Synthesis of the PFD from the Generic BFD

2. It is a common human trait to resist change more strongly as more effort is expended on a task, design, or product. We describe this as not wanting to abandon our “investment” in the activity.

3. Information Needs and Sources
Interactions with other engineers and scientists.
Reaction kinetics data.-main and by products, catalysts,patents. Without kinetics data a prelim PFD and cost analysis can be done.(~.10kg product/kg catalyst per hour. Ea kJ/mol)
Physical property data-material and energy balances

4. Reactor Section Phase of the reacton Temperature and pressure ranges
Controlled by kinetics or equilibrium
Need a solid catalyst or is it homogeneous
Exothermic or endothermic (magnitude)
Side reactions and selectivity
Single pass conversion.
Reactor feed outside the explosive limits fro gas-phase oxidations

5. General guidelines for choosing separation operations
Table Guidelines for choosing separation units.
Table Guidelines for sequencing separation units.

6. Sequencing Distillation Columns

Azeotropes- figure 10.4

7. Feed preparation Heat exchangers Pumps Compressors
Exothermic reaction feed temperatures need to be high in order to prevent reactor runaway due to buildup of unreacted material and cause a severe temperature spike.

8. Recycle Section
Should be at same conditions of feed when combined.

9. Environmental Control Section
Minimize or eliminate

10. Major process control loops
Significant design improvements can occur through developing major control loops.
They provide focal points for optimizing the process.
