What is the mole fraction in instantaneous distillate if: Moles of liquid in residue at start W0= 2000 Moles of liquid in residue at end W= 500 Mole fraction in liquid at start X0 = 0.3 Mole fraction in liquid at end X= 0.4

Correct Answer: 0.27
XD = W0X0 –WX/W0-X, hence Xd= 0.27.

Find the distillate and the residue rates in mole/hr, if the feed rate is 100 mol/hr; The compositions of feed, distillate and residue in terms of mole fraction are 0.65, 0.9 and 0.2.

Find the heat given( in KJ) to the feed for the flash vaporization process if the ratio of residue to the distillate is 0.65 and the enthalpy of feed, distillate and the residue are 500, 800 and 200 KJ/kmol respectively. The feed rate is 100 kmol/hr.

Compound A is extracted from a solution of A + B into a pure solvent S. A Co-current unit is used for the liquid-liquid extraction. The inlet rate of the solution containing A is 200 moles of B/hr.m2 and the solvent flow, rate is 400 moles of S/m2.hr. The equilibrium data is represented by Y = 3X2, where Y is in moles of a A/moles of B and X is in moles A/moles of S. The maximum percentage extraction achieved in the unit is
