英文名称：Natural gas — Gas chromatographic requirements for hydrocarbon dewpoint calculation
发布日期：2006-11
标准范围
This International Standard describes the performance requirements for analysis of treated natural gas oftransmission or pipeline quality in sufficient detail so that the hydrocarbon dewpoint temperature can becalculated using an appropriate equation of state. It can be applied to gases that have maximum dewpointtemperatures (cricondentherms) between 0 °C and – 50 °C. The pressures at which these maximum dewpointtemperatures are calculated are in the range 2 MPa (20 bar) to 5 MPa (50 bar). Major components aremeasured using ISO 6974 (all parts) and the ranges of components that can be measured are as defined inISO 6974-1. The procedure given in this International Standard covers the measurement of hydrocarbons inthe range C5 to C12. n-Pentane, which is quantitatively measured using ISO 6974 (all parts), is used as abridge component and all C6 and higher hydrocarbons are measured relative to n-pentane.
