Process Flow Diagram (PFD) is a commonly used chart in chemical engineering and process engineering demonstrating the ongoing production flow of chemicals and other types of equipment involved. The concept of the process flow diagram was first pointed out by Frank Gilbreth, an American industrial engineer, in the 1920s.
The process flow diagram (PFD) represents a quantum step up from the BFD in terms of the amount of information that it contains. The PFD contains the bulk of the chemical engineering data necessary for the design of a chemical process. For all of the diagrams discussed in this chapter, there are no universally accepted standards.
