Hello,

I am looking to calculate the critical properties as well as the following physical properties for a 23000 ppm brine at T=95 C and P=282 atm:

Viscosity
Compressibility
Density
z-factor

I've seen some correlations in the literature but would like to be more exact. I'm wondering if anyone knows of a good online software package so that I can automate this process for several different scenarios.

Thanks,

Marlo

I think you may need to be more specific.
A literal interpretation might assume you could refer to either sodium chloride brine or potassium chloride brine. But the term "brine" also has become a generic for any refrigerant. For example, in pharmaceutical applications where brine (NaCl solution) was once used as a refrigerant the term is used generically to refer to ethylene glycol solutions.
Various industries have many such generic terms that can mean different things to different people.

Hi JMW, thanks for your reply.

This is for a geologic application and it's safe to assume an NaCl solution. A brine we define as >30,000 ppm NaCl so this is technically more like seawater. Does this help?

For anyone interested, I ended up using a spreadsheet from the following website:
