TRITON® High Capacity Fractionation Trays - Koch-Glitsch - #1

to the TRITON tray's capacity advantage. With moving valve trays, vapor flow tends to concentrate in the center of each deck. In some cases, valves flutter and close on the deck's perimeter. Jet flooding occurs when entrainment from the center of the deck reaches the next tray, a phenomenon that restricts tray capacity.

In contrast, TRITON trays have no moving valves to contribute to uneven vapor distribution. In fact, the forward-lateral push imparted by the tapered valve design promotes uni­form liquid and vapor distribution across the entire tray deck.The valve cover, which extends beyond the deck opening, deflects and directs the vapor to a greater degree than moving valves and punched-from-the-deck fixed valves.This phenomenon promotes a low, even spray height across the deck, suppressing jet flooding and permitting operation at higher vapor rates.

The patented PROVALVE valve design prevents the likelihood of valve leg or deck wear while eliminating the poten­tial for popped, fouled or stuck valves. The valve actually minimizes mainte­nance demands and decreases the inci­dence of tray fouling and damage.

With TRITON trays, revamping your column to increase capacity doesn't require great expense or downtime. In fact,TRITON trays can replace conven­tional valve trays on a one-for-one basis using existing column attachments. This keeps the cost of significantly upgrading your system to a minimum.

TRITON™ high-capacity fractionation trays by Koch-Glitsch can significantly increase throughput in your trayed tower.

Two major design innovations have been incorporated into the TRITON tray. First, the patented downcomer design increases the tray's active area. Then, proprietary PROVALVE® fixed valves optimize bubbling and liquid flow across the deck. In addition to improv­ing the tray's hydraulic characteristics, the forward-lateral push imparted by the PROVALVE fixed valve also keeps the tray deck clean and free from fouling.

The bottom line: TRITON trays can increase your column's capacity sub­stantially over conventional valve trays while providing improved mass trans­fer efficiency and lower pressure drop.

With conventional valve trays, the

area under the downcomer is inactive to accommodate the liquid flow from above. However, the innovative down-comer design of the TRITON tray turns this dead space into active bubbling area for greater vapor capacity.

The fixed-open design of the patented PROVALVE fixed valve contributes further
