The process flow diagram is an essential part of chemical engineering. It conveys a process and the path of its individual components - therefore, it is essential to learn how to read and create one. The process flow diagram is divided into three sections: process topology, stream information, and equipment information.

As the reaction proceeds, the glass transition temperature rises to meet the reaction temperature, and the system vitrifies; that is, the motion of the main chain stops. At this point, the reaction essentially stops for all practical purposes. This has been conveniently described in terms of a time-temperature-transformation cure diagram.

The diagrams frequently focus on energy flow and its distribution to various sources or sinks, represented by arrows, the width of which indicates the amount of energy flow. Material flows are also frequently displayed with Sankey diagrams, and these are described, for example, as material flow charts ( Koelbel and Schulze 1960 ).
