Process Flow Diagram (PFD) in AutoCAD 2D | Complete Step-by-Step Chemical Engineering Project .

In this video, I have created a complete Process Flow Diagram (PFD) in AutoCAD 2D from scratch, following industry-style practices used in chemical and specialty chemical plants. The project is based on a Hot Oil Heating System, where an organic liquid flows from a storage tank through a pump and a shell-and-tube heater before reaching the product tank. This video covers: • PFD development from a blank AutoCAD file • Equipment symbols and tagging (T-101, P-101, E-101) • Process stream routing and flow direction • Stream data representation (flow rate, temperature, pressure) • Utility integration using a hot oil system • General notes, design basis, legend, border, and title block • Difference between PFD and P&ID (practical understanding) Software used: AutoCAD 2D Application area: Chemical Engineering / Process Design / Specialty Chemicals This video is intended for chemical engineering students and early-career engineers who want to understand how industry-style PFDs are actually prepared. Feedback and suggestions are welcome. #ChemicalEngineering #ProcessFlowDiagram #PFD #AutoCAD #ProcessEngineering #ProcessDesign #SpecialtyChemicals
