Preparation of yttrium and rare-earth metals by metallothermic reduction

Creator:: Block, Frank Elmer
Abstract:: An investigation was made of various methods for the preparation of yttrium or rare-earth metals by metallothermic reduction. Particular emphasis was placed on the use of high-purity chloride salts as intermediates. Methods were stressed which appeared adaptable to production of high-purity, ductile metal on a plant scale. Reactions were chosen...

Mass transfer in a multiple stage cross-current packed column

Creator:: Bayan, Ghawamedin
Abstract:: A cascade crosscurrent column, packed with Pall rings, was employed for ammonia absorption from ammonia-rich air phase by contacting with water. Absorption efficiency was presented as the percentage of NH₃ removed as well as the volume of a transfer unit. A review of the literature concerning the theoretical and experimental...

Dynamics behavior of a cascade, cross-flow, packed column

Creator:: Golshani, Aboutaleb
Abstract:: The dynamics of a cross-flow, packed tower were investigated as a new alternative for gas-liquid contacting. At the present time there are two methods of gas-liquid contact, co-flow, and counter-flow, both having known limitations. This investigation studies cross-flow contact in an effort to eliminate the lower limits of gas-liquid flow...

The effect of concentration on diffusion coefficients in binary systems

Creator:: Prabhu, Kumbla Narasimha Srinivas
Abstract:: Diffusion coefficients were determined for the chloroform-air system at 50°C and for the methanol-air system at 55°C by the Arnold cell technique. The effect of concentration was studied by varying the concentration of the gas stream passing across the top of the Arnold cell. The chloroform-air system exhibited a strong...

Computer model : mass transfer from single rising gas bubbles in water

Creator:: Sing, Gerald Lum
Abstract:: Mass transfer from single rising gas bubbles is generally studied by taking motion pictures of the rising bubbles and analyzing the film for the instantaneous mass transfer coefficient. In this study, a different approach was taken for the analysis of mass transfer. This analysis solved the simultaneous differential equations describing...
