Design of vapor-liquid separator (knockout drum, flash drum)
Jul 25, 2006· The size a vapor-liquid separator drum (or knock-out pot, or flash drum, or compressor suction drum) should be dictated by the anticipated flow rate of vapor and liquid from the drum. The following sizing methodology is based on the assumption that those flow rates are known.

Flash Distillation Christian Brothers University
Flash calculations are very common, perhaps one of the most common Ch.E. calculations. They are a key component of simulation packages like Hysis, Aspen, etc. When designing a flash system it is important to provide enough disengaging space in the drum. Drums can also be designed as cyclone separators.

Adiabatic Flash Drum with Binary Liquid Feed Wolfram
A high-pressure, hot, liquid mixture of methanol and water is fed into an adiabatic flash drum (or vapor-liquid separator). Because the flash drum pressure is below the bubble pressure, some of the liquid evaporates and the temperature decreases because energy is needed to evaporate the liquid. Thus, a vapor-liquid mixture in equilibrium exits
