The objectives of the present part of the project were 1) to design, construct, and operate Von Halle-Jury thermal diffusion columns for the separation of a convenient salt mixture, 2) to compare the heights of a transfer unit and the equilibrium coefficients for the separations with estimates from Soret (single thermal diffusion stage) data, 3) to determine the effect of certain operating variables, such as length, width, and temperature difference, on these separation parameters, and 4) to develop a design procedure for iv commercial separation processes , including columns in a cascade.

Summary: By the use of photographic techniques, the absorption rates of single CO2 bubbles suspended in downward flowing aqueous monoethanolamine (MEA) solutions were determined for various MEA and CO2 liquid concentrations. It was found that a linear correlation of the experimental data could be obtained by plotting the mass of the bubble to the one-third power versus absorption time. Such a correlation indicates that the absorption rate per unit area is constant. The absorption rates were found to increase with MEA concentration and to decrease with total absorbed CO2 concentration (that physically absorbed and chemically combined). However, …
