An improved tray assembly for vapor liquid contact towers. A layer of mesh packing is disposed atop a cross-flow sieve tray in a process column for improving mass transfer efficiency. The mesh packing is secured upon the sieve tray, which in one embodiment is comprised of closely spaced rods of trapezoidal cross-section. The mesh packing then gives rise to inhibition to incipient bubble formation, a more uniform froth height and reduced back-mixing across the tray. |
