Solubility of methane in heavy normal paraffins at temperatures from 323 to 423 K and pressures to 10. 7 MPa
- Oklahoma State Univ., Stillwater, OK (United States). School of Chemical Engineering
Solubility data are presented for methane in four heavy normal paraffins at temperatures from 323 to 423 K and pressures up to 10.7 MPa. The paraffins studied are eicosane (n-C[sub 20]), octacosane(n-C[sub 28]), hexatriacontane (n-C[sub 36]), and tetratetracontane (n-C[sub 44]). The data obtained for the solubility of methane in n-C[sub 20], n-C[sub 28], and n-C[sub 36] are in good agreement with the earlier measurements of Chao and co-workers. The new data can be described with RMS errors of about 0.001 in mole fraction by the Soave-Redlich-Kwong (SRK) or Peng-Robinson (PR) equation of state when two interaction parameters per isotherm are used. Henry's constants and partial molar volumes at infinite dilution for methane have also been evaluated from the data.
