Because of the intimate contact between liquid and vapor, the system in the flash chamber is very close to an equilibrium stage. The system is called вЂњflashвЂќ distillation because the vaporization is extremely rapid after the feed enters the drum.

A demister or entrainment eliminator is often employed to prevent liquid droplets from being entrained in the vapor. The vapor is taken off overhead, while the liquid drains to the bottom of the drum, where it is withdrawn. Because of the large drop in pressure, part of the fluid vaporizes. The fluid is pressurized and heated and is then passed through a throttling valve or nozzle into the flash drum.

The equipment needed for flash distillation is shown in Figure 2-1. Usually a large degree of separation is not achieved however, in some cases, such as the desalination of seawater, complete separation results. The more volatile component will be more concentrated in the vapor. In this process, part of a feed stream vaporizes in a flash chamber, and the vapor and liquid in equilibrium with each other are separated. One of the simplest separation processes commonly employed is flash distillation.
