May 19, 2020 · Flash evaporation can also be utilized are the production of biofuels. At different stages in biofuel production, a manufacturer may need to remove one liquid from another. In such a case, flash evaporation can be used to remove the more volatile—that is, a liquid that more easily evaporates—from the remainder of the liquid.

Flash evaporation - Wikipedia

Flash evaporation - Wikipedia

The flash evaporation of a single-component liquid is an isenthalpic process and is often referred to as an adiabatic flash. The following equation, derived from a simple heat balance around the throttling valve or device, is used to predict how much of a single-component liquid is vaporized.
