High Pressure Vapor-liquid Equilibria in the System Acetone-methanol-water


Book Description

"In the field of synthetic liquid fuels and organic chemicals there is considerable industrial interest in Fischer-Tropsch-type processes for the production of liquid hydrocarbons and various organic chemicals as by-products. Processes developed primarily for the production of oxygenated organic chemicals by partial oxidation of paraffin hydrocarbons are also in commercial operation. For both processes, recovery and purification of the product constituents by fractional distillation constitute a major problem. Of primary importance to solutions of the problem are the availability of reliable vapor-liquid equilibrium data on the various systems encountered. The need for suitable data is increased by the fact that practically all existing vapor-liquid equilibrium data are for atmospheric pressure only, whereas actual distillation operations are most frequently conducted at pressure above one atmosphere because of favorable economics, design, operations, and control requirements. It is obvious that reliable data at pressure other than one atmosphere and in particular, superatmospheric data are needed. More fundamentally important however, is the need for complete and extended data to evaluate and test the applicability of proposed correlations of the vapor-liquid data. Such extension and correlation involve the change of vapor-liquid equilibria with temperature or pressure, the determination of these data with a minimum of experimental effort, and the extension of binary data into reliable ternary data. Of the numerous oxygenated components produced by the aforementioned processes, acetone, methanol, and water constitute the major portion of the crude products. Binary and ternary systems containing these components have been evaluated and the results reported herein"--Leaves iii-iv



















Vapor-liquid Equilibrium Data at High Pressure


Book Description

High pressure vapor-liquid equilibrium data are important when very pure compounds are to be prepared, and they are also needed for high pressure liquid or supercritical chromatography. This volume is a compilation of high pressure vapor-liquid equilibrium data for 700 binary system, processed and plotted by computer for ready inspection of the whole spectrum. The information given for each system comprises: the components' names, chemical formulae, cited literature, and critical temperature, critical pressures, acentric factors of the components, optimized values of the parameters for the Peng-Robinson equations, the errors, and phase diagrams for visual comparison of the experimental data and calculated values. An alphabetical index by system name is included in the book which will be a useful reference for chemical engineers, research chemists, and graduate students who are interested in the chemical process industry.
