1500 m^3/h of a gas mixture containing 20 mole% solute and rest inert enters the absorber at 250 K temperature and 106.6 kPa pressure to remove 80% of original solute. solute free water used for absorption contains 10 mole% solute when it leaves the tower at the bottom. calculate the solvent flow rate to tower.

A mixture containing 20 mole % butane, 35 mole % pentane and 45 mole % hexane...

A mixture containing 20 mole % butane, 35 mole % pentane and 45 mole % hexane is to be separated by fractional distillation into a distillate product with a composition 95 mole % butane, 4 mole % pentane and 1 mole % hexane, and a bottoms product. The recovery of butane in the distillate must be 90%. Determine the composition of the bottoms product.

1. A gas mixture containing a solute with a concentration of Y1=0.02 to be absorbed in a packed tower. The gas-liquid equilibrium is described by: Y*=1.0X. (a) (10%) To achieve a 99% solute recovery, calculate the required gas phase overall mass transfer unit NtOG and the composition X1 at the liquid exit. X2=0.0001 at the liquid inlet with L/G=1.2. (b) (10%) For pure liquid inlet with L/G=0.8, what is the maximum percentage solute recovery? 2. For a packed tower for...

1) A gas mixture containing 75% air, 20% of A and 5% of B (by volume) is in equilibrium with an aqueous solution of A and B at a temperature such that the saturation pressure of pure A is 3 bar, and that of pure B is 8 bar. Estimate the composition of the liquid if the total pressure is 2 bar. State any assumptions you have made.

A solution containing 50 mL of 2 x 10 -3 M of an indicator H 2 In is measured to have an absorbance of 0.240 at 540 nm with a 1 cm thick cuvette. After 50 mL of 2.8 x 10 -3 M NaOH was added to the solution, the absorbance became 0.048. A second solution containing 50 mL of 2 x 10 -3 M of the same indicator in its basic form, In = , is measured to have...

1. you are given a .5 m^3 container containing 9 moles of an ideal diatomic gas at 0° C, and you want to allow it to reach room temperature (20° C) while staying at the same pressure. You have a choice of holding the volume constant while heating it (process A) and then slowly decompressing the gas isothermally (process B) or simply heating it while maintaining pressure (process C). a) What is the pressure of the gas? b) What is...
