the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...

The Ornstein-Zernike equation is solved for the hard-sphere and square-well fluids using a diverse selection of closure relations; attraction range chosen to be $\lambda=1.5.$ In particular, both we mainly focus on solution based three-parameter version Verlet relation [Mol. Phys. \textbf{42}, 1291-1302 (1981)]. To find free parameters latter, an unconstrained optimization problem defined as co...
