Bubble Cap Trays

Bubble Cap Tray columns are very often used in petroleum refineries.

Here, the gas flows through the openings in the bottom of the bell. The gas then travels through the slits in the edge of the cap and bubbles through the liquid. The liquid is prevented by the bell from flowing down to the lower floors. 

We provide a wide variety of bubble cap shapes and diameters. We also assemble bubble caps specified or supplied by our customers.

Conventional bubble cap trays are well-proven in applications with following conditions:

• large loading ranges
• low liquid loads
• low gas loads
• continuous liquid hold up
• low leakage rates
