2013-9-9 The gas gravity separation section then provides preconditioning of the gas—and its entrained liquid load—ahead of the mist extractor. Two approaches to sizing this part of the separator to remove liquid droplets from the gas are the K s method (Souders-Brown equation as shown in Eq. 1) and the droplet settling theory.

How to Design a Vertical Separator Process Phase

As a rule of thumb, select a vertical type if the gas to liquid ratio (V/L) is high. Overly, there are two major parameters, which have to be determined: Separator’s height.
