A gas stream consists of 90 mole% N2 and 10 mole% CO2. We wish to absorb the CO2 into water. The inlet water is pure and is at 5 °C. Because of cooling coils the operation can be assumed to be isothermal. Operation is at 10 bar. If the liquid flow rate is 1.5 times the minimum liquid flow rate, how many equilibrium stages are required to absorb 92% of the CO2? Choose a basis of 1 mole/h of entering gas. The Henry coefficient of CO2 in water at 5 °C is 875 bar

Question

A gas stream consists of 90 mole% N2 and 10 mole% CO2. We wish to absorb
the CO2 into water. The inlet water is pure and is at 5 °C. Because of cooling
coils the operation can be assumed to be isothermal. Operation is at 10 bar. If
the liquid flow rate is 1.5 times the minimum liquid flow rate, how many equilibrium stages are required to absorb 92% of the CO2? Choose a basis of 1 mole/h of entering gas. The Henry coefficient of CO2 in water at 5 °C is 875 bar
