中文摘要 | 本文旨在探討逆流型佛雷茲熱擴散塔組中板之長寬比對分離度與產率之影響。文中並推導出獲得最大分離度與最大產率之最佳長寬比的計算公式。研究結果證實,在最佳長寬比操作下,確實顯著提高熱擴散效率,而且逆流型遠比順流型為佳。 |
英文摘要 | The effects of plate aspect ratio on the degree of separation and production rate in a countercurrent-flow Frazier scheme with N flat-plate thermal-diffusion columns of same size and with plate surface area fixed, have been investigated. The equations for estimating optimum plate aspect ratio for maximum separation and maximum production rate have been derived. Considerable improvement in performance is obtainable when the thermal diffusion columns with optimum plate aspect ratio are employed for operation. The fact that countercurrent-flow operation is more effective than cocurrent-flow operation in a Frazier scheme, is also cinfirmed. |
