    摘要: Development of the separation equation in a classical Clusius‐Dickel column with sidestream operations for the heavy water enrichment has been accomplished theoretically. Performance of the modified Clusius‐Dickel column with sidestream operations and its corresponding maximum separation was determined with the sidestream flow‐rate ratio at the feed position and top flow‐rate fraction as parameters. The effect of the sidestream operation of a modified Clusius‐Dickel column on separation efficiencies for the H2O‐HDO‐D2O system has been investigated theoretically and experimentally. The theoretical predictions were in good agreement with the experimental results. The theoretical results indicated that the maximum separation efficiency increases with the side stream flow‐rate fraction but decreases with feed flow rate and are represented graphically and compared with that in a classical Clusius‐Dickel column. Considerable improvement in the device performance is obtained by employing a modified Clusius‐Dickel column under sidestream operations and flow‐rate fraction variations, instead of using a classical Clusius‐Dickel column.
