Dear 7604
Using the boiling point and Marrero & Gani property prediction to genererate pseudo-data I estimated the constants to:
Model: Psat(bar) = 10^[A - B/(T(K) +C)]
A = 4.2950236336E+000
B = 1.3220367966E+003
C = -5.5900317428E+001

Dear Tp51
There are various options for doing this.
1. Use group contribution approach available online (eg: http://www.capsolva.dk/propertypredict.asp)
2. More advanced "plotting" approches based on whatever solubility data you have available.
For calculating direct solubility one can use...

This is more or less what you want right ?

Dear 1BT
From my experience a static mixer combined with a good quality conductivity meter (eg. http://www.endress.com/) is good solution. However it might be a problem finding a CT with a built-in (and temperature corrected) NaOH concentration calculation covering the range up and above 23% -...
Dear LaSalle1940
I guess you are hunting for solvents :)
I might be able to do a filtered search on fairly big database -- you would only need compounds miscible with water at ambient conditions? and results as CAS-NO/name ? Reply in this thread or by email if you still need the list.
The...
In short terms your are feeding your column at a sub-optimal point (compared to the initial simulation). In order to investigate the behaviour I suggest creating a small series of simulations where you vary the amount of feed preheat and feed-location and record the resulting RR.
You should see...
