PH function in HYSYS
PH function in HYSYS
(OP)
I use HYSYS to simulate my TEG dehydration project. This is a new design plant. My customer wants to know how much chemical (for PH control) to be initial fill to the system. As such, I have to estimate the PH value of the solution in order to determine the amount to be added.
I tried to add "PH" function under "property" in HYSYS. However, it showed " cannot be added". Someone told me PH function can only be used for certain fluid package. if true, what are the available fluid package? are the fluid package suitable for TEG dehydration system?
FYI
I am using Peng-Robinson as the fluid package for the system.

RE: PH function in HYSYS
You cannot really simulate the pH your glycol will get to as it is effected by all the following
1) contamination from non synthetic lube oils and chemicals from upstream
2) oxidation
3) CO2 in solution
4) TEG degradation
5) glycol losses and replacement
What I can tell you is on all the glycol systems I support the average injection of pH correctors is very small,in most cases zero and probably 12 litres a year would be an overstatement
