| 摘要 |
The present invention provides a system and a process for the recovery of an organic solvent from a mixture of an organic solvent and water. The process comprises subjecting an organic solvent/water mixture to a distillation system whereby a vapor is produced. The output from the distillation process passes through a filtration unit which comprises a hydrophilic membrane filter. The solvent/water mixture passing through the filtration unit is separated into a concentrate and a permeate. The concentrate (containing mostly organic solvent) can be collected, can be routed to the distillation system for further purification, or can be routed to a second filtration system for further purification. The permeate (containing mostly water) is routed from the filtration unit to a condenser where it is condensed and collected.
