Hi there,
Need a bit of help here... I need to model a horizontal liquid/gas separator, but all the separators that I find are the ones where there's an inlet on top where gas comes in with small droplets of water that fall down, and what I need is the inverse of this, an inlet from the bottom from where liquid comes in, and then small bubbles rise to the top...
and even from the droplet separator, I only find equations to get the size of the separator, and not other things like calculating the efficiency and so on...
I'm completely new to this topic, so can anyone recommend any book(s) and/or other literature for anything related to this topic, especially:
-Difference of Pressure from the bubble and the liquid, when the bubble is a mixture of gases (something to do with superficial tension?)
-How to calculate the efficiency of the separator (i imagine the rise velocity of the bubble, and the horizontal velocity of the liquid are important, but then?)
The info that I get is sizing of the separator, mass flow for the inlet, temperature, pressure, percentage of the different gases that make up the gas (hydrogen, water vapour, oxygen), details of the liquid (water+KOH)...
Anybody?

Hi ,
Did you try the search button ?
I've attached a xcelsheet from Art ,
For text book , I recommend : gas -liquid and liquid liquid Separators by Maurice Stewart and Ken Arnold .
Hope this helps

thanks for the reply...
but yeah, these are exactly my problems, the document you posted is for liquid/gas separation for droplets, what I need is a separator for bubbles...
and even then, I mostly only find information to calculate the sizing of the separator (like the document you posted, these are dimensions that I already have), and what I need is to calculate the efficiency of separation, which would be done by knowing what percentage of bubbles don't get separated...
but i might check that book you recommended, anybody else with an idea for the bubble separator?
