Abstract
Characteristics of cryogenic distillation columns having small inner diameters (1 and 2 cm) were studied by separating N{sub 2} and Ar. The columns were packed with Dixon Rings whose sizes were 1.5, 3.0, and 6.0 mm. No significant effect of the vapor velocity within the column on the HETP was observed for the sizes of the packings and the column diameters tested. For both of the columns, the 1.5 mm and 3 mm Dixon Rings gave almost the same HETP values (5.5 cm), whereas larger HETP values (8 {approx} 12 cm) were obtained for the 6 mm Dixon Rings. A discrepancy between the calculated and experimental values of the Ar concentration at the middle of the column was observed in cases where the vapor velocity was small; this tendency was enhanced by the decrease in the sizes of the packings. The 3 mm Dixon Rings presented the most excellent separation characteristics for both of the columns in terms of the HETP and the suitability of predicting column behavior by the stage model.
