Stripping absorption factor chart

Stripping Factor or Absorption Factor Chart for Stripping... 

In this chapter we will discuss single theoretical stage Bubble-Point and Dew Point calculations and give examples as to how these can be used in our work. Then weTl discuss the use of the Absorption Factor and Stripping Factor chart, which can be used to design distillation towers. In order to use this chart in that way it is necessary to consider a distillation tower as two separate towers. The top of the tower is considered an absorber. The chart is then used in a different way to design the lower part of the distillation tower as a stripper. 

The Absorption factor or Stripping factor chart, as it is sometimes known, is shown in Fig. 50.5. It provides simple calculation methods for hydrocarbons when considering either an Absorber tower or a Stripper tower in hydrocarbon service, but for combination Absorber-Stripper towers the calculation procedures become iterative and a lot more complex. So for a combination Absorber-Stripper tower it is best not to attempt to use this chart. It is actually better to resort to a computer simulation. In fact, as a point of historical interest, Norman tells me that it was when the idea of combined Absorber-Stripper towers was first invented that brought about the use of computer simulations so as to handle all the intricate and cumbersome calculations needed to design them.
