Liquid Collector Tray

This deck type liquid collector is versatile and can be used in all towers. Liquid volume and Residence time are controlled by utilizing tall risers on the tray deck. Sumps can be added on one side, both sides, or across the center to facilitate liquid withdrawal. This collector can provide 25% to 40% open area. Mid-span support beams are required in large columns >2000mm (78 inches) ID.

The deck and optional sump(s) rest on a ledge/tray support ring and the plate can be seal-welded. Gas risers can be made in sections/pieces to allow installation through a manhole where they can be subsequently welded to the seal welded deck.
