A Factory Process Flow Diagram (PFD) is commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. As shown in the below customizable diagram, the PFD displays the relationship between major equipment of a factory and does not show minor details such as piping details and designations. There are a couple of steps that should be considered while creating a factory PFD for your presentation. Determine the main components of the process, then order the activities as to how the factory operates. Then choose the correct symbols for each activity and make the connection between these activities. Indicate the beginning and end of the process before reviewing the factory process flow diagram.
