[ 1 ] - Design of Optimal Process Flowsheet for Fractional Crystallization Separation Process
A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...
[ 2 ] - High Pressure Phase Equilibrium of (Solvent + Salt + CO2) Systems by the Extended Peng-Robinson Equation of State
An extended Peng-Robinson equation of state (EPR-EOS) is used to model the vapor-liquid equilibrium (VLE) in systems containing (water + NaCl + CO2), (water + methanol + NaCl + CO2), (water + Na2SO4 + CO2) and (water + NH4Cl + CO2). The binary and ternary interaction parameters between salt and solvent are adjusted...
[ 3 ] - VLE Predictions of Strongly Non-Ideal Binary Mixtures by Modifying Van Der Waals and Orbey-Sandler Mixing Rules
By proposing a predictive method with no adjustable parameter and by using infinite dilution activity coefficients of components in binary mixtures obtained from UNIFAC model, the binary interaction parameters (k12) in van der Waals mixing rule (vdWMR) and Orbey-Sandler mixing rule (OSMR) have been evaluated. The predicted binary interaction parameters are used in Peng-Robinson-S...
