ActiveDetermination of acid number of crude oil by potentiometric titration
原油酸值的测定 电位滴定法
Application Summary AI generated
This standard specifies the potentiometric titration method for determining the acid number of crude oil, which measures the amount of base required to neutralize acidic components in the sample. It is applied in the petroleum industry for quality assessment and processing control of crude oils, particularly in refineries and laboratories to evaluate corrosivity and suitability for downstream operations. The method is used for crude oils with acid numbers ranging from 0.05 mg KOH/g to 50 mg KOH/g, ensuring accurate and reproducible results for both light and heavy crude types.
