All of the following are part of flare systems except (a) Extruders b) Steam ring (steam injection system) (c) Knockout drum (d) Pilot flame Q27. Absorption is a process in which atoms or molecules transfer from a ) phase into a ) phase (a) Liquid, solid (b) Liquid, plasma (c) Gas, liquid (d) Gas, sold 028. In distillation, after the level builds up on a tray, it flows over the weir, and the liquid goes into (a) Separation channel b) Downcomer (c) Entrapment device (d) Overhead condenser

Explanation / Answer

Answer to question no. 24

Blowdown is carried out in boiler to reduce the solid content in the water stream. As per the standard reference the ideal range of blowdown is no less than 5% and not exceeding 20 %

Hence the correct option is option d) 5- 20 %

Answer to question no 25

Refrigeration system generally requires

1. Evaporator where we cool our main process feed

2. Compressor where we compress the evaporated coolant

3. Condensor to cool the compressed coolant

4. Throttling system (Diffuser) to reduce the pressure of the coolant

From the option provided the correct option is option A) diffuser, compressor, compressor and evaporator.

Answer to question number 26

Extruder is not a part of flare system. At times depending on the feed that is to be burn in the flare unit we require steam to mix it with it and knockout drum to store the excess feed that will be burnt later on in the flame header. and pilot flame to finally burnt it

Hence the answer is option a) extruder

Answer to question no. 27)

Absorption is a process where in we intend to absorb a solute which is present in the gas phase in liquid phase by selecting a liquid in which the affinity of solute to get absorbed is greater than that in gas phase.

Hence the answer is option C) Gas, liquid
