A modified sieve (that is, T‐By) tray uses a system of weirs and risers to approximate liquid plug flow over a cross‐flow, circular‐section tray. Vapor‐liquid contact is improved using a system of curtain‐pattern vapor holes and intermediate weirs to form cells across the tray that promote liquid mixing into discrete, wellmixed pools and stabilize froth. A theoretical model is used to analyze experimental data, guide tray design, and suggest new strategies for improving performance. These results indicate that tray efficiencies and stabilities can be increased without capacity losses. Pressure drop can also be manipulated to enhance performance.
