Chemical Reaction Engineering A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m³ and volumetric flow rate 1m³ /h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m³ . The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 kmole/m³ , the volume of the mixed flow reactor should be increased by a factor of 7 6 44015 3 7 6 44015 3 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Sometimes, batch process is preferred over continuous process, when the product Neither A nor B Sales demand is fluctuating Both A & B Quality & yield can not be achieved in continuous processes, because of long residence time Neither A nor B Sales demand is fluctuating Both A & B Quality & yield can not be achieved in continuous processes, because of long residence time ANSWER DOWNLOAD EXAMIANS APP
