Title: Barometric evaporation process and evaporator

Abstract: A process for the evaporation of an available warm or hot liquid under a vacuum by applying a pressure drop thereon initiating flash-down evaporation, and followed by further flash-down evaporation under an applied pressure gradient whereby the residual liquid is raised by the vapor produced to an elevation sufficient for subsequently discharging the residual liquid from vacuum without a pump; and by separating the vapor phase from the residual liquid phase before condensing the vapor produced into distilled liquid.
