Pfdicons – Draw process flow diagrams in chemical engineering
This package provides TikZ shapes to represent commonly encountered unit operations for depiction in process flow diagrams (PFDs) and, to a lesser extent, process and instrumentation diagrams (PIDs).
The package was designed with undergraduate chemical engineering students and faculty in mind, and the number of units provided should cover-in Turton’s estimate – about 90 percent of all fluid processing operations.
