Consider a cascade of two continuous stirred-tank reactors with recycle undergoing exothermic first-order chemical reactions. The steady state is described by four nonlinear equations for the reaction conversions , , dimensionless temperature , , and parameter (Damköhler number). The dimensionless equations that describe the steady state are given by [2] (see also [1])
