Abstract
ne"> In this paper, the thermal properties including molar heat capacity, CP, thermalconductivity, λ, and thermal diffusivity, αD, of the pure physical solvents sulfolane(SFL), N,N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), ethylene glycol(ETG), choloroform (CCL3H), acetonitrile (CH3CN), and pure chemical solventsmonoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA),methyldiethanolamine (MDEA), 2-amino-2-methyl-1-propanol (AMP) which all areextensively used in natural gas refinery processes were measured at temperaturesranging from (303.15 to 353.15) K and atmospheric pressure. All experimentalmeasurements were carried out by using a PSL Systemtechnik instrument in whichtransient hot-wire method was employed to measure transport properties, λ and αD. Allobtained data were correlated by using empirical linear temperature function with avery good correlation coefficient, better than R2 = 0.99. Among the solvents tested inthis paper, except for TEA, the thermal diffusivity decreased by increasing temperatureand also except for TEA and ETG, thermal conductivity decreased with temperature.
