Typical Crude Distillation with Steam Strippers Fig. 5 a typical crude distillation unit with steam strippers for its side draws products, namely kerosene and gas oil. Cut Points. Using a crude TBP curve, cut points are defined as the temperatures that represent the limits of a distillate fraction, as illustrated in Figure 4.11. For example, for kerosene, fraction Ta represents the lower cut point, and Tb represents the upper cut point in Figure 4.11.

that the preflash/prefractionation arrangement of distillation units is not as energy efficient as the conventional design in the absence of a vacuum unit. The same was found for a newly proposed stripping-type design. The use of a vacuum column, however, has many implications on energy consumption, which alters these conclusions.  · Vacuum Distillation Procedure. A vacuum distillation apparatus is shown in Figure 5.50, using a simple distillation setup. A fraction distillation can also be used. It is assumed that readers have previously performed a simple distillation under atmospheric pressure, so in this section are described differences between atmospheric and reduced pressure distillations.
