  2. Vacuum evaporation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_evaporation

    The vacuum evaporation treatment process consists of reducing the interior pressure of the evaporation chamber below atmospheric pressure. This reduces the boiling point of the liquid to be evaporated, thereby reducing or eliminating the need for heat in both the boiling and condensation processes.

  3. Leidenfrost effect - Wikipedia

    en.wikipedia.org/wiki/Leidenfrost_effect

    Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.

    en.wikipedia.org/wiki/Evaporation

    Water vapor is an invisible gas, but the clouds of condensed droplets refract and scatter the sunlight and are thus visible. Droplets of water vapor in a pan. Demonstration of evaporative cooling. When the sensor is dipped in ethanol and then taken out to evaporate, the instrument shows progressively lower temperature as the ethanol evaporates.

  5. Vacuum drying - Wikipedia

    en.wikipedia.org/wiki/Vacuum_drying

    This decreases the boiling point of water inside that product and thereby increases the rate of evaporation significantly. The result is a significantly increased drying rate of the product. [ 2 ] The vacuum drying process is a batch operation performed at reduced pressures and lower relative humidity compared to ambient pressure, enabling ...

  6. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. [1]

  8. Evaporator - Wikipedia

    en.wikipedia.org/wiki/Evaporator

    Because the cooling water, which is chemically treated fresh water, is at a temperature of 70–80 °C (158–176 °F), it would not be possible to flash off any water vapor unless the pressure in the heat exchanger vessel is dropped. A brine-air ejector venturi pump is then used to create a vacuum inside the vessel, achieving partial evaporation.
