Abstract

The performances of a novel rapid pressure swing adsorption system for continuous production of ˜ 90% O2 from a compressed air feed were experimentally studied using two different samples of pelletized LiLSX zeolite. Bed size factor (BSF) and O2 recovery (R) were compared as functions of total process cycle times. The optimum performance by the samples differed substantially—one exhibiting ˜ 30% smaller BSF and ˜ 6% higher R than the other, even though the adsorption isotherms and column dynamics for the pure gases were nearly identical. Column pressure drop during the desorption step was the cause.
