Polyethylene is the most popular man-made polymer. One way of making polyethylene consists in producing the polymer in the form of grains suspended by a gas flow of olefins (monomers), nitrogen and other hydrocarbons (alkanes). Industrials want to know the solubility of the monomers in the polyethylene grains, as the rate of the polymerization reaction is a direct function of this solubility. T...
A framework to self-consistently combine a classical equation of state (EoS) and molecular force field model polymers polymer mixtures is presented. The statistical associating fluid theory (SAFT- γ Mie) used correlate the thermophysical properties oligomers generate robust transferrable coarse-grained (CG) parameters which can be both in particle based simulations equations calculations. Examp...
in this work, we consider each normal alkane as a hypothetical mixtureof methyland methylene groups, in which the interaction potential of each pair is assumed to be the average effective pair potential. then, the lir equation of state (eos) is extended for such a hypothetical mixture. also, three basic compounds, namely, propane, n-butane and cyclohexane, are used to obtain the contribution of...
a mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der waals mixing rule at low densities. the effectiveness of the mixing rule for the size and energy parameters of lennard-jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. the results of calculation are compared with the molecular dynami...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
utopia has, for four centuries, accompanied that hope of progress and that striving for betterment. it now straggles against a widespread sense that this has been an illusion, or an impossible dream. the utopian idea can never entirely disappear, but utopia as a form of the social imagination has clearly weakened. if it cannot instill its vision in the public consciousness, the consequences...
alkanolamine solutions such as 2-amino-2-methyl-1-propanol (amp) are widely used in chemical industries for the removal of acid gases such as co2 and h2s. in this work, the density of co2, amp, water, and amp solutions using the goharshadi–morsali–abbaspour equation of state “gma eos” in the extended 50-degree range of temperatures (313.06-362.65 k) and pressures (0.5-40 mpa) was calculated. th...
solubility of high molecular weight n-paraffins in supercritical carbon dioxide has been a matter of interest to many researchers. however, not sufficient solubility experimental data are available although the methods by which the experimental data are obtained have many varieties. utilizing cubic equations of state is an effective method for solubility prediction of n-paraffins in supercritic...
