Vacuum evaporation - Wikipedia
WEBVacuum evaporation is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal.
Vacuum Evaporation - an overview | ScienceDirect Topics
WEBVacuum evaporation is one of the most commonly used methods for deposition of functional films on to various substrates. The vacuum is used to allow vapor particles to deposit directly on to the substrate, where vapor particles condense back to a solid state, forming a functional coating.
WEBVacuum Evaporation. Introduction. The objective is to controllably transfer atoms from a heated source (which can be a liquid or a solid) to a substrate located a distance away to grow a film. The source is heated directly or indirectly until the point is reached where it efficiently sublimes or evaporates.
The basis of vacuum evaporation | Condorchem Enviro Solutions
WEBVacuum evaporation is a technique which is characterized by transforming liquid effluent into two flows, one of high quality water and the other comprising a concentrated waste. The water obtained is of sufficiently high quality to be re-used, whereas the waste can be concentrated, even reaching almost total dryness.
Vacuum Evaporation - an overview | ScienceDirect Topics
WEBVacuum evaporation is a process where a solid material is deposited on a heated surface through a thermal process under low pressure conditions, leading to the condensation of atoms or molecules on a cooler surface.
The Essentials of Continuous Evaporation - AIChE
WEBVacuum systems also remove noncondensible gases that originate as dissolved gases in the feed or from air leaking into the evaporator body. Most evaporation systems include either a direct or indirect water-cooled condenser to condense the vapor leaving the last evaporator effect.
Understanding Concentration and Evaporation Technology: …
WEBFeb 6, 2013 · Therefore, vacuum concentrators apply vacuum in the system to decrease a solvent’s boiling point so that liquid vaporization occurs at lower temperatures, e.g., water boils at –7.5 °C at 10 mbar pressure.
Vacuum Evaporation - an overview | ScienceDirect Topics
WEBVacuum deposition (or vacuum evaporation) is a PVD process in which the atoms or molecules from a thermal vaporization source reach the substrate without collisions with residual gas molecules in the deposition chamber. This type of PVD process requires a relatively good vacuum.
Vacuum Evaporation - SpringerLink
WEBEvaporation in high vacuum uses evaporation sources to heat up the coating material until a sufficiently high vapour pressure is attained, so that a desired evaporation rate is reached. The vapour pressure that develops over a liquid or by sublimation of a solid material, is a function of temperature.

WEBVacuum evaporation process is a wastewater treatment method that separates water from contaminants with high boiling points. Wastewater is then fed into a boiling chamber and heated until the water molecules turn into vapor.
