摘要:

渗透蒸馏是一种渗透过程与蒸馏过程藕合的新型膜分离技术,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.对渗透蒸馏过程,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.目前,渗透蒸馏已经引起天然物质提取方面的科技工作者的广泛关注.由于渗透蒸馏过程速率较慢,出于经济效率考虑,一般要采用超滤或是反渗透对被处理物料进行初步浓缩,然后用渗透蒸馏对其进行高倍浓缩,采用组合流程较为有效.

Abstract:

Pervaporation distillation is a new membrane separation technology that combines osmotic process and distillation process, which has the advantages of saving investment and low energy consumption, and is especially suitable for the separation of heat-sensitive materials. The thermodynamics and kinetic principles of osmotic distillation process, and their application in food, medicine, biochemistry, chemical industry and other fields are briefly reviewed. At present, osmotic distillation has attracted widespread attention from scientific and technological workers in the extraction of natural substances. Due to the slow rate of pervaporation distillation process, for economic efficiency, ultrafiltration or reverse osmosis is generally used to initially concentrate the treated material, and then it is highly concentrated by pervaporation distillation, and the combined process is more effective.
