3 days PGP/PROCREP
- Technical staff using process diagrams.
- This course provides practical keys to read, understand and use process diagrams.
- Upon completion of the course, participants will be able to:
- explain the symbols of a PID legend,
- read and understand a process described with PFD or PIDs,
- efficiently participate to a PID review.
- Basic knowledge of industrial equipment (rotating, static, thermal, instrumentation).
Ways and means
- Various examples issued from refining/chemical processes.
- Use of a set of complex PIDs to understand process flow, instrumentation loops, equipment characteristics, …
- PID review with checklist/HAZOP initiation.
BLOCK DIAGRAM 0.25 day
- Splitting a process in blocks. Elaborating a block diagram.
PROCESS FLOW DIAGRAM (PFD) 0.25 day
- Use of a PFD, added value compared to the Block Diagram. Type of information included in a PFD.
- Symbols used for each element.
- Importance of Utility flow diagrams (UFD). Complementarity with Process flow diagrams.
PIPING & INSTRUMENTATION DIAGRAM (P&ID) 1 day
- Purpose of PIDs: users from engineering phase to operation.
- Process and utilities P&IDs. Key elements indicated on PIDs.
- Elaboration, rules, organization of a PID, level of detail. notes, holds, comments.
- Contents of a P&ID: equipment, piping, instrumentation, links between them. Incorporation of packages and skids. Evolution according to design/operation phases.
- PID symbols (PID 0 or PID legend): typical symbols (ISA-5-1984).
- Documents associated with a PID (piping classes, isometrics, …).
P&ID REVIEWS 0.5 day
- Design reviews: Focus on HSE and Operability with HAZOP review.
- Organization of the review, selection of attendees. Action plan. Validation. Reporting and follow-up process.
