2. Use of BACK To Modify SAFT in Order To Enable Density and Phase Equilibrium Calculations Connected to Gas-Extraction Processes

摘要: Statistical associating fluid theory (SAFT) has been extended to mixtures at temperatures slightly above the critical temperature of one compounds as often encountered in gas-extraction processes. The proposed extension is based on contact values average correlation function for a pair mixture hard convex bodies different types by Boublik and allows described BACK equation state with nonassociating sphere chains from original SAFT. supercritical solvent modeled body, allowing an accurate description near-critical region, while all other are chains, utilizing benefits can be added any existing SAFT software, quickly. Additionally, two-parameter mixing rules that defined segment basis instead molecular or system like SAFT, promising higher predictive capability sy...
