Development and Testing of a Rotary Disc Pulser for Pulse Column Application

摘要

Air pulse column contactors are a favored method of conducting radiochemical liquid-liquid separations processes. They have no moving parts and are easily operated from behind thick shielding. A ruggedly constructed more reliable air pulsing device was developed and its operation mathematically characterized in this study. Additionally, a correlation for the column perforated nozzle plate discharge coefficient was developed. Rigorous mass, momentum, and energy balances were solved using a computer software code entitled ''Advanced Continuous Simulation Language.'' Experimental data from a 2-inch diameter glass column equipped with the prototypical air pulser showed that column pulse amplitudes could be predicted within 10% for the conditions studied and within 5% for normal column operating conditions. 17 refs., 45 figs., 15 tabs.
