Book Description
This thesis comprises of two parts. The first part is the determination of vapor-liquid equilibrium data at atmospheric pressure and 55°C for the ternary system n-hexane-ethyl alcohol-benzene and for the three possible binary systems n-hexane-ethyl alcohol, n-hexane-benzene and ethyl alcohol-benzene which constituted the ternary system. A modified Gillespie equilibrium still is employed to conduct the investigation. The equilibrium data for the three binary systems and the ternary system appear to be consistent as shown from the thermodynamic consistency tests. The experimental results indicate that two binary systems, namely, n-hexane-ethyl alcohol and ethyl alcohol-benzene form azeotrope at 760 nm. Hg. and 55°C. The ternary system deviates considerably from ideal liquid phase behavior. However, no ternary azeotrope is found from the experiment. The second part presents a method for predicting binary vapor-liquid equilibrium data at various conditions if the equilibrium data for the system concerned are available over the complete concentration range at any one isothermal or isobaric condition. The proposed method is limited to nonazeotropic solutions.

Book Description
Vapor-Liquid Equilibrium, Second Edition covers the theoretical principles and methods of calculation of equilibrium conditions from various experimental data and the elements of measuring technique, as well as the instruments for the direct determination of the equilibrium compositions of the liquid and vapor phases of the system. The book discusses the relations necessary for the thermodynamic treatment of the equilibrium between the liquid and vapor phase of a system; the concept of an ideal solution and auxiliary thermodynamic functions; and the activity and the activity coefficient. The text also describes vapor-liquid equilibrium in real systems (electrolytes and non-electrolytes) and in systems whose components (i.e. temperature, pressure, and composition of phases) mutually react according to several stoichiometric equations. The criteria of purity of substances and the methods of measuring temperature; low, medium, and high pressures; the pressures of the saturated vapors at given temperatures; and the boiling points at given pressures used in laboratory work in the field of vapor-liquid equilibrium are considered. The book also tackles the methods for the direct determination of equilibrium data (distillation, circulation, static, dew and bubble point, and flow methods). The text concludes with a review of the literature on the systems whose vapor-liquid equilibrium data had been measured and reported to the beginning of 1954. Workers in the chemical industry who deal with problems of distillation and rectification will find the book useful.

Book Description
Working Guide to Vapor-Liquid Phase Equilibria Calculations offers a practical guide for calculations of vapor-phase equilibria. The book begins by introducing basic concepts such as vapor pressure, vapor pressure charts, equilibrium ratios, and flash calculations. It then presents methods for predicting the equilibrium ratios of hydrocarbon mixtures: Wilson's correlation, Standing's correlation, convergence pressure method, and Whitson and Torp correlation. The book describes techniques to determine equilibrium ratios of the plus fraction, including Campbell's method, Winn's method, and Katz's method. The remaining chapters cover the solution of phase equilibrium problems in reservoir and process engineering; developments in the field of empirical cubic equations of state (EOS) and their applications in petroleum engineering; and the splitting of the plus fraction for EOS calculations. Includes explanations of formulas Step by step calculations Provides examples and solutions
