Height Required to Ensure Liquid Disengagement
Height Required to Ensure Liquid Disengagement
(OP)
I'm sizing a vertical two phase separator (hydrocarbon gas / water). The vessel will not have a gas outlet mist eliminator.
What height should i allow above my vessel's max liquid level to ensure adequate liquid disengagement from the gas leaving the vessel's gas outlet?
Thanks.

Thanks for responding but...the linked thread does not discuss height above liquid for disengagement. The sizing equations simply define diameter. I'm already aware of the equations. The fact that they do not define height above the liquid level for liquid disengagement is my problem. Can my liquid level trip be 2 mm from the gas outlet as long as the diameter is ok?

Technically, the glass is always full - 1/2 air and 1/2 water.

We make use of Eaton separators a lot here. They're smaller than empty bed Souders-Brown separators, and work reliably without demister pads that might plug etc. They offer both cast units for use in lines, and larger fabricated stand-alone vessels. I forget the name of the original mfg that Eaton has eaten- it seems that Eaton, Tyco, Flowserve etc. are eating everyone these days.
