When we checked the vapour pressure at the exit to the adiabatic reactor in Example 3 where
the temperature is 360 K, we found the vapour pressure to be about 1.5 MPa for isobutene,
which is greater than the rupture pressure of the glass vessel being used. Fortunately, there is
a bank of ten partially insulated (Ua = 5000 kJ/h.m3
.K) tubular reactors each 6 m3 over in the
storage shed. We are also going to lower the entering temperature to 310 K. The reactors are
cooled by natural convection where average ambient temperature in this tropical location is
37 deg C. The temperature in any of the reactors cannot rise above 325 K.
Plot X, Xe, T and the reaction rate along the length of the reactor. Does the temperature rise
above 325 K?
