# Amount of component x condensed along with water vapour during reaction

## Amount of component x condensed along with water vapour during reaction

(OP)
Hello all,

I want to calculate amount of component x condensed along with water vapour during reaction. The reactor batch is 10 tonne.

The reaction takes place at 180 degC at which component x is removed and condensed.

Vapour pressure of the component x at 180 degC = 0.001
Vapour pressure of water at 180 degC = 10 bar

Molecular wt of component x = 300 g/mol

### RE: Amount of component x condensed along with water vapour during reaction

You should condense 0.001 cc of component X vapor for every 10 cc of water vapor. Now convert cc's to mass units for each component.

### RE: Amount of component x condensed along with water vapour during reaction

Using simple rules such as Raoults Law to compute the water condensed would be appropriate only if the reaction mix is ideal - for non ideal mixes, there would be significant deviations.

### RE: Amount of component x condensed along with water vapour during reaction

A condenser will significantly sub-cool the condensate so this is not an equilibrium problem.

Thanks all,

I don't think Raoult's law would be applicable here.

Please let me know if my calculation below is correct

Here, X is mass % of component x

((X⁄300))/((((100-X))⁄18) )=0.001/10

((X⁄300))/((((100-X))⁄18) )= 0.0001

x/300=(0.0001*(100-X))/18

18X=0.03*(100-X)

18X=3-0.03X

X=1.66%

Thanks

I don't think above calculations is correct though. Any input would be highly appreciated.
