Abstract
Steam is popular heat medium used in industry. Here, steam recovery via vapor permeation (VP) technology was reviewed from water and heat utilization point of view. Initially, VP is compared with other steam recovery technologies, including heat exchanger, desiccant, membrane condenser and transport membrane condenser. Subsequently, VP membrane materials for steam/gas separation at temperature exceeding 150 ℃ are summarized. The review concludes with an introduction of potential applications of VP steam recovery.
