Abstract
An experimental adsorption and desorption study was carried out using propane-propylene gas mixtures adsorbed onto 13X molecular sieves in order to obtain a better understanding of a variable-temperature stepwise desorption (VTSD) method that has been found to have potential for industrial separations. The experimental conditions used were based on estimates of possible industrial importance. Both desorption rates and desorption equilibrium data were obtained at one atmosphere with no dilution gases, in small U-tube columns (0.012 m diameter). The desorption rates appeared to be relatively rapid and not an important factor in pilot-scale desorption in comparison with heat transfer rates. A computational method has been developed in order to calculate the composition and amounts of gases that are desorbed during variable-temperature stepwise desorption. The computed predictions ofa pilot-scale system, based on equilibrium data from small scale column experiments, were compared with pilot-scale (0.04 m diameter × 1.8 m length) experimental results and were found to provide reasonable approximations.
