Flash evaporation Wikipedia

Flash evaporation of a singlecomponent liquid. The flash evaporation of a singlecomponent 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 singlecomponent liquid is vaporized.
