Supersonic Separators for Natural Gas Processing: Real Gas Effects

摘要

The ideal gas law and Redlich-Kwong real gas model were used toanalyze the gas dynamics parameters of natural gas flows in thesupersonic separators with the standard k-ε model. The effects of inletpressures on the natural gas characteristics were computationalsimulated with ideal gas and Redlich-Kwong equation of states. Theresults show that the ideal gas and Peng-Robinson models predict thesame gas parameters in the subsonic zone, while the ideal gas resultdiverges from the Redlich-Kwong case in supersonic zones.
