Process Definition Diagram (PDD)

A Process Definition Diagram helps process technologists describe a process independently of scale and equipment. It is a form of State Task Network, describing the process as a sequence of tasks that are performed to transform starting materials into products.

In addition to the sequence of tasks, PDDs also capture information on:

  • Where process materials are introduced and/or removed from the process
  • The phases present throughout each task
  • Phase changes (e.g. dissolution, gas evolution, etc)

PDDs can be used to:

  • Facilitate communiction in multidisciplinary teams as an aid to scale-up or tech transfer
  • Compare and contrast process options as part of whole process design
  • Collate observational data for troubleshooting
  • To represent the baseline process as part of Whole Process Analysis
