Mass Transfer 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 xf = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at xB = 0.5 and xR = 0.05 respectively. The total mass of the extract phase is (in Kg) 8.89 8.25 6.89 10 8.89 8.25 6.89 10 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In continuous distillation, the internal reflux ratio (Ri) and the external reflux ratio (Re) are related as Ri = Re/(1 + Re) Ri = Re Ri = Re/(1 - Re) Ri = (1 - Re)/Re Ri = Re/(1 + Re) Ri = Re Ri = Re/(1 - Re) Ri = (1 - Re)/Re ANSWER DOWNLOAD EXAMIANS APP
