Dissolved gases 1

[Scoi]

I'm looking to create a model of dissolved gases in water. I have around 20 compound which i need to find out what mass/vol/mol is dissolved in water at a given T and P.

My initial plan was to use the Henry's law coeffs but that would only be valid for a binary solution.

Does anyone know of a method that i can use for multi componant? HYSYS seems incapable of taking dissolved gases into account unless someone knows better.

Also, my Henry's coefficients seem to be lacking for the heavier componants. NIST provides one of the coefficients but not the other, does this mean it has zero solubility, should the other number be 0,1, X?

Cheers

Gases are sparingly soluble, so Henry's Law will apply unless the gases are reactive with water.

Dilute solutes don't interact with one another unless they react with water and/or with one another, i.e. chlorine and ammonia.
