具有垂直隔板的蒸馏塔可以将进料混合物分离成3或4个纯馏分。与其他塔布置相比，它们的投资成本和能耗更低。生产柱显示出良好的结果并且易于控制。常规蒸馏塔在塔的顶部和底部仅产生2个纯产物流。副产品被轻质或重质组分污染，这取决于侧流在精馏或汽提段中的位置。通过使用具有垂直隔板的蒸馏塔，该缺点被搁置。内部分隔壁防止液体和蒸气在塔的中心部分中横向混合，在那里形成分离的进料和出口部分。在垂直隔板的存在下，在单个蒸馏步骤中可以获得3或4个纯馏分。这在分离热敏组分时是特别有利的。由于良好的热力学性质，能耗比其他蒸馏装置低20 - 35%。控制性能与常规蒸馏塔相似或更好。
Distillation columns with vertical partitions can separate a feed mixture into 3 or 4 pure fractions. Compared to other column arrangements, their investment costs and energy consumption are lower. Production columns show good results and are easily controlled. Conventional distillation columns produce only 2 pure product streams at the top and at the bottom of the column. Side products are contaminated by light or heavy components, depending on the location of the side stream in the rectifying or stripping section. This disadvantage is set aside by using a distillation column with a vertical partition. The internal separation wall prevents lateral mixing of liquid and vapour in the central part of the column, forming there separate feed and outlet sections. In the presence of a vertical partition, 3 or 4 pure fractions can be obtained in a single distillation step. This is particularly advantageous when heat sensitive components are to be separated. On account of good thermodynamic properties, the energy consumption is 20 to 35% lower than that of other distillation arrangements. The control behaviour is similar or better than that of conventional distillation columns.
