Multi-stage, adsorption process for separating organic liquids from water |
摘要 |
Organic liquid-water solutions, such as 5-30 W % alcohol in water, are separated efficiently in a two-stage adsorption process using a bed of selected adsorbent material in each stage to produce a concentrated organic product. Each adsorbent is selected to effectively adsorb the minor component from the feed solution and thus provide a dehydrated alcohol product. In the first-stage adsorber bed, activated carbon is used to selectively adsorb the alcohol, after which the desorbed alcohol vapor is passed to a second-stage adsorber bed of molecular sieve adsorbent for virtually complete removal of the remaining water. The process provides a dehydrated alcohol liquid product preferably containing less than about 2 W % water, and requires low energy usage.
