A gas stream contains 4mol% NH, and its ammonia content is to be reduced to 0.5mol% in a packed absorption tower at 293K and 101.3kPa. The pure inlet water flow is 68.0kmol/h and the total inlet gas flow rate is 57.8kmol/h. The tower diameter is 0.747m. The film mass transfer coefficients, ka and kya are 0.169 and 0.0739kmol/s.m respectively. Using the design methods for dilute gas mixtures, calculate the tower height using a.ka bka c. Which design would you say is the most accurate and why? Quote all concentrations to 3 decimal places. Below is the equilibrium data for this system at 293K and 101.3kPa. (Hint: Insert a best-fit line that passes through the origin): XA, mole fraction of ammonia in liquid YA, mole fraction of ammonia in gas 0 0 0.021 0.016 0.026 0.020 0.031 0.024 0.041 0.033 0.050 0.042 0.074 0.066 A gas stream contains 4mol% NH, and its ammonia content is to be reduced to 0.5mol% in a packed absorption tower at 293K and 101.3kPa.
