The gas SO2is being scrubbed from a gas mixture by pure water at 303 K and 1.013x105Pa. The inlet gas contains 6 mol % SO2and the outlet 0.3 mol% SO2.The tower cross-sectional area of packing is 0.426 m2. The inlet gas flow is 13.65 kg mol inert air/h andthe inlet water flow is 984 kg mol inert water/h. The mass transfer coefficients areHL=0.436 m and kGa=6.06x10-7kg mol/s m3Pa and are to be assumed constant in thetower for the given concentration range. Use equilibrium data from Appendix A.3. Bynumerical or graphical integration, determine NG.Calculate the tower height. (Note: Theequilibrium line is markedly curved, so numerical integration is necessary even for dilutemixture.)
A sealed rigid tank of 1 m3 capacity contains 1.2 kg of water at 1 bar and 99.63 °C. To this tank we add heat until the pressure increases to 3 bar. What is the temperature at the end of the heating?
The feed (CAo= 1.0, CRo= 0, CSo= 0) enters two mixed reactors in series (?1= 2.5 min,?2= 10 min) knowing the composition in the first reactor (CA1= 0.4, CR1= 0.4, CS1= 0.2),find the composition leaving the second reactor (using fractional yield co..

Calculate the ?S for the transfer of one mole of octane to water using the change in multiplicities assumed for the first shell of water molecules surrounding the molecules.
A beaker filled with an equimolar liquid mixture of ethyl alcohol and ethyl acetate evaporates at O°C into still air at 101 kPa (1 atm) total pressure. Assuming Raoult's law applies, what will be the composition of the liquid remaining when half t..
Into a barrel containing 33.2 bbl (US) of water containing 0.0012 mol/L of a blue dye you pour V2 yd3 of water containing 8.91 M of the dye. The final concentration of the dye in the barrel is 7.91 mol/m3 after it's well-mixed. What is V2 is yd^3?
Design a condenser for the following duty: 45,000 kg/h of mixed light hydrocarbon vapors to be condensed. The condenser is to operate at 10 bar. The vapor will enter the condenser saturated at 60 °C and the condensation will be complete at 45 °C.
