中文摘要: |
渗透蒸馏是适用于浓缩生物制品的一种新型膜过程.以NaCl—柠檬酸稀溶液为研究体系,对渗透蒸馏的传质过程进行了研究,实验结果表明,水通量大于67Kg/m2·d,柠檬酸可由300g/L浓缩到500g/L以上,同时还探索了渗透蒸馏和膜蒸馏浓缩柠檬酸的集成膜过程. |
英文摘要: |
Osmotic distillation is a novel membrane process for concentration of bioproducts. In this paper, the mass transfer process of osmotic distillation has been studied using NaCl-Citric acid dilute aqueous solution as experimental system. The experimental results show that the water flux is more than 67Kg/m2; d and the concentration of citric acid in feed solution can be concentrated from 300g/L to 500g/L.The integrated membrane process of osmotic distillation and membrane distillation for concentrating citric acid was also studied. |
