A gas stream containin 3.1% A is passed through a packed column to remove 98% of the A by absorption in water. The absorber will operate at 25 0C and 1atm and the gas and liquid rates are to be 210 mol/hr/m2 and 1100 mol/hr/m2, respectively. Mass-transfer coeeficients and equiilibrium data are given below: y* = 3.2x (at 25 0C), kxa = 2100 mol/hr/m3 , kya = 550 mol/hr/m3   Find Noy, Hoy and ZT. assuming isothermal operation and negligible changes in all flow rates. WHat percent of the total mass tranfer resistance is in the gas phase? Calculate ZT using Nox, and Hox

Question

A gas stream containin 3.1% A is passed through a packed column to remove 98% of the A by absorption in water. The absorber will operate at 25 0C and 1atm and the gas and liquid rates are to be 210 mol/hr/m2 and 1100 mol/hr/m2, respectively. Mass-transfer coeeficients and equiilibrium data are given below:

y* = 3.2x (at 25 0C), kxa = 2100 mol/hr/m3 , kya = 550 mol/hr/m3

 

Find Noy, Hoy and ZT. assuming isothermal operation and negligible changes in all flow rates. WHat percent of the total mass tranfer resistance is in the gas phase? Calculate ZT using Nox, and Hox.
