| Abstract: | In this work, the effect of vapor load and initial feed concentrations on column efficiency and liquid hold‐up in a two‐ and three‐phase packed distillation column at total reflux was investigated. Results for the two investigated mixtures (n‐heptane, n‐hexane, water) and (ethyl acetate, 1‐butanol, water) reveal that column efficiency remains almost constant for the former mixture but changes significantly for the latter. Specific liquid hold‐up and water to organic‐phase volumetric ratio within the column affect the column efficiency due to variations in initial feed concentrations. Influence of vapor load on separation efficiency and specific liquid hold‐up is also studied. |
