Question

You are exploring different methods to purify process water from the environmentally hazardous substance A.
With the help of a catalyst, you have managed to make A decay to B and C in a batch reactor:
A (aq) → B (g) + C (g)
The reaction is of the first order, r = - k [A] with k = 1.16 * 10^-3s^-1.
Assuming that 25 m³ / h of process water containing 0.010 kmol / m³ A should be treated so that the concentration of A drops to 0.010 mol / m³, how much working volume on the batch reactor is needed? The time for emptying and filling (cleaning is not needed) is estimated to be 15 minutes.

Answer 1

using given rate we can find the volume for given flowrate and maintaince time
