Flash evaporation - Wikipedia
Flash evaporation. A typical flash drum. 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 …
Vapor–liquid separator - Wikipedia
A vapor–liquid separator may also be referred to as a flash drum, breakpot, knock-out drum or knock-out pot, compressor suction drum, suction scrubber or compressor inlet drum, or vent scrubber. When used to remove suspended water droplets from streams of air, it …

What is flash drum and their uses in Oil and gas.
Feb 25, 2023 · A flash drum is a type of separator used in industrial processes to separate two or more liquids or a liquid and a gas mixture. It is also known as a flash separator, flash vessel, or vapor-liquid separator.
Flash Drums: Design Principles & Operation | Vaia
Flash Drum Definition: A vessel used to separate a multi-component liquid mixture into vapor and liquid phases through a pressure drop or temperature rise. Flash Drum Design Principles: Essential considerations include vapor-liquid equilibrium, pressure and temperature settings, drum size, and flow rates.
Flash distillation. Flash evaporation is one of the simplest separation processes. A liquid. stream containing several components is partially vaporised in a " ash drum" at. a certain pressure and temperature. This results in two phases: a vapor phase, enriched in the more volatile components, and a liquid phase, enriched in the.
Design of a vapor-liquid separator drum (or knockout pot, or flash drum …
Sep 9, 2005 · In Metric units: A vapor-liquid separator drum is a vertical vessel into which a liquid and vapor mixture (or a flashing liquid) is fed and wherein the liquid is separated by gravity, falls to the bottom of the vessel, and is withdrawn.
Flash Vessels: Calculation, Definition, Working Principle, Function ...
Flash vessels, or flash drums, are essential components in many chemical engineering processes, especially in the separation of vapor-liquid mixtures. They play a critical role in refining, petrochemical, and other industrial applications.
Flash Distillation in Chemical & Process Engineering
Understanding the concept behind Flash Distillation, the vapor-liquid equilibrium and all other mass transfer interaction will allow you to understand and model Flash Drums and Flashing Systems.
Flash distillation is used to separate components in a mixture making use of the difference in their volatilities. The operation consists of partially vaporizing or condensing the mixture by either heating or cooling the feed and separating the vapor from the liquid in …
