Mass Transfer MCQs

In most of the mechanically agitated liquid-liquid extractors, baffles or horizontal compartmental plates are provided, which helps in

In a single stage extraction process, 10 kg of pure solvent S (containing no solute A) is mixed with 30 kg of feed F containing A at a mass fraction x_f = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at x_B = 0.5 and x_R = 0.05 respectively. The total mass of the extract phase is (in Kg)

Reboiler is considered as one theoretical plate, because

Danckwerts developed the __________ theory.

The change in enthalpy, when a unit quantity of gas is absorbed by relatively large quantity of adsorbent (on which a definite concentration of the adsorbed gas already exists) is termed as the

In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because
