylene from ethane by flowing liquid membrane modules was carried out, in which silver nitrate was used as a carrier of ethylene. It was found that, compared with the usual immobilized liquid membranes, the flowing liquid membrane has higher permeability and stability. The mechanism of the facilitated transport of ethylene through the flowing liquid membrane was elucidated, and this successfully predicted the permeation flux as well as the selectivity. The performance of the membrane module was satisfactorily explained by the proposed design equations.
期刊介绍：
The Journal of Membrane Science is a publication that focuses on membrane systems and is aimed at academic and industrial chemists, chemical engineers, materials scientists, and membranologists. It publishes original research and reviews on various aspects of membrane transport, membrane formation/structure, fouling, module/process design, and processes/applications. The journal primarily focuses on the structure, function, and performance of non-biological membranes but also includes papers that relate to biological membranes. The Journal of Membrane Science publishes Full Text Papers, State-of-the-Art Reviews, Letters to the Editor, and Perspectives.
