Influences of design parameters on performance in batch-type inclined-plate thermal diffusion columns

With the consideration of the total expense nearly kept unchanged, the influences of inclined-angle, plate spacing and plate aspect ratio changes on the performance for separation of a binary mixture in batch-type inclined-plate thermal diffusion columns have been investigated. Considerable improvement in the performance is obtainable if operation is carried out by increasing plate aspect ratio, and/or properly increasing inclined-angle, and/or properly decreasing plate spacing. The temperature differences between hot and cold plates, needed for keeping the operation expanse unchanged, are also delineated.
