Process flow diagram. A process flow diagram pfd is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. A process flow diagram pfd is a type of flowchart that illustrates the relationships between major components at an industrial plant. The pfd contains the bulk of the chemical engineering data necessary for the design of a chemical process. Its most often used in chemical engineering and process engineering though its concepts are sometimes applied to other processes as well.
The pfd displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Process flow diagrams pfds are used in chemical and process engineering. Generally a process flow diagram shows only the major equipment and doesnt show details. The pfd displays the relationship between major equipment of a plant facility.
It also consists of the process piping and major parts details. Process flow diagrams should include the information regarding the connection between various systems. Process flow diagrams are usually drawn on a large sheet of paper. Process flow diagram pfd is a drawing which essentially captures the process flow for a processing plant.
Pfds are used for visitor information and new employee training. A process flow diagram pfd is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment.
