- Scope
- This standard specifies the direct determination of water in crude oil using the Karl Fischer potentiometric titration method. This standard is applicable to the determination of water in crude oil. For crude oil with mercaptan sulfur or divalent sulfide ion sulfur content or the total amount of both less than 0.05% (mass fraction) but more than 0.005% (mass fraction), water The determination range is 0.05% (mass fraction) to 2.00% (mass fraction); for crude oil with mercaptan sulfur or divalent sulfide ion sulfur content or the total amount of both is less than 0.005% (mass fraction), water determination The range is 0.02% (mass fraction) to 2.00% (mass fraction).
