What is ISO 6327 - Determination of the water dew point of natural gas about?
ISO 6327 describes hygrometers used for the determination of the water dew point of natural gases by detecting water vapour condensation occurring on a cooled surface or by checking the stability of the condensation on this surface.
Who is ISO 6327 - Determination of the water dew point of natural gas for?
ISO 6327 on the determination of the water dew point of natural gas is useful for:
- Natural gas industry
- Testing laboratories
- Research institutes/ academia
Why should you use ISO 6327 - Determination of the water dew point of natural gas?
For both safe transport and use of natural gas, it is necessary to control the dew points of water and hydrocarbons in the natural gas stream.
The water dew point of processed natural gases in transmission lines normally lies between – 25 °C and + 5 °C, which corresponds to water concentrations of 50 to 200 ppm (V/V), according to the pressure of the gas.
The hygrometers considered in ISO 6327 may be used for determining water vapour pressure, without requiring calibration, in a system operating under total pressures greater than or equal to atmospheric pressure. The relationship between water vapour partial pressure and the observed dew point confers on the method the quality of absolute measurement.
ISO 6327 provides guidance on precautions to be taken when conducting the test, elimination of hydrocarbon condensates, correction of water dew points. This helps you to achieve the accurate results of test performed to determine water dew point of natural gases by detecting water vapour condensation occurring on a cooled surface.
