Stoichiometry
Pure aniline is evaporating through a stagnant air film of 1 mm thickness at 300 K and a total pressure of 100 KPa. The vapor pressure of aniline at 300 K is 0.1 KPa. The total molar concentration under these conditions is 40.1 mole/m³ . The diffusivity of aniline in air is 0.74xl0-5m²/s.The numerical value of mass transfer co-efficient is 7.4 x 10-3. Its units are
Recycling in a process does not help in getting higher extent of reaction
The ratio of the quantity of a reactant present in the reactor feed of a recycling operation to the quantity of the same reactant entering the process as fresh feed is called combined feed ratio
Recycling in a process stream helps in utilising the valuable reactants to the maximum with minimum loss of reactants
Recycling is exemplified by refluxing back a part of the distillate to the distillation column to maintain the quantity of liquid within the column
