Design of a Hybrid Configuration

FIGURE 9.12 (a) A possible l brid configuration, (b) The CSs for tfie hybrid system [1]. 

We have shown in this book that any distillation configuration, no matter how complex, can be modeled using CPMs. The example shown here is an extension of this work. While previous Chapters 5 7 focused on distillation only, we include the addition of a membrane unit connected to CSs. 

Regardless of the configuration of the hybrid process, the objective is to meet the separation requirements. By specifying the feed and product compositions, the product flows can be determined for a set feed flowrate. It is assumed that the feed rate is 100 mol/s. 

APPLICATION OF COLUMN PROFILE MAPS TO ALTERNATIVE SEPARATION PROCESSES 

It can be seen that once an r i-value is set, all the values in Table 9.1 are known. However, setting r i alone does not fuUy specify the entire hybrid system. Another degree of freedom is the amount of liquid that enters the membrane unit from the end of CSi. Only liquid is drawn off since a pervaporation membrane is incorporated. The split ratio.
