Due to neighborhood complaints, a livestock manager is now required to decrease the concentration of ammonia discharged to the air to 1000 ug/m'. She wants to remove ammonia (NH3) from two air waste streams by adsorption and reaction in a well- mixed reactor (volume = 2m'). Homework 4 (assigned September 29, 2019) N. B. Saleh Due Friday, October 04, 2019 CE341 Consider the following treatment system, where T-30 C and P=1 atm. C1= 5 ppmv Q1 = 0.009 m'/min Adsorption: 20 ug NH,/min Reaction: 1x10# mg NH3/(m's) Cout- ? ug/m' Qout = ? m'/min Reactor Volume=2m' C2=3000 ug/m' Q2 = 0.001 m'/min a. Circle the control volume that you will use to write mass balances on air and NH3. b. Write the steady state mass balance for air. What is Qout (m'/min)? c. Write the non-steady state mass balance for NH3. When will the air leaving the reactor be in compliance with the local ammonia regulation (1000 ug/m')? Assume that the initial concentration of ammonia in the reactor is 3000 ug/m'. Express the time in minutes.
