Correlation Of Pressure Drop And Holdup In A Packed Distillation Column, Nello Del Gobbo

Theses

Reed and Fenske have proposed a relationship that correlates the variables of packing dimensions, operating conditions, and fluid properties involved in countercurrent flow through packed distillation columns. Pressure drop and holdup data, obtained by atmosphere is distillation in columns packed with wire helices, was applied to the correlation by Reed and Fenske with good results. At reduced pressures limited data indicated the possibility of variations in the correlation as a function of the molecular weight of the material distilled.

Cummins investigated the effect of reduced pressure and holdup in distillation for several liquids using protruded packing. An attempt to correlate …

Heat Transfer Coefficients In Nucleate Boiling, Gerald Burt Fefferman

Theses

The purpose of this study was to investigate some new approaches to the problem of correlating heat transfer coefficients in nucleate boiling, A survey of previous work done in this field reveals much inconsistency in recorded data relating the heat transfer coefficient to other properties of the observed system, but general agreement has been reached, however, concerning the important influence of the temperature difference between the heating element surface and the boiling liquid. As this temperature difference is increased, the surface coefficient of heat transfer rises until a critical point is reached, marking the end of nucleate boiling and the …

In the course of the investigation of the ternary system, vapor-liquid equilibria were determined for each of the three binary systems. The CCl₄-C₆H₆ system is well known and data are presented in the International …

Thermodynamic Properties Of Methyl Isobutyl Ketone, Lionel James Sirois

Theses

The thermodynamic properties of methyl isobutyl ketone (4-methy1-2-pentanone, hexone) have been determined for the saturated region from 32°F to the critical temperature, 569°F. Properties in the superheated region were determined for temperatures from 200°F to 2000°F and over a pressure range from 5 psia to 1000 psia. Enthalpies, entropies, and specific volumes are reported for both phases where applicable. The datum point for all calculations was zero enthalpy and entropy for a unit mass of saturated liquid at 32°F and 0.083 psia.

Pressure-volume-temperature relations were predicted using the equation of state of Martin and Hou.⁽⁶⁾ This equation of state …

Evaluation Of Heat Transfer Coefficients For Annular Spaces, Jacob Levine, Allan Mornenberg

Theses

The object of this thesis is to find the best approach for evaluating the heat transfer coefficients in annular spaces.

The system studied consisted of air in turbulent flow through steam heated annuli. Twelve pipe ratios were tested, with a pipe diameter ration range (D₂/D₁) of 7.0 to 1.3.

It WAS found, contrary to most literature, that at constant values of W/A μ, the heat transfer coefficient decreases as the standard equivalent diameter decreases (D_e=D₂-D₁). Because of this observation, the use of a Reynold’s number based on an equivalent diameter …

The Synthesis And Cyclization Of 5-Chloro-2, 3-Dichloroacetamidopyridine, Edward Aloysius Naiman

Theses

The acetylation of 5-chloropyridine-2,3-diamino with chloroacetyl-chloride to yield 5-chloropyridine-2,3-dichlo-roacetamide and the subsequent ring closure form 6-chloro-2-chloromethyl-3H-imidazo-(b)pyridine has been studied in detail. The method of experimentation utilized statistically designed mathematical experiments.

The yield of 5-chloropyridine-2,3-dichloroacetamido is dependent upon the excess of the reactants and temperature, while time is not a significant factor. An important contribution to the study was obtained by extracting the product with solvents and discovering that the ring closed material 6-chloro-2-chloromethyl-3H-imidazo-(b)pyridine yields in quantity during the diacetylation reaction.

The ring closure of 5-chloro-2,3-dichloroacetamidopyridine is markedly temperature dependent. Time has little effect on the reaction yield. The analysis of …

Enthalpies And Partial Molal Enthalpies For N-Butane-Nitrogen System, Charles Fisk Paddock

Theses

Enthalpies and partial molal enthalpies are presented for the nitrogen-n-butane system at 340°F. and at pressures from 200 to 10,000 psia. The enthalpies were calculated for the pure components and for five mixtures using a graphical residual method which is described by Van Ness.⁽¹⁾ This method makes use of the Redlich-Kwong equation of state⁽²⁾ to calculate approximate values which are then adjusted by graphical correction factors. This paper illustrates both the advantages and disadvantages of this method, the graphical residual method being advantageous only when the graphical contribution to the total result is relatively small. Calculated enthalpies of …

Fugacity Coefficients Of Gases In Binary Mixtures, David W. H. Roth

Theses

Fugacity coefficients of components in gaseous mixtures have been calculated by a method proposed by Joffe which is based on the use of generalized thermodynamic functions, and on Kay's rule for definition of the pseudocritical points of a gaseous mixture. The method should be applicable to compounds which can be correlated by the theory of corresponding states.

The method was tested by application to 255 experimental points comprised of four gaseous systems, and included Argon-Ethylene, Hydrogen - Nitrogen, Methane - Ethane, and Methane n Butane. Thermodynamic functions from two recent generalized correlations, that of Pitzer et al., and that of …

Particle-Liquid Flow In Vertical Tubes, Frederick John Rowe

Theses

It was the purpose of this investigation to develop an experimental Procedure which would allow the prediction of the variation of fraction void with varying liquid and solid rates from a minimum number of experiments carried out in simple apparatus. This procedure should allow prediction for both smooth and rough particles, and should be valid for several different shapes. The data collected can be plotted on a single chart showing the relation between fraction void, solids throughput, and liquid throughput for all vertical particle fluid systems. Such a method was suggested by Mertes and Rhodes1 in their work developing a …

Power Requirements For Agitation In Fully Baffled Vertical Cylinders, Leo Francis Ryan

Theses

The decrease in power number with increasing Reynolds number sought in this thesis was observed. However, the majority of the data is not an indication of this phenomenon. Only with a relatively high ratio of turbine diameter to vessel diameter could a power number fall-off be obtained. The power number fall-off thus appears to be dependent upon this ratio of turbine diameter to vessel diameter. When the power number fall-off was evidenced, a deep vortex existed despite the presence of full baffling, and large quantities of air were entrained by the liquid.

Even after applying pseudo corrections for both entrained …

Equilibrium And Reaction Rate Constants Of Esterification Of Nitrobenzoic Acids, John Nicholas Korzun

Theses

A determination of equilibrium constants and reaction kinetics for the esterification of ortho, meta, and para-nitrobenzoic acids with methanol and ethanol was performed. A search of past literature showed that the equilibrium constants for the above acids and alcohols had not been measured previously.

The equilibrium constants (Ke) obtained for ortho, meta, and para-nitrobenzoic acids using p-toluene sulfonic acid as catalyst and ethanol as the alcohol were 3.59, 4.56, and 2.91: respectively. Using methanol as the alcohol, the corresponding constants were 2.61: 2.65, and 1.92.

Hydrochloric acid was also studied as a reaction catalyst, but, a side reaction between catalyst …

Critical Masses Of Oralloy Cylinders With Multiple Reflectors Of Medium Z Elements, David P. Wood

Mechanical Engineering ETDs

Critical mass is influenced mainly by the density, concentration, and shape of the fissionable material, the degree of neutron moderation, and the type and thickness of reflector material. Most of these parameters have been explored in detail at the Pajarito Remote-Control Laboratory (1) and the present series of measurements has the purpose of investigating reflector materials in the middle of the periodic table for the more subtle influence of their resonance scattering structure.
