WebLevy et al. [18] developed a simplified homogeneous non-equilibrium flashing model. When there is a rapid pressure decrease along the flow direction, this model may be applicable. This model assumed that water should be superheated at a given local pressure before liquid flashed into steam and enough vapor would be generated to reduce the water WebFlashing occurs when liquid flows through a control valve and vaporizes, remaining a vapor. Flashing shares some common features with choked flow and cavitation in that the process begins with vaporization of the …

WebEquilibrium flash calculations distillation The emphasis on vapour-liquid equilibria (including vapour pressure) is inherant in the petroleum industry due to the importance of distillation in separations. If separations by extraction are to be undertaken, then liquid-liquid equilibrium is equally important. Fugacities for thermodynamic equilibrium (flash …
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. $${\displaystyle X={\frac … See more Flash evaporation (or partial evaporation) is the partial vapor that occurs when a saturated liquid stream undergoes a reduction in pressure by passing through a throttling valve or other throttling device. This process is one … See more Spray drying is sometimes seen as a form of flash evaporation. However, although it is a form of liquid evaporation, it is quite different from flash … See more • Evaporator • Vapor-liquid separator • Multi-stage flash distillation See more The equilibrium flash of a multi-component liquid may be visualized as a simple distillation process using a single equilibrium stage.
