GB/T 18609-2011 uses the potentiometric Titrimetric method to determine the acid value of crude oil, which is suitable for all kinds of crude oil. This method uses the principle of acid-base neutralization. During the titration process, with the addition of alkali, the acidic substances in the crude oil are neutralized, and the titration endpoint is determined by the change of potential. The standard specifies the requirements of the required Potentiometric titrator and other instruments, and specifies the preparation of titrants, solvents and other reagents. Detailed description of crude oil Sample Handling, such as sample weighing and dissolving steps. Standardize the titration operation process, including titration speed and potentiometric monitoring Frequency. According to this standard, the acid value of crude oil can be accurately determined, providing key data support for crude oil quality evaluation, processing technology selection
