METHOD FOR REGENERATION OF ABSORBENT WORKED OUT IN CONGRUENT PROCESS OF BIO-ETHANOL DEHYDRATION

摘要

Using congruent process for dehydration of bio-ethanol, the worked out absorbent is regenerate by separation of water, not alcohol. The free water is separated by sedimentation, centrifugation or filtration, but bound water is separated by drying the material at a high temperature. The described process is more labour safety and human protective, it needs smaller energy consumption.
