Question 2. Chemical absorption is commonly used in the chemical process industry to remove hazardous or unwanted components from a gas stream. In this experiment we want to remove CO2 from an air stream by counter-current absorption in a NaOH solution. For the experiment, a dilute solution of NaOH is prepared by adding 1.15L of a 2mol/LNaOH solution to 21.85L deionized water (NaOH tank in the Figure). 0.1L/min from the NaOH solution from the tank and 0.5L/min water are mixed and fed to the top of an absorption column as shown in the Figure. 1.0L/min air (CO2 free) and 0.80L/minCO2 are mixed and fed to the bottom of the absorption column (see Figure). The column operates at 20C and 1 atm. Henry's coefficient for CO2 absorption in water at 20C and 1atm is 1640Pam/mol.CO2 reacts with NaOH as follows: 2NaOH+CO2Na2CO3+H2O Calculate the mole fractions of CO2 and NaOH in all inlet and outlet streams of the absorption column. Assume equilibrium has reached. Question 2. Chemical absorption is commonly used in the chemical process industry to remove hazardous or unwanted components from a gas stream.
