2. A gas mixture at 1.0 atm pressure containing air and solute A is contacted in a single stage mixer continuously with pure water at 30 °C. The two exit gas and liquid streams reach equilibrium. The inlet gas flow rate is 100 kg mol/h, with a mole fraction of A being 0.20. It is desired that the exiting gas contain an A mole fraction of 0.01. Calculate the flow rate of liquid required to achieve this separation. Assume that...

A solute A is being transferred from a binary gas mixture of A and C into a pure liquid solvent B in a counter current packed tower with a cross sectional area of 0.2 m2. The inlet gas contains 5 mol% of A and its desired to recover 87% percent of A from the gas stream. The feed gas flowrate is 3.7 mol/s and the liquid solvent inlet flowrate is 13 mol/s. ky’ah = 40 mol/m3s and kx’ah = 60...

A contaminant (A) is to be removed from air at 293 K and 1.013x10 Pa in a counter current packed tower which has a diameter of 0.6m. Pure water will be used as the absorbent. The inlet gas flow rate is 80 mol.ms. Under these conditions the overall capacity coefficient (K,a) is assumed to be 80 mol.ms.AY. The mole fraction of the contaminant in air should be reduced from 0.071 to 0.004. The tower will operate at 293 K. Determine...

A packed tower
(cross-sectional area: 0.093 m2) is filled with 25.4 mm ceramic
rings and it is used for SO2 absorption from air by using pure
water inlet. The entering gas contains 20 mol% SO2 and the leaving
gas is mandated to contain 2 mol% SO2 before being discharged into
the air. The air flow rate is 6.53 x 10-4 kgmol air/s while the
water flow rate is 4.2 x 10-2 kgmol water/s. The volumetric film

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
