Abstract
A distillation system and process for removing vaporizable components from an aqueous medium including a distillation column for receiving an aqueous medium containing vaporizable components and passing steam through the column such that the steam directly contacts the aqueous medium to vaporize at least a portion of the components, a condenser in a communication with the column to condense at least a portion of the vapor in the column, a separator in communication with the condenser to separate flash vapor from liquid condensate in the separator and a thermal compressor in communication with the separator and the column to remove vapor from the separator and to inject exhaust steam from the thermal compressor into the column.
Claims10
A distillation process for removing vaporizable components from an aqueous medium comprising:
- a. introducing an aqueous medium containing vaporizable components into a distillation column for removing a portion of the vaporizable components from the aqueous medium.
- b. passing through the aqueous medium a current of steam from a thermal compressor to vaporize at least a portion of the vaporizable components,
- c. passing at least a portion of the vapors from the distillation column through a first space of a first condenser means having a first and second space sufficient to condense at least a portion of the vapors to a condensate.
- d. passing a recirculation liquid to the second space of the condenser means and from the condenser to a separator to separate steam from aqueous liquid, and
- e. passing the steam from the separator through the thermal compressor to form steam for introducing into the distillation column.
