PROCESS EQUIPMENT AND PLANT DESIGN QUIZ

Is economical in operation

Employs a centrifugal pump placed between external downtake from vapor drum and inlet to tube bundle

Employs high velocity, high heat transfer rate and less heating surface requirement

Both B & C

Heat of mixing of normal liquid is assumed to be zero

Molar latent heat of the two components are equal

Sensible heat changes for vapour & liquid are negligibly small

Reflux is not a saturated liquid

Weir height for a bubble cap plate column is the same as that for a seive plate column

Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate

Weir length for a bubble cap plate is the same as that for the seive plate

The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns
