摘要:
AbstractThis work considers the importance of vapor‐phase nonideal mixing in high‐pressure equilibrium and rate‐process calculations. New techniques are presented for calculating vapor‐phase fugacity coefficients in nonideal mixtures.The equilibrium properties of gaseous mixtures are represented by a virial equation of state which is adequate for the vast majority of chemical engineering problems. Techniques based on an extension of the corresponding‐states theory are given for estimating the various coefficients appearing in the equation of state; these estimates appear to be reliable for a large variety of nonpolar or weakly polar systems. Techniques based on the theory of intermolecular forces are also presented for polar systems and for a limited class of mixtures containing hydrogen‐bonding components. The proposed methods of calculation are illustrated by a large variety of problems occurring in common chemical engineering calculations, and it is shown that failure to correct for vapor‐phase nonideal mixing can, in some cases, lead to very

摘要:
AbstractValues of equilibrium composition for the hydration of ethylene to form ethanol have been calculated for a series of elevated pressures and temperatures by using equilibrium data available from previous low‐pressure studies. To obtain satisfactory agreement between these values and those measured experimentally, it is essential (1) to take into account the formation of ethyl ether and (2) to use available vapor‐liquid equilibrium data for the binary ethanol‐water system at elevated temperatures, instead of the standard “mixture rules” often employed.Thermochemical data and low‐pressure equilibrium data for both the ethylene hydration and ether formation reactions are critically reviewed. Experimentally measured values for the equilibrium concentrations of ethanol and ether in the liquid phase at 221°C. and 273 atm., with dilute sulfuric acid used as catalyst in a lined rocking‐bomb reactor,

摘要:
AbstractThe derived thermodynamic properties of acetylene have been determined over a temperature range of 32 to 500°F. and up to pressures of 2,000 lb./sq. in. abs. The data were calculated from vapor pressure, volumetric, and heat‐capacity data by the use of rigorous thermodynamic relationships. The calculated data were found to be internally consistent. The enthalpy values are believed to be accurate within ±1.0 B.t.u./lb. and the entropy values to ±0.001 B.t.u./(lb.)(

摘要:
AbstractThis paper presents a review of the field of thermodynamics of irreversible processes. The three essential steps in the use of this form of thermodynamics are the calculation of the entropy production, the setting up of the linear phenomenological equations, and the use of the Onsager reciprocal relation. The most important applications are to the transport processes, especially to the coupling phenomena which occur when two or more such processes take place in the same system.

摘要:
AbstractAn improved method is presented for handling isomer groups in the calculation of chemical equilibria in complex hydrocarbon mixtures. The new method reduces the number of simulataneous equations involved and makes practical the rigorous calculation of any hydrocarbon system for which free‐energy data are available, no matter how comple

摘要:
AbstractAlthough a considerable amount of work has been done on the compressibility ofn‐hexane, it has been impossible until now to compare or evaluate the work of the various investigators. There has also been a serious lack of information in the region above the critical temperature. It is the purpose of this work to make an extensive study of temperatures of 240° to 300°C. and of pressures up to 225 atm. in order to provide the lacking information and to overlap with the work of other investigators so that a proper evaluation of their work may be m

摘要:
AbstractThis paper illustrates the application of the root‐locus method in the design of a control system for a theoretical stirred‐tank reactor. The merits of control by measuring reactor concentration or temperature were considered at both an unstable and stable steady state reactor condition. The modes of control studied were proportional, proportional‐integral, and proportional‐integr
