A. It is preferred to use a vertical condenser for condensation of vapor from a distillation column without sub-cooling
B. Draining of residual liquid on tray during shut down of distillation column is facilitated by weep holes
C. Random packing a packed tower offers the advantage of lower pressure drop and higher throughput of fluids as compared to regular/stacked packing
D. Risers are generally not connected to the plate in a distillation coloumn by bolts, rivets or welding

A. Are easier to clean
B. Are less prone to fouling
C. Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less
D. None of these

A. Low cost
B. High latent heat
C. Non-corrosive condensate
D. High film co-efficient

A. Liquid gradient on the tray
B. Lower skirt clearance
C. Lower static submergence
D. Small downcomer liquid seal
