Horizontal Separator Sizing
Horizontal Separator Sizing
(OP)
I have designed Horizontal Separator for only liquid phase stream which is mostly water. And, i think the settling velocity of gas phase is too high. Vt= 12.85 m/s. Am i right? if yes, how to decrease this velocity. Do i need to use cyclone inlet device? what do you suggest me?
And one more question,
LAL-LAH can be taken as working level/NLL or not.Give a little explanation

Either increase pressure to reduce actual velocity or make your vessel a LOT bigger.
No LAL and LAH are ALARM levels.
NLL is normal Liquid level and is usally a single level somewhere between the two. Sometimes in the middle, sometimes more biased to one end rather than the other.
You sometimes get NLLL and NLLH to indicate normal variance in liquid level, but these should be within the limits of LAH and LAL.
The operators will not like you if they keep getting alarms going off for a "normal" variance in liquid level.

The diameter for vapor handling is too small ( 50mm) because of vapor flow rate. What i should do? Can i calculate dmin using overall volume flow using L/D = 2.5 standard?
L/D=2.5
V= 17.66 m3/h
V=AL = (piD^2/4)*2.5D
D=cuberoot(4V/2.5pi)
What to do in this situation?
