Tonight, that compass was pointing toward ruin.
He wrote the solution on a scrap of process flow diagram. He underlined the page number in the book. Then, for the first time in weeks, he leaned back and closed his eyes.
He grabbed a calculator. He had not accounted for the viscosity safety factor. The 15% pushed the design pressure drop above the available head. The liquid wasn't channeling because of the ratio—it was channeling because it didn't have enough energy to push through the distributor tray evenly.

At 2:37 AM, he found it. A tiny footnote on page 691, buried in the fine print of an example problem about a depropanizer column. It read: "For systems with significant liquid viscosity variation (>2 cP), add a 15% safety factor to the distributor pressure drop calculation."
"Page 687," he murmured. "The V-notch weir distributor. It’s rated for a turndown to 1.6 ratio. We're at 1.8. We're inside the operating window." Tonight, that compass was pointing toward ruin
"But the vendor's data sheet says 2.0 is the minimum," Priya countered.
Outside, the quench tower hummed a steady, quiet song. And the brown leaf skittered past the flare stack, toward a new day. Then, for the first time in weeks, he
His star protégé, a sharp young woman named Priya, knocked on his office doorframe. She held a tablet, but her eyes held the haunted look of someone who had just run a simulation that ended in a red, flashing error.
