I'm desperate, i have to design an absorption column and I can't find the solubility equilibrium curve between chlorine (gas) and water. I would like to find a curve y vs x or partial pressure vs concentration. can anybody help me?
Thanks

I may be missing something, but isn't it just linear? Henry's law? c = kp?

[ana]

well i guess that only applies for dilute solutions but i have a concentrated solution so I guess I have to use a equilibrium curve but I can't find it. Do you know what is the value for the Henry constant?if I don't find the curve I will have to use it.

Thank you very much.

Hello,
I suggest you use a simulation tool to establish this curve.

Aspen will help a lot.

Just input your stream data and operating condition.

Aspen will tell you the number of ideal stages.

geodome:

You are correct that a simulation model such as Aspen may solve Ana's problem. But then Ana has learned absolutely nothing.

A better answer would have been that she should do a library search for the data she needs and design her absorption column using that data. After that, she could use Aspen to check her work.

Often, it is harder to find the thermophysical or chemical data than it is to solve the problem analytically.
