The sieve tray is a type of tray that consists of a perforated with no moving part. In this type of tray, the produced vapor from the mixture rises from holes to the tray above. The energy produced from this very vapor prevents the liquid from getting down through the holes. This type of tray has a better capacity along with a moderate efficiency as compared to the valve tray and the bubble-cap tray. Despite this, the sieve tray has limited flexibility in terms of operating. In terms of the size of the sieve tray, it typically ranges from ¼” to 1”. The sieve trays with smaller sizes reduce the weeping. At the same time, those with larger sizes are all employed in fouling and the related services.
