Abstract
A vapor-liquid tray is provided which achieves markedly higher vapor loading and tray efficiency at all liquid loadings, and with little or no increase in pressure drop. Vapor loading is increased via a multiplicity of locally co-current liquid recirculating compartments, preferably with diagonal structure producing diagonal co-currency. Tray efficiency is increased by highly effective horizontal staging via a convergent-divergent liquid flowpath, preferably with structurally integrated tray downcomers. The advantageous features are also applicable individually. Referring to FIG. , symmetric tray partitions separate the active area of tray into a central section and two peripheral sections. The peripheral sections have tray downcomers and tray weirs . The central section tray weir is . Compartment partitions divide the liquid flowpaths into multiple compartments, each having compartment weir with liquid recirculation passages
