hi

i want to simulate a reactor carring the hydrogenolysis of methyl formate to methanol, the reaction is

CH3OOCH + 2H2 --------> 2CH3OH

Methyl formate + Hydrogen ------> Methanol

the operation condition as follows

temp 100-140 C

Hydrogen pressure 30-60 bar

Co Pressure 0-20 bar

Catalyst loading 8-20 G/L

Methyl formate Concentration 05-15 Mol/L



Co is a product comes from the stream before the Hydrogenolysis unit

Co is inhibiting the catalyst activity ....

the problem is that i have a kinetc equation describe the reaction rate ...

but it has a pressure terms and concentration terms

and as you know hysys dealing with all term in concentrations or partial pressure

as you can see in the pic




and this is the rate equation



now this equation has a term for partial pressure and also concentration

now i want to convert the pressure terms to concentration

HINT

this can be done by

nonlinear least square minimizing method

but i don't know how to proceed ....

i need help on this

regarding the reactor size and pressure drop this step is not important

in want to run the reactor first

thanx alot
