Q1: 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.

ANS:C - Diameter of randomly packed tower is normally more than 1.2 metres.

The wrong statement is: "Diameter of randomly packed tower is normally more than 1.2 meters." In reality, the diameter of randomly packed towers can vary widely depending on the specific application and requirements. While some packed towers may indeed have diameters larger than 1.2 meters, many others can have smaller diameters, especially in situations where space is limited or where smaller-scale operations are preferred. Therefore, the statement that the diameter of randomly packed towers is normally more than 1.2 meters is not universally accurate.
