TL;DR: In this article, a method to calculate the viscosity of supercritical CO2 is introduced using a rolling body viscometer equipped with a gas booster and a new correlation is developed.

TL;DR: In this article, the authors proposed two new accurate simple explicit numerical methods for calculating the z -Factor and viscosity of natural gases, which can be directly assumed or used as an initial value of other implicit correlations.

TL;DR: In this paper, the authors developed a new accurate correlation to rapidly estimate gas compressibility factor (z-Factor), which is valid for gas coefficient of isothermal compressibility (cg) calculations also.

TL;DR: In this paper, a general investigation of the viscosity of natural gas as a function of temperature, pressure and composition was carried out to develop a generalized correlation, which was based on 3231 data points of 29 multicomponent mixtures in wide ranges of pressures (0.1-137.8 MPa), temperatures (241-473 K), and specific gravities ( 0.573-1.337).

TL;DR: In this article, the synergistic effects between methanol and a poly Vinyl Methyl ether as low dosage hydrate inhibitors were investigated and it was shown that a valuable effect was discovered at a certain ratio of methanoline to the low-dose hydrate inhibitor.
