Minimum Liquid to Gas Ratio in Absorption Counter Current Operation (Lec096)

[@amazingdeen6734]

Thank You, Sir, for taking out the time to make the video for Separation processes

[@ChemicalEngineeringGuy]

Of course! I always wished it for myself as a student

Hello bro. Thanks for the video. Really informative. Kudos. I have a question. If I am constrained to use packed column to clean or scrub a gas + solid particles at the column inlet such that solid particles are to be removed or cleaned using water as the solvent or absorbent, can I still go ahead in using this method for calculating the tower properties (i.e NTU, HTU, equilibrium constant, liquid hold up etc). Thanks in advance bruv. Respect

[@ChemicalEngineeringGuy]

thanks for your comment! sure, you can use this method as a basic engineering approach, but for further design, you'll need to go full detail engineering

[@bayorasheed8314]

@@ChemicalEngineeringGuy Yes. You are right. I was just thinking that the available 2-film theory which most of these analyses are based is for gas-liquid scrubbing. but my case here is solids-liquid scrubbing.
I appreciate your reply.

Thanks really really a lot. I had a problem never solved by myself for 2 years. Ther e was no solution. But now I can solve it. Thanks. Can you tell me about the reference book of this video please?

Thanks alot sir..

Thank you!

How could you do it if you didn’t know the incoming gas flow rate, G?

[@ChemicalEngineeringGuy]

well... this must be a theoretical question, as you will typically know the requirements of that gas to "be cleaned up". That is, we design the equipment for this specific need.

Can I make x2=0 if I don't know how to properly specify it?

[@ChemicalEngineeringGuy]

Mm, you can't always assume x2 will be 0, but is you are certain that it is enough stream for it, sure, go ahead, although you should be making such raw guesses, it might help

Hi! Very informative video. I have a question though! So in my book there is a clear distinction between a limitation at the top or a limitation near the bottom of the seperator for mimimal flow. Does this have antyhing to do with wether or not the intersection of the equilibrium and the workline is over or under the molfraction at the top (y1). I'm sorry if my terms aren't correct they may be different (I speak another language). Kind regards

[@ChemicalEngineeringGuy]

Hi... Well, those limitations are real and typically modeled in more advanced courses. Stil, I don't get your question quite well, can you re-structure it?

Bruhh your accent is like a korean speaking english...

is that a bad thing?
