摘要
分子筛具有吸附性、再生性,热稳定性好。将浓度为95%Vol的酒精蒸汽进入分子筛吸附塔,水分子被吸附在分子筛的微孔内并被吸附除去,实现酒气脱水,可得到浓度为99.5%～99.9%Vol的无水酒精。酒精分子筛气相脱水工艺有利于酒精脱水和水分子的脱析,提高吸附脱水效率;可减少设备投资,生产运行耗电少;具有对酒精中色素的去除作用;分子筛可多次重复再生使用。(孙悟)
Molecular sieve has the advantages of good absorbability, reproducibility and heat stability. Alcohol vapor （concentration as 95 %Vol） treated by molecular sieve absorption tower could realize water removal and 99.5 %～99.9 %Vol absolute alcohol was produced. Molecular sieve gas phase dehydration could be used in alcohol dehydration, which could improve absorption dehydration efficiency, reduce equipment investment, and consume less electric energy. Besides, it could be used in pigment removal in alcohol and molecular sieve could be used repetitively. （Tran. by YUE Yang）
