Hi all...
There are basically 3 types of process flow diagram in chemical industry.
1. Block Diagram: It is a process description and flow direction depicted in the form of blocks. Evry unit operation is represented as a block. In this you have no need to show any controls.
2. PFD: Process Flow Diagram : In this u can simply replace the blocks in the Block Diagram and addition to it you have to show some major controls which affects the process more or without which plant can be prone to accidents. You have to mention Mass and Energy balance on the same sheet. You can mention stream no. and details of thse stream on PFD.
3. PID (Process and Instrumentation Diagram): This is the next step to PFD. Wher you can show all the controls, details of equipments like size, design pressure/temp, insulation,nozzle details etc. You have to mention line sizes. It is the basic document and considered as basis for the construction of plant.
