Properties of the reactive flash system

Remarks data are taken from Rodriguez et al. (2001, 2004) accordingly, the reactant is the light-boihng component. 

Variety 1. boundary-limit set (BL) a limit point occurs at a feasibility boundary. 

Variety 3. cross-and-Iimit set (CL) the position of one limit point changes relative to one solution located at the feasibility boimdary, 

Variety 4. corner set (C) the bifurcation parameter and the state variable are, simultaneously, at their boundaries. 

Because the defining conditions can be solved for the state variables and two parameters e.g. f and q), the above mentioned varieties are said to be of codimension-2. The dynamic model of the reactive flash contains several algebraic, but only one differential equation, when the holdup and pressure are fixed and the phase equilibrium is instantaneous. Such one-dimensional systems cannot exhibit Hopf bifurcations leading to oscillatory behavior. Therefore, dynamic classification is not necessary.
