The separation theory of horizontal thermal diffusion columns with external refluxes, which was developed by Halle and Jury, has been derived by use of an orthogonal expansion technique. Considerable improvement is obtained when the refluxes and feed position are carefully chosen. The present formulation can be extended to other conjugated Graetz problems in continuous‐contact countercurrent separation processes with refluxes at both ends.
