Scope

This standard provides a mathematical model for obtaining the compression factor of crude oil and petroleum products, the calculation steps, and a compression factor table. The aim is to use the compression factor to convert the hydrocarbon volume measured at the metering temperature from the volume measured under pressure conditions to the corresponding volume under equilibrium pressure. The compression factor table specified in this standard is related to the metering temperature and the density of the metered medium at 15°C, with a temperature range of -30°C to 90°C and a density range of 638 kg/m3 to 1074 kg/m3. This standard also provides a compression factor table that can be directly retrieved based on the metering temperature and the density at 20°C, with a temperature range of -30°C to 90°C and a density range of 634 kg/m3 to 1074 kg/m3. This standard does not include the compression factor of lubricating oils.
