PFD
PFD, or Process Flow Diagram, is a fundamental tool used in chemical engineering to show how industrial processes work. Think of it as a detailed map or blueprint that shows how materials move through a manufacturing plant or facility. It helps engineers and operators understand how different pieces of equipment (like pumps, tanks, and heaters) connect and work together. When you see PFD mentioned in a resume, it typically means the person has experience in designing, reading, or working with these important industrial process diagrams. Similar terms you might see include Process Diagrams, Flow Charts, or P&IDs (Piping and Instrumentation Diagrams).

Example Interview Questions
Senior Level Questions
Q: How do you ensure safety considerations are properly reflected in Process Flow Diagrams?
Expected Answer: A senior engineer should discuss how they incorporate safety systems, emergency shutdowns, and critical control points into PFDs, and explain how they use these diagrams in safety reviews and risk assessments.
Q: How do you manage changes to PFDs in an operational facility?
Expected Answer: They should explain the change management process, including proper documentation, stakeholder approval, updating related documents, and ensuring all affected personnel are trained on the changes.
Mid Level Questions
Q: What software tools have you used for creating PFDs?
Expected Answer: Should be able to discuss common industry software like AutoCAD, Microsoft Visio, or similar tools, and explain their experience in creating and modifying process diagrams.
Q: How do you use PFDs in troubleshooting process problems?
Expected Answer: Should explain how they use PFDs to track process flows, identify potential problem areas, and communicate issues to operators and maintenance teams.
Junior Level Questions
Q: What are the basic elements shown in a PFD?
Expected Answer: Should be able to identify basic components like equipment symbols, process lines, flow direction arrows, and basic process conditions.
Q: What's the difference between a PFD and a P&ID?
Expected Answer: Should explain that PFDs show the basic process flow while P&IDs show more detail including instrumentation, control systems, and utilities.
