Most refining columns were trayed for a design case that no longer matches reality. As crude slates change and rates creep up, the first thing to give is hydraulics — jet flood at the top, downcomer backup, off-spec overheads. The instinct is a new vessel; the answer is usually a smarter re-tray.

We rebuild the hydraulic model from your datasheets and live operating data, find the headroom trapped in old tray geometry, and manufacture drop-in internals — regardless of who supplied the original equipment.
