Tables for process flow diagrams
```
Stream table (Flow summery table)
Equipment summary table
```
57
Stream table (Flow summery table)
Provides information of the physical properties of each process and utility stream → temperature,
pressure, composition, etc.
58
Equipment summary table
Provides information of the physical characteristics of each piece of equipment → type, size, dimensions, orientation, pressure, capacity, power, etc
59
Provide a stream table that is easy to read! Characteristics:
Do not list components in alphabetical order → reactants first, followed by products
Choose appropriate units (especially for mass and molar flow rate) → 1 to 4 digits
Avoid scientific notation → revise tables created e.g. by ASPEN (9.9999E-8 → 0)
Don´t use more than 4 significant figures (even if available by ASPEN etc.)
Write right-aligned table
60
Utility Stream Tables
Practical: Use a separate utility stream table with only information required is shown → no
reactants, products etc. → Table is much faster and easier to read.

Once it has been decided that the design is sufficiently complete to issue for construction, the
design will be frozen, which means that no significant changes will be allowed.
