The Separation Efficiency of Continuous Thermal Diffusion Columns with a Sidestream Withdrawn at the Feed Position

本文導出適用於進料位置具側流之連續熱擴散塔全濃度範圍操作下之分離公式。由於側流具有氣提之功用，故能?有效地提高分離效果，且此效果隨著側流強度之增加而提高。當進料自適當位置引入時，可得最大分離度，最大塔頂產品濃度或是最小塔底產品濃度。
The equation of separation applicable to the whole concentration range in a continuous thermal diffusion column with a sidestream withdrawn at the feed position has been derived. Since the sidestream acts as scrubber, it may effectively improve the separation. Corsiderable improvements are obtained as the strength of the sidestream increases. It is shown that maximum degree of separation, maximum concentration of top procuct or minimum concentration of bottom product is reached when the feed is introduced from the best position of the column.
