Abstract

New and accurate viscosity measurements of three natural gas mixtures obtained directly at three different locations in the Norwegian gas transport network in the North Sea are presented. The viscosity measurements were performed using a vibrating-wire instrument with an uncertainty of  ± 1%, and covered a wide range of temperatures and pressures (263–303 K and 5.0–25 MPa). The predictive power of various models was also examined in relation to our new viscosity measurements. It was found that one of the Lee–Gonzalez–Eakin variants, as well as the NIST’s SUPERTRAPP scheme, agreed very well with the present measurements. The correlative schemes reported by Schley et al. (Int J Thermophys 25:1623, 2004) and Vesovic–Wakeham (Int J Thermophys 22:415, 2001) were found to deviate significantly from the present measurements.
