Tubular Reactor with Nonisothermal Cooling Jacket

Application ID: 67

The model describes a tubular reactor where propylene oxide (A) reacts with water (B) to form propylene glycol (C):

A + B -> C

Since water is the solvent and present in abundance, the reaction kinetics may be described as first order with respect to propylene oxide:

R = k*C_A

Alternatively, a second-order reaction can also be implemented according to:

R = kfC_ACB - kr*CC

The reaction is exothermic and a cooling jacket is used to cool the reactor. The reactor is modeled in 2D axisymmetry and the simulation results yield composition and temperature variations in both the radial and axial directions.
