  • Sieve Trayan overview ScienceDirect Topics

    Sieve trays rely on vapor velocity to exclude liquid from falling through the perforations in the tray floor. If the vapor velocity is much lower than design liquid will begin to flow through the perforations rather than into the downcomer. This condition is known as weeping. Where weeping is severe the equilibrium efficiency will be very low.

     · The vapour flow rate in either section of the column is obtained from the mass balance in kmol/hr. This is converted to m 3/s as follows m3/s = (kmol/hr x mol wt.)/(density x 3600) From the continuity equation q = va. Since we know the velocity and the flow rate we can determine the cross sectional area and from that the diameter.
