a gas stream is entering an absorber is 20mol% CO2 and 80 mol% air. the flow rate is 1 m^3/min at 1 bar and 360 K. when the gas stream exits the absorber , 98% of the incoming CO2 has been absorbed into a flowing liquid amine stream
(a) what are the gas stream mass flow rates on the inlet and outlets in g/min?(b) what is the volumetric flowrate on the gas outlet of the absorber if the stream is at 320 K and 1 bar?
