If you've ever confused a compressor for a turbine or expander while creating or reading a process flow diagram, then this post is for you. This short video tutorial from the incredibly useful Learn ChemE series will familiarize you with different pieces of equipment, what they are, and the basics of what they do—and, of course, it shows you how they are represented on PFDs.
This first tutorial gives a general overview, but be sure to check out Part 2 (Specifications), Part 3 (Materials of Construction), and Part 4. And if you need more help with any other subject, peruse the extensive list of chemical engineering tutorials in the playlists arranged by subject.
