![]() A summary of the streams and their numbers should also be detailed on a separate table. On the process flow diagram, all streams should be labeled and identified with a number. For more details on how to name process equipment, see "Naming Equipment". Additionally, each piece of equipment should be named and listed on a table along with a description of the name. Notable information that should be included should be major process equipment and followed by a short description. ![]() On the process flow diagram, there are several pieces of information that must be included while there are some optional information that can be included to make the PFD more specific. The PFD differs from a block flow diagram (BFD) in that the PFD is more detailed and conveys more information than the BFD, which only gives a general sense of flow of information. The PFD shows the sequence of flow through a system through the various equipment (such as piping, instrumentation, and equipment design) and details the stream connections, stream flow rates and compositions and operating conditions through the plant layout. Additionally, the most effective way of relaying information about a process design is the use of process flow diagrams. It is absolutely necessary that chemical engineers know how to read process flow diagrams because it is the primary method of detailing the process and design information. The process flow diagram (PFD) is a critical component of process design. 7.2 Example 2: Simplified Nitric Acid Process.6.2 Examples of Equipment Summary Tables.4.5 Utility Streams in Process Topology.4.4 Symbols for Fluid Handling Equipment. ![]() 4.3 Symbols for Heat Exchanger Equipment.3 Categorization of Information In a Process Flow Diagram. ![]()
