An alcohol manufacturing facility emits air with 500 ppm ethanol. The air flows out several roof vents at a total flow rate of 1000 m³/min (at 25 ° C and 1 atm). The facility is required to collect all the vented air and route it to a bio filter to control total emissions to less than 30 kg of ethanol per day. Calculate the required control efficiency.
