摘要
采用两种截留分子量的卷式纳滤膜组件研究了工业木糖溶液的纳滤过程 ,并在此基础上应用了S -K模型 .模拟计算结果表明采用纳滤方法浓缩水解法工业木糖粗品溶液 ,通过四级串联方式可将质量分数为 4 %的木糖溶液浓缩至 2 0 % .该技术操作能耗低 ,木糖回收率高 ,表现出良好的发展前景 .
Two types of spiral wound nanofiltration modules differed in cut-off molecular weights were used to study the nanofiltration process of rough industrial xylose, and the S-K nanofiltration model was established based on the experiments. The simulation showed that the xylose solution was concentrated from 4% to 20% through the 4-stage series connection configuration. The low energy consumption technology facilitated high recovery of xylose components, showing good potentiality.
