Presentation Transcript

Cstr in series
CSTR in series

  • A first-order reaction with no change in the volumetric flow rate (v = v0) is to be carried out in two CSTRs placed in series.

  • For the 1st reactor:

    • Mole balance :


  • Combine:

    • (2)

      From (1) and (2)



  • Substituting for Cn in terms of conversion and Since the reactors are of equal size, operate at the same temperature, and have identical feed rates. the conversion wilI be the same for each reactor:

    x1 = X2 = ... = Xn = X

    CSTR in Parallel

    • The individual reactor volume

    • Since the reactors are of equal size, operate at the same temperature, and have identical feed rates. the conversion wilI be the same for each reactor:

      • X1 = X2 = ... = Xn = X


    Quiz

    • Drive the design equation for liquid phase second order reaction carried out in CSTRS connected in parallel.
