  • Fluid distillation apparatus having improved efficiency
    Publication number: 20070108038
    Abstract: Distillation apparatus comprises a condensing chamber and a heating chamber arranged on an enclosure. Liquid feed into the condensing chamber is pre-heated and flows to the heating chamber where it is boiled to produce vapor. Gas sparging in the condensing chamber enhances heat transfer and absorbs additional vapor generated by pre-heating. The condenser is a helical or other horizontal tube heat exchanger.
