Water vapour may be present in natural gas due to, for example, natural occurrence in the well production stream,
the storage of gas in underground reservoirs, transmission or distribution through mains containing moisture or
other reasons.
This International Standard specifies a method of determining the water content of natural gas under pressures of
more than 1 MPa, the upper pressure limit being determined by the maximum pressure that the apparatus can
withstand. It is applicable to sweet natural gas and sour natural gas, containing hydrogen sulfide, with a water
concentration of 10 mg/m3 or more.
NOTE - Test data may be affected by alcohols, mercaptans, hydrogen sulfide and glycol contained in the sample gas, as
these compounds react with the phosphorus pentoxide (P205) used to absorb the water vapour in the gas.
