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.
