FLUID DISTILLATION APPARATUS HAVING IMPROVED EFFICIENCY

摘要

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 oth er horizontal tube heat exchanger.
