Natural gas - Determination of water by the Karl Fischer method - Part 2: Titration procedure (ISO 10101-2:1993) EN ISO 10101-2:1998

Publication date:   May 14, 2000

Scope

The principle of the method specified is passing a measured volume of gas through a cell containing a relatively small volume of absorbent solution. Water in the gas is extracted by the absorbent solution and subsequently titrated with Karl Fischer reagent. The design of the cell and the absorbent solution are chosen so as to ensure efficient collection of the water at the high flowrates necessary. Is applicable to water concentrations between 5 mg/cm^3 and 5000 mg/cm^3.
