Speed of sound measurements in (carbon monoxide + ethane) and (carbon monoxide + propane) gas mixtures at T = (260 to 350) K and up to 12 MPa Segovia Puras, José Juan Martín González, María del Carmen Paredes Mendez, Xavier Rojo, Andres Velez Jaramillo, Jhon Fredy Vega Maza, David Speed of sound data are reported for (carbon monoxide + ethane) and (carbon monoxide + propane) mixtures in the gas region at mole fractions of carbon monoxide of 0.25, 0.5 and 0.75 in the temperature range from 273.15 K to 350 K for mixtures containing ethane, and compositions xCO = 0.5 and 0.75 at T = (260 to 350) K for mixtures with propane. Measurements are performed by means of a spherical acoustic resonator with an expanded relative uncertainty (k = 2) better than 250 parts in 106. Experimental data are fitted to a virial type equation, obtaining standard deviations within the uncertainty of the measurements, and the adiabatic coefficient as perfect gas is derived from this fitting. Finally, all these data are compared to GERG-2008 and AGA92-DC equations of state, which are used as reference in the gas industry. 2024-12-19T12:34:08Z 2024-12-19T12:34:08Z 2024-12-19T12:34:08Z 2024 info:eu-repo/semantics/article The Journal of Chemical Thermodynamics, mayo 2024, vol. 192, 107260 0021-9614 https://uvadoc.uva.es/handle/10324/72893 10.1016/j.jct.2024.107260 107260 The Journal of Chemical Thermodynamics 192 eng https://www.sciencedirect.com/science/article/pii/S0021961424000132 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2024 The Author(s) Atribución 4.0 Internacional Elsevier
