Figure 11.16 The thermally coupled indirect sequence for crude oil distillation.

The majority of atmospheric crude oil distillation columns follow the configuration shown in Figure 11.17, which is basically the partially thermally coupled indirect sequence. 

Consider now ways in which the best arrangement of a distillation sequence can be determined more systematically. Given the possibilities for changing the sequence of simple columns or the introduction of prefractionators, side-strippers, side-rectifiers and fully thermally coupled arrangements, the problem is complex with many structural options. The problem can be addressed using the optimization of a superstructure. As discussed in Chapter 1, this approach starts by setting up a grand flowsheet in which all structural features for an optimal solution are embedded.

Three thermally coupled schemes have been particularly analyzed. Two of them are fairly similar and make use of a main column and a side column. One can use a side extraction in the vapor phase from the first column and feed it to a side rectifier that purifies the intermediate component. The reboiler of the side column is eliminated by recycling the bottom stream, in the liquid phase, to the first column. The arrangement is known as a thermally coupled distillation system with a side rectifier (TCDS-SR), and its structure is shown in Figure la. If the side extraction from the first column is carried out in the...
