Process Flow Diagram and P&ID

6 weeks · 0 milestones

Produce a Process Flow Diagram (PFD) and a Piping and Instrumentation Diagram (P&ID) for a real or representative chemical or process engineering system to industry standard symbology (ISO 10628 or ANSI/ISA 5.1). The PFD must include: all major process equipment identified with equipment tags, all process streams with stream numbers linked to a stream data table (flowrate, composition, temperature, pressure), the major control loops shown in simplified form, and a process description narrative. The P&ID must include: all equipment with instrument and equipment tag numbers, all instrumentation (sensors, transmitters, indicators, controllers) with ISA function codes, all control loops with instrument tags and signal types, all valves (manual, automatic, check) with valve tags, and line specifications (pipe class, insulation, heat tracing where applicable). Preferred proof: a real PFD and P&ID from a project. Accessible alternative: DWSIM (which includes a PFD drawing environment and equipment library) for the PFD; for the P&ID, draw.io with ISA symbol libraries (free, available as community add-ons) or Lucidchart free tier with P&ID shapes. Proof artifacts: the PFD with stream data table (design artifact) and the P&ID with complete instrument and line annotations (documentation artifact). Verification: a process engineer reviews 'this high-pressure steam line — what line class would you specify, and where is your pressure relief?' — requiring specific reasoning from your own P&ID.
