An Overview of Practical Aspects of the Design and Application of Polymeric/Ceramic Supports in Supported Liquid Membranes for Gas Separation

The idea of establishing faster/facilitated transport through liquid membranes (LMs) is both theoretically fascinating and promising for applications. One of the most selective, along with lots of desirable promising forms of LMs, is supported liquid membranes (SLMs). Since the introduction of the idea of SLMs a few decades ago, research activities in this sector have been continuously increased. Through a comprehensive analysis of the current state of the art, this review demonstrates the design and application considerations that must be made when determining whether to employ polymeric or ceramic supports in SLMs for gas separation. Following a thorough analysis of the principles of LMs, including their chronology, transport mechanism, and advantages and disadvantages are presented. The various configurations suggested up to date, their road from the laboratory to practical implementation, and their performance are discussed. Finally, potential challenges and opportunities are outlined.
