Liquid-liquid extraction system to recover acetic acid from waste water

Modular absorption system to recover a cocktail of solvents from a vent gas stream

Environmental Processes

Kuhni uses regenerative techniques for the recovery of valuable components from waste water and vent gas streams.

Waste water examples:

  • Stream stripping to remove volatile components

  • Liquid/liquid extraction to remove non-volatile components

Vent gas examples:

  • Absorption of water soluble components with water and subsequent steam stripping for recovery

  • Absorption of complex mixtures of largely non-water soluble components with high boiling oils and subsequent steam stripping for recovery
