What is a Process Flow Diagram

A Process Flow Diagram (PFD) is a diagram which shows the relationships between the main components in a system. Process Flow Diagrams are widely used by engineers in chemical and process engineering, they allows to indicate the general flow of plant process streams and equipment, helps to design the petroleum refineries, petrochemical and chemical plants, natural gas processing plants, and many other industrial facilities.

Process Flow Diagram is focused on the representation the major equipment and doesn't show minor equipment details and designations. The PFD of a single unit process can include:

  • process piping;
  • major equipment items, symbols, names and identification numbers;
  • recirculation streams and major bypass;
  • control valves and other valves which influence on the system's work, monitor and control the operations of the processes;
  • flow directions;
  • interconnections with other systems;
  • the set of operational data - pressure, temperature, flow rate, density, operational values for the pumps, compressors, distillation columns and other vessels, composition of fluids, process stream names, amount and composition of all the major process streams, amount of heat, system ratings, etc.

Benefits of Process Flow Diagram

The Process Flow Diagram has a wide set of benefits:

  • gives a clear documentation of a process;
  • allows to define and offers common understanding of processes;
  • helps to build a process visual representation for analysis, discussion, and communication;
  • allows to identify the scope of the process;
  • allows to trace and analyze the process steps;
  • helps to standardize and find areas for monitoring, improvement and increased efficiency in a process;
  • allows to find and detach the steps of the process that are not essential;
  • helps in understanding the logic of complex problems;
  • offers a guidance for managers overseeing operations;
  • shows the plant design basis, the arrangement of major equipment, process lines, main control loops;
  • indicates feedstock, product, main streams flow rates and operating conditions;
  • facilitates communication between programmers and business people;
  • helps programmers to write the programs of any complexity and on the any high level language;
  • helps in debugging process and provides efficient program maintenance;
  • helps to understand and explain to other people the logic of the complex problems and their solution;
  • assists to improve teamwork effectiveness.
