Sinopsis

Process Control Engineering is the most important branch of Chemical Engineering. Ask any panel board operator in a petrochemical plant or refi nery. The P & IDs (Process and Instrumentation Diagrams) are the defi nitive engineering documents describing how a plant works. The Process Control Engineer has the ultimate responsibility for creating, maintaining, and interpreting the P & IDs. It is his job — and perhaps his most important function — to explain to the panel operator how the control valves interact with the process plant to achieve unit stability.

I don ’ t know why I wrote “ his job, ” because half of the Process Control Engineers I work with are women. Women often make better control engineers and panel board operators than men, because they are more patient. Men often are driven to reach some distant goal quickly. Women, being patient, will take a more measured approach to restore stability during a process upset
