What concentration of acetic acid?
(OP)
We need to pump acetic acid into our process, but when I got the cost estimate for a mass flow meter, it was extremely high. It was so high because of the Hastelloy C needed for glacial acetic acid. So, what concentation can I feed without using an exotic stainless steel? 25% is not considered corrosive, but this dilute is inconvenient.





RE: What concentration of acetic acid?
Do you need to use a mass flow meter? There are other types of flow meters that are not as expensive, such as orifice plates and electromagnetic flow meters. Are you using Hastelloy C for the pump and piping? If you are using 316SS then you could most likely use that for the meter. However, you should consult with a metallurgist.

I will try to post a link in the metallurgy section.
