ABSTRACT:
An apparatus for concentrating aqueous solutions of hygroscopic organic liquid having boiling points higher than the normal boiling point of water is disclosed. The apparatus includes an airtight evacuated chamber, means for injecting a preheated temperature adjusted solution into the chamber to vaporize water from the solution and produce a concentrated aerosol of organic liquid, and means for coalescing the concentrated aerosol. Also included is a system for recovery of organic vapor leaving the chamber along with the vaporized water.
