GB/T 11146-2009 Crude petroleum—Determination of water—Coulometric Karl Fischer titration method
Abstract
1.1 This standard specifies the method for directly determining the water content in crude oil using the Karl Fischer coulometric titration method.
1.2 For crude oil with a content of mercaptan sulfur or divalent sulfide ions, or the total amount (mass fraction) of both, ranging from 0.005% to 0.05%, the measurement range for water (mass fraction) is 0.050% to 5.00%; for crude oil with a content of mercaptan sulfur or divalent sulfide ions, or the total amount (mass fraction) of both, less than 0.005%, the measurement range for water (mass fraction) is 0.020% to 5.00%.
