brown-sudders equation calculator

the souders–brown equation (named after mott souders and george granger brown) is a tool for obtaining the maximum allowable vapor velocity in a vapor-liquid separation vessel (also called flash tank, knockout tank, knockout tank, compressor suction tank) . and compressor inlet drum). for the same purpose, it is also used in the design of plate fractionation towers, plate absorption towers and other gas-liquid contact towers.

a vapor-liquid separator is a vertical vessel into which a mixture of liquid and vapor (or flash liquid) is fed. the liquid separates by gravity, falls to the bottom of the vessel, and is then discharged. the vapor moves upward at a design speed that minimizes any entrainment of liquid droplets as the vapor leaves the top of the container.
