The global phase behavior (i.e., vapor-liquid and fluid-solid equilibria) of rigid linear Lennard-Jones (LJ) chain molecules is studied. The phase diagrams for three-center and five-center rigid model molecules are obtained by computer simulation. The segment-segment bond lengths are L = sigma, so that models of tangent monomers are considered in this study. The vapor-liquid equilibrium conditi...

In spite of the increasing levels greenhouse gases in atmosphere, and their impact on environment, demand for natural/biogas will increase significantly coming few decades. To cover this demand, global energy industry is continuously exploiting sour gas reserves located around world. Nonetheless, has to be sweetened before practical utilization natural or biogas. The cryogenic separation techno...

Force fields based on a Lennard-Jones (LJ) 12-6 plus point charge functional form are developed for acetone and chloroform specifically to reproduce the minimum pressure azeotropy found experimentally in this system. Point charges are determined from a CHELPG population analysis performed on an acetone-chloroform dimer. The required electrostatic surface for this dimer is determined from ab ini...
