A process flow diagram is a graphical tool most commonly used by business process management professionals BPM and chemical engineers. PFD helps to understand the process, provide quality control, and increase efficiency. It is used to get a top-down understanding of how different types of equipment and chemicals work in the industrial plant.
Bayer process, advanced control is becoming a preferred tool to deliver return on capital employed. Primarily, this is being done using the prevailing control technology, multivariable predictive control. This paper will discuss the applications and benefits of this technology in the alumina industry.
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,
