WebApr 1, 2024 · Flash evaporation is a process by which some of a liquid instantly boils — or flashes — after it has been heated and sent through a chamber that has reduced pressure. It is the reduction in pressure that results in some of the liquid vaporizing. Vaporizing a liquid in such a way absorbs heat and can cause the surrounding area to cool drastically. WebThe flash point is therefore dependent on the boiling point and consequent vapor pressure of the liquid.

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 of the simplest unit operations. If the throttling valve or device is located at the entry into a pressure vessel so that the flash evaporation occurs within the vessel, then the vessel is often referred to as a flash drum. WebOct 6, 2024 · Temperatures and vapor fractions along the crude preheat train depend upon composition and the heat exchanger network.

All liquids have a specific vapor pressure, which is a function of that liquid's temperature and is subject to Boyle's Law. As temperature increases, vapor pressure increases. As vapor pressure increases, the concentration of vapor of a flammable or combustible liquid in the air increases. Hence, temperature determines the concentration of vapor of the flammable liquid in the air. A certain concentration of a flammable or combustible vapor is necessary to sustain combustion i… WebAug 8, 2024 · A certain concentration of vapor in the air is necessary to sustain combustion, and that concentration is different for each flammable liquid.
