GB/T 21069-2007Natural gas -- Determination of water content at high pressure (English PDF)

GB/T 21069-2007 is the English-translated version of 天然气 高压下水含量的测定.

GB/T 21069-2007 — The presence of water vapor in the gas may, for reasons including gas recovery fluid inherent, or natural gas storage in underground gas storage in stream by transmission and distribution water mains gas and so on.

This standard specifies the method for the determination of gas when pressure is higher than 1MPa water content, which is the upper limit depends on the pressure testing device can support Subject to the maximum pressure.

This standard applies to the water content of not less than 10mg/m3 of sulfur-free gas and acid gas containing hydrogen sulfide. This standard reference conditions for the measurement of gas volume 293.15K, 101.325kPa.

Note. The test data can be affected by alcohol, mercaptan, hydrogen sulphide and ethylene glycol contained in the sample gas, because these compounds will be absorbed by the sample and gas Moisture phosphorus pentoxide (P2O5) react.
