Because of the tendency of the heavier components of crude oil to crack at high temperatures, the temperature of the feed furnace is controlled to be no higher than 700 F.
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.

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. slow group angersWebDetermine the composition of the vapor and liquid phases at the flash point.
