The liquid is maldistributing, channeling down the wall. The packing is still fine—but the distribution is a disaster."

That night, Aris didn't go home. He sat in the control room, the massive book open on his lap, cross-referencing pressure drop correlations.

Aris nodded slowly. He opened his Sinnott & Towler to Chapter 12, "Separation Columns." He ran his finger down a table labeled Typical Distributor Types and Turndown Ratios . "We found it," Priya said

"But the vendor's data sheet says 2.0 is the minimum," Priya countered. The original design assumed a gas-liquid ratio of 2
