What is ISO 23874 - Hydrocarbon dewpoint calculation in natural gas industry about?
ISO 23874 is a standard covering hydrocarbon dewpoint calculation in natural gas industry, ensuring reliable repeatability of the measurements in natural gas industry applications.
ISO 23874 describes the performance requirements for analysis of treated natural gas of transmission or pipeline quality in sufficient detail so that the hydrocarbon dewpoint temperature can be calculated using an appropriate equation of state.
ISO 23874 is applied to gases that have maximum dewpoint temperatures (cricondentherms) between 0 °C and – 50 °C. The pressures at which these maximum dewpoint temperatures are calculated are in the range 2 MPa (20 bar) to 5 MPa (50 bar).
ISO 23874 covers the measurement of hydrocarbons in the range C5 to C12. n-Pentane, which is quantitatively measured using bridge component, and all C6 and higher hydrocarbons are measured relative to n-pentane.

- Drilling engineers
- Hydrographic surveyors
Why should you use ISO 23874 - Hydrocarbon dewpoint calculation in natural gas industry?
For hydrocarbon gas mixtures such as natural gas, the phase boundary or dewpoint line distinguishing single-phase gas from gas-liquid mixtures are a complex function of pressure, temperature, and composition.
ISO 23874 provides users guidance on principle, materials, apparatus, performance requirements, sampling, analytical procedure, methods of test, uncertainty in composition, calculation of dewpoint temperature, enabling the accurate assessment of hydrocarbon dewpoint.
ISO 23874 assists the user with the calculation of dewpoint temperature. ISO 23874 also assists with the calculation of fraction quantities, calculation of the composition, and calculation of fraction quantities and properties.
Adoption of ISO 23874 enables users to calculate hydrocarbon dewpoint calculation, enabling users to control hydrocarbon dewpoint, ensuring pipeline efficiency and maintenance requirements in the natural gas industry.
