Study of Compression Factor of Natural Gas in Superhigh Pressure and Multiple Source Networks

Compression factor of natural gas must betaking account of when doing hydraulic calculations in super high pressure network. Several calculation methods and features of compression factor of natural gas were discussed. The compression factor of natural gas in a super high pressure and multiple source network was calculated separately by fitting S-K nomogram and state equations, then weighted average according to the quantity of gas supply of each source. Results indicate that hydraulic calculation of super high pressure and multiple source network, chosing calculation methods of compression factor of natural gas resonably is critical.
