When fluid flow through a restriction, for example valve or orifice, pressure drop occurs adiabatically. If changes in kinetic or potential energy are negligible, which causes no change in enthalpy at the inlet and at the outlet, then we have ΔH = 0. Some properties of throttling process are expressed in figure below.
In previous post, I shared about how to size two-phase horizontal separator. In this pos, I want to share to you how to size two-phase vertical separator.
Schematic of Two-Phase Vertical Separator
Figure below is schematic drawing of two-phase vertical separator.
