Welcome to “Back of the Envelope” — a column where each article gives you one engineering calculation you can do

A pharmaceutical plant in Suzhou laid out their entire extraction workshop based on process flow—pumps here, columns there, everything neat

After 13 years, I can divide my P&ID mistakes into two categories: the ones I caught before construction, and the

1. Most pumps don’t fail. They’re murdered. I’ve investigated maybe 40 pump failures. Actual manufacturing defects: two. Everything else: wrong

Noise is the most overlooked pollutant in industrial plants. It doesn’t leave a visible trail. It doesn’t show up in

The equipment layout drawing is the first document the construction team pulls out. Before P&IDs. Before isometrics. Before datasheets. If

A bad P&ID costs you during commissioning. A P&ID review that catches the bad P&ID saves you during commissioning. I’ve

The pipe rack is the spine of a process plant. It carries every utility, every process line, every instrument cable,

You send a datasheet to a pump vendor. Two days later, it comes back with 14 questions. You answer them.
