1. Introduction to Chemical Process Design

2. Types of Process Diagrams
The most effective way of communicating information about a chemical process is through the use of process diagrams
Block Flow Process Diagram
Block Flow Plant Diagram (For Large/Complex Plant)
Process Flow Diagram (PFD)
Develop corresponding Flow & Equipment Table
Piping and Instrumentation Diagram (P&ID)

10. Process Flow Diagram (PFD) Characteristics

11. Information Provided by the PFD
Process Topology
Location and interaction between streams & equipment
Stream Information
Represented by lines and identified by a number
Operating conditions included (e.g. T, P, flow rates)
Two stream types: Process streams & Utility streams
Table Summary Provided in support of PFD
Equipment Information
Represented symbolically by icons and identified by a number
Table Summary provided in support of PFD to provide necessary information to estimate costs

19. CHE 4181/4182 PFD Requirements
All Equipment Labels should follow the XX-YZZ convention outlined in Table 1.2
The PFD should have labels at the top indicating equipment labels and description as shown in Figure 1.5
The utility streams should be labeled appropriately on the PFD
No instrumentation or controls should be included on PFD
The PFD should be presented in landscape format and be large enough to clearly read
Stream and Equipment tables similar to those presented in Tables 1.5 and 1.7 should accompany the PFD in separate pages
