Process unit
A process unit is an organizational unit that is physically made up of equipments and control modules. The process unit combines all necessary physical processing and control equipment required to perform the processing activities. The definition of a process unit requires knowledge of the major processing activities, as well as the equipment capabilities and the tracking requirements. The following guidelines apply:
- One or more major processing activities, such as reaction, crystallization and storage, may take place in a process unit.
- Process units should be defined such that they operate relatively independently of each other.
- A process unit is presumed to operate on only one batch at a time in the case of batch processing.
- In terms of tracking, there must be well defined material transactions across the unit borders.
