PFD Review
Review of the PFD is an important part of the design process whether the flow sheet is newly generated or altered from existing designs. The process of PFD is usually done in committee consisting of the design team and relevant unbiased consultants.
PFD Review Procedures
1. PFD Printout. Display the PFD on a wall such that it is visible to all members of the review committee. Allow enough space between equipment for addition and notes. 2. Walkthrough. Introduce the PFD, describing all streams and process operations. 3. Questions. The review group should challenge the design team, paying special attention to potential missing equipment or redundant equipment. Safety and adequate control systems should also be questioned. 4. Follow-up. If there are unanswered questions which need to be addressed, the design team should perform the necessary analysis. Corrections made during the review should be noted and added to the PFD. Notes describing issues, concerns, and future steps should be distributed after the meeting adjourns. 5. More PFD Reviews. Depending on the number of changes performed during the review process, further review process may be necessary.
