摘要: The viscosity of natural gas has been evaluated by four methods: the Lohrentz–Bray–Clark (LBC), Pedersen et al. (PFCT), SUPERTRAPP, and Vesovic–Wakeham (VW) methods. predictions have compared with available experimental data that cover temperature range from 240 to 444 K pressures up 55 MPa. PFCT VW methods showed smallest rms deviations, while SUPERTRAPP were only marginally worse. results indicate these three are capable predicting an deviation 3% maximum deviations 5 6%. LBC method proved less reliable 8 9%.
