The push for cleaner fuels, tighter product specifications, and higher efficiency is constant. At the same time, operators are dealing with variable feedstock quality and shifting market demand. In this context, the margin for inefficiency is extremely small. Every unplanned shutdown, delayed diagnosis, or suboptimal tower performance directly impacts throughput, emissions, and safety. The challenge is no longer just identifying issues inside process towers. It is how quickly those insights can be turned into action.

Issues in trayed towers such as internal tray damage, missing trays, plugged downcomers and tray foaming can all lead to off-spec production and in some cases, un-anticipated shutdowns. Scanning technology can help you avoid these scenarios by providing you with an assessment of your operating conditions, whilst your process equipment remains online.

The first step to determine liquid maldistribution in a **[packed column](http://www.tracerco.com/processdiagnostics/packed-bed-towers)** is to perform a Tracerco Tru-Grid™ Scan to provide an initial look at the liquid distribution in the packing.  A Tru-Grid™ scan consists of four equal-distant chords, one through each quadrant of the tower.
