  • Multiple effect thin film distillation system and process
    Patent number: 4402793
    Abstract: A multiple effect diffusion distillation system includes a plurality of parallel plates for continuous recovery of heat having opposed evaporation and condensation faces for alternately evaporating and condensing phases of a liquid fed on to the upper end of the plates in a thin film for gravity flow along the evaporator face of the plates with vapor condensing on the condensation faces and with means for collecting and recovering the condensed product from the system. Alternate embodiments including a solar heat input system and others include multiple modular systems.
    Type: Grant
