Temperature Dependence of Isobaric T.D. Factor by Column

Abstract

Temperature dependence of thermal diffusion factor, α_T, of N₂–CO (1 : 1) gas mixture can be assessed from the measurement of the equilibrium steady state separation factor, q_e as a function or pressure at 350.1, 378.5 and 413.5 K by a concentric tube type hot wall thermal diffiusion column already calibrated by a gas mixture of known and reliable α_T data. Too much attention to the column geometry is, thus, avoided through the use of the existing theoretical formulations for column in calculating α_T.
