Two Phase Separator

A two phase separator is used to separate fluid into gas and liquid.

Separation of the liquid and gas starts when the fluid meets the baffle.  At that point, the gas and liquid start to go in different directions.  The liquid drops where it is collected at the bottom of the vessel, and the gas rises to the top of the vessel. The gas that is still held in the liquid is in a section called the gas/liquid emulsion, which is in an area at the top of the liquid.  In time, the gas is released from the emulsion and rises to the top of the vessel where the rest of the gas resides.  Depending on the process, this may contain a mist eliminator or demister.  The gas leaves from the top of the vessel, and the liquid leaves from the bottom of the vessel, heading to the next process.
