advantage of flash drum separator
Separation by Flashing . A mixture of two liquids or a liquid and vapor can be separated by passing it to a flash drum at a fixed temperature and pressure. The mixture is allowed to reach equilibrium (or near it), and then the vapor exits the top and the liquid exits the bottom of the drum.

Flash Separation. Flash separation is a technique used to separate the gas and liquid species in a stream that is at vapor-liquid equilibrium (VLE). Either the species can be at VLE before entering the separator, or the separator may add or remove heat to bring the system to …
Example 3.2 in that text shows how to analyze several types of flash separators. The mixture separated includes benzene, toluene and o-xylene. Thus we need property data for those compounds. Using start403a and start403b in Matlab we get a list of our compounds and can set three streams for our separator:

The separation of suspended solid particles from a liquid by gravity settling into a clear fluid and a slurry of higher solids content is called sedimentation. 2. Inertial and centrifugal separation This method is similar to sedimentation, but some forces are added in order to get a better separation.
