Methods for removing acid from Karamay heavy crude oil
Thread Content
The acid value of crude oil is very high; what equipment or additives can be used to remove the acid?
Alkali washing and alcohol-ammonia deacidification are both methods that render it practically meaningless; there is no need to remove acids from crude oil.
If the acid value is high, corrosion might be severe later on
Is it naphthenic acid? It can be separated using equipment
It’s naphthenic acid; what equipment is needed? Thank you
Naphthenic acids generally cause severe corrosion in high-temperature environments. I have a high-temperature corrosion inhibitor available here that proves to be quite effective against naphthenic acid corrosion
Using high-temperature corrosion inhibitors for anti-corrosion is the most economical and effective method; crude oil desulfurization is costly, requires significant investment, and does not yield such ideal results
