Computation of vapour—liquid equilibrium in N2 + CO2 + CH4 system by a general cubic equation of state

Solid - Gas Equilibrium in Systems Containing Aromatic Compounds and Supercritical Carbon Dioxide

“…In this work, the GEOS parameters m and α c for carbon dioxide and for all aromatic compounds were obtained by matching points on the saturation curve together with the corresponding liquid density [7].…”

Modeling of the thermodynamic properties of the methylamine/water refrigerant mixture

“…For mixtures composed of self and cross-associating components, the monomer fractions X i for all associating compounds can be simultaneously evaluated iteratively from the system of equations (6) and considering the above given assumptions. 59,61,62 For the binary methylamine/water mixture investigated in this paper, X 1 and X 2 are evaluated by solving the equation system: 61,62 ( )…”

“…Applying the Barker-Henderson perturbation theory to a reference hard-chain fluid, a valuable variant of the original SAFT model [52][53] is obtained and applied to correlate asymmetric, highly non-ideal, and associating fluids. [54][55][56][57][58][59][60][61][62] The general cubic equation of state GEOS considered in the present paper is a semi-empirical approach. [63][64][65][66][67] GEOS is a fourcoefficient cubic EOS that permits the critical compressibility factor adjustment, ZC, instead of the prediction of a universal value.…”

“…Thus, a careful chose should be considered. The reduced association Helmholtz free energy of a mixture can be written as a mole fraction weighted linear combination of the free energies of the pure components:[59][60][61][62] ln 2 2…”
