ABSTRACT


This work investigated the plate spacing effect on binary mixture separation removal rate in a countercurrent-flow Frazier scheme with N flat-plate thermal diffusion columns of the same size and with fixed total expense. The equations for estimating optimal plate spacing and the corresponding maximum removal rate are developed. Considerable improvement in performance is obtainable when thermal diffusion columns with optimal plate spacing are employed for operation. The fact that the countercurrent-flow operation is more effective than the cocurrent-flow operation in a Frazier scheme, is also confirmed.
