FROM POLYMER TO INDUSTRIAL SYSTEMS: A SURVEY OF 15 YEARS OF DEVELOPMENT IN MEMBRANES APPLICATIONS

摘要

In the area of Industrial Gases, membranes appeared about 15 years ago, facing the strong competition of classical technologies for gases purification and production: cryogenic distillation, absorption and adsorption. Today, Membranes based systems have definitely demonstrated their ability to play a major role in Industrial Gases activity: Nitrogen On-Site production, as well as Hydrogen recovery and Natural Gas treatments. This paper aims at presenting the main developments that have led to the present state of the art: polymers and hollow fibers improvements, bundles technologies, On-Site generators and equipment for Process Industries or specific applications.
