The request
“Draw a sterile mixing-vessel P&ID with WFI and product tanks, a mixing vessel, transfer pump, clean steam generator, product isolation valve, and temperature and flow control loops.”
Then tryAdd a sterile vent filter to the mixing vessel.Change the product transfer pump to a diaphragm pump.
What is in this drawing
Read the decisions behind it.
01
Use a vertical vessel (vessel_v) as the sterile mixing vessel with top inlets for product, WFI, and steam.
02
Implement a temperature control loop (TT/TIC) on the vessel modulating the steam control valve.
03
Add a WFI flow control loop (FT/FIC) for CIP operations.
04
Use diaphragm-actuated fail-closed control valves for WFI and steam to ensure sterile boundary and fail-safe isolation.
Applicable to pharmaceutical, biotech, or food processing P&IDs where a single mixing vessel requires CIP/SIP and temperature-regulated steam heating.
