Question

Pick out the wrong statement.

a.

Packed towers are preferred for vacuum operation, because the pressure drop through the packing is less and they (packings) also lessen the possibility of tower wall collapse.

b.

Packed towers are preferred over plate towers for handling corrosive and foamy liquids.

c.

Diameter of randomly packed tower is normally more than 1.2 metres.

d.

Due to uneven supply and improper distribution of liquid, problem of channeling, loading & flooding is generally encountered in packed towers.

Answer: (c).Diameter of randomly packed tower is normally more than 1.2 metres.
