摘要
渗透蒸馏技术是一种渗透过程与蒸馏过程耦合的新型分离技术 ,它具有投资省、能耗低的优点 ,特别适合处理热敏性物料的分离。本文对渗透蒸馏过程的热力学、动力学原理及其在食品、医药、生化、化工等领域的应用作了简要综述。
Osmotic distillation is a new seperation technique that the distillation combined with osmotic at low temperature. In this paper ,the osmotic distillation thermodynamics,osmotic distillation kinetics,and application of osmotic distillation are reviewed.Today osmotic distillation in the concentration of natural juices and membrane distillation in various other applications are still attracting a growing attention. However,for lowering energy cost ,the process is optimized as combination of osmotic distillation with ultra-filtration or reverse osmotic distillation by step by step.
