摘要尝试将膜蒸馏技术应用于水中同位素化合物的富集化。该工艺是在323-353K温度范围内与疏水性聚四氟乙烯(PTFE)平板微孔膜直接接触MD进行的。馏分油冷凝直接进入一股冷却水中。计算的瑞利蒸馏曲线与渗透实验结果的比较表明，分子蒸馏过程比简单蒸馏更有效地富集水中的重同位素。
Abstract An attempt to apply membrane distillation (MD) for the enrichment of water isotopic compounds was made. The process was conducted as a direct-contact MD with flat-sheet microporous, hydrophobic polytetrafluoroethylene (PTFE) membranes in the temperature range 323–353K. The distillate condensation was carried out directly into a stream of cooling water. The comparison between calculated Rayleigh distillation curves and the results of permeation experiments demonstrated the MD process to be more efficient than simple distillation for enrichment of the heavy isotopes in water.
