CASE ANALYSIS
Scenario
A pharmaceutical facility requires a sterile mixing vessel with Clean-in-Place (CIP) and Steam-in-Place (SIP) cycles, including temperature control of the vessel during SIP. The P&ID integrates WFI, product, steam, and transfer lines with flow and temperature instrumentation.
Key decisions
- Use a vertical vessel (vessel_v) as the sterile mixing vessel with top inlets for product, WFI, and steam.
- Implement a temperature control loop (TT/TIC) on the vessel modulating the steam control valve.
- Add a WFI flow control loop (FT/FIC) for CIP operations.
- Use diaphragm-actuated fail-closed control valves for WFI and steam to ensure sterile boundary and fail-safe isolation.
When to reuse this
Applicable to pharmaceutical, biotech, or food processing P&IDs where a single mixing vessel requires CIP/SIP and temperature-regulated steam heating.
