Sieve Tray an overview ScienceDirect Topics

The sieve tray is simply a plate with holes for vapor passage. Although the sieve tray generally has higher capacity, its main disadvantage is that sieve trays will be susceptible to “weeping” or “dumping” of the liquid through the holes at low vapor rates and its turndown capacity is limited. Trayed columns generally provide
