A block flow diagram (BFD) is a drawing of chemical processes used to simplify and understand the basic structure of a system. Blocks in a BFD can represent anything from a single piece of equipment to an entire plant. For a complex process, block flow diagrams can be used to break up a complicated system into more reasonable principle stages/sectors.
