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. This PFD shows the process of YSG
type modified asphalt production process flow. Download EdrawMax and start creating PFD diagrams. Though its concepts are sometimes applied to other processes, it is most commonly employed in chemical engineering and process engineering. It can be used to document, improve, or model a new process. A Process Flow Diagram can be used for a variety of reasons. 1. To document a process for better comprehension, quality control, and employee training. 2. To make a process more efficient and repeatable by standardizing it. 3. To examine a process in order to increase its efficiency. It aids in the identification of redundant stages, bottlenecks, and other inefficiencies.
