Q

(PFD)

A

Process flow diagrams
A process flow diagram differs from a block flow diagram in that the PFD is more detailed and
conveys more information, which only gives a general sense of flow information.

would mean that there are actually two units in place. They are either in parallel or it is a main unit with a backup.

56
Q

Tables for process flow diagrams

A 
Stream table (Flow summery table)
Equipment summary table
57
Q

Stream table (Flow summery table)

A

Provides information of the physical properties of each process and utility stream → temperature,
pressure, composition, etc.

58
Q

Equipment summary table

A

Provides information of the physical characteristics of each piece of equipment → type, size, dimensions, orientation, pressure, capacity, power, etc

59
Q

Provide a stream table that is easy to read! Characteristics:

A

 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
Q

Utility Stream Tables

A

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.

61
Q

pipe number, piping class or designations)
 Details of equipment, machines, pipes, valves (e.g. pipe reducers given in separate list if necessary)
 Symbols for PCE (Process Control Engineering) including letter codes, process variables and control
functions
 Characteristic data of drives (in separate lists if necessary)

62
Q

Piping and instrumentation diagrams (Additional information)

A
