Diagram of a typical industrial distillation tower Industrial towers use reflux to achieve a more complete separation of products. Reflux refers to the portion of the condensed overhead liquid product from a distillation or fractionation tower that is returned to the upper part of the tower as shown in the schematic diagram of a typical, large ...
Figure 5: Section of fractionating tower of Figure 4 showing detail of a pair of trays with bubble caps Figure 6: Entire view of a Distillation Column In industrial uses, sometimes a packing material is used in the column instead of trays, especially when low pressure drops across the column are required, as when operating under vacuum .
The typical McCabe–Thiele diagram in Figure 1 uses a q-line representing a partially vaporized feed. Example q-line slopes are presented in Figure 2. The number of steps between the operating lines and the equilibrium line represents the number of theoretical plates (or equilibrium stages) required for the distillation. For the binary ...
The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser. Additional heat is removed from the distillation column by a pumparound system as shown in the diagram below.
Large-scale industrial towers use reflux to achieve a more complete separation of products. [5] Reflux refers to the portion of the condensed overhead liquid product from a distillation or fractionation tower that is returned to the upper part of the tower as shown in the schematic diagram of a typical, large-scale industrial distillation tower ...
English: Cross-sectional diagram of operating industrial scale Binary Distillation Tower with trays with bubble caps, separating a feed stream into one distillate and one bottoms fractions (description taken from Tray_Distillation_Tower.PNG by H_Padleckas).
Image 5: Cross-sectional diagram of a binary fractional distillation tower with bubble-cap trays. (See theoretical plate for enlarged tray image.) Distillation towers (such as in images 3 and 4) use various vapor and liquid contacting methods to provide the required number of equilibrium stages.
