An improved method for calculating critical temperatures and critical pressures in natural gas mixtures with up to nC11 hydrocarbons

open access: yesOil & Gas Science and Technology, 2019
This study suggests an improvement to the empirical model proposed by Peng (1986, Can. J. Chem. Eng. 64, 827–830) to calculate critical temperatures and critical pressures in natural gas mixtures. It aims to extend its application to natural gas mixtures
