- •
The GERG-2008 EOS was tested against recently published low temperature data for (methane + butane).
- •
A simpler departure function reduced the maximum cp deviation at T = 120 K from (110 to 7) %.
- •
Improved BIPs for (methane + butane) were determined by re-fitting to an extended data set.
- •
Deviations for high pressure VLE data at T = 244 K were reduced from (9 to 1.4) %.
