Multiple steady states in two-phase reactors under boiling conditions
TLDR
In this article, the authors analyzed the nonlinear behavior of two-phase reactors under boiling conditions and identified three necessary conditions for the existence of multiple steady states: the reactant A has to be the light-boiling component, the difference in boiling point temperatures between the reaction A and the product B is sufficiently large, and the order of the reaction B is less than some physical parameter α.About:

Multiple quasi-steady states in a closed loop pulsating heat pipe
TL;DR: In this article, a single loop pulsating heat pipe exhibits multiple operational quasi-steady states and a temporal scaling analysis is presented to estimate the order of magnitude of the equilibrium frequency of phase change and ensuing oscillations.

Role of multiplicity in reactive distillation control system design
M.V. Pavan Kumar,Nitin Kaistha +1 more
TL;DR: In this article, the impact of input multiplicity on the control of a simulated industrial scale methyl acetate reactive distillation (RD) column is studied and a new metric, rangeability, is defined to quantify the severity of inputs multiplicity in a steady-state input-output (IO) relation.

Nonlinear Dynamic Effects in Reactive Distillation for Synthesis of TAME
TL;DR: In this paper, a case study for dynamic simulation of a reactive distillation (RD) process for the production of TAME is presented, where nonlinear dynamic effects such as oscillations, multiple steady states, and internal state multiplicity have been observed under certain conditions.

Analysis of Steady-State Multiplicity in Reactive Distillation Columns
TL;DR: In this article, a relatively simple method to identify multiplicity in reactive distillation due to the interaction of reaction and distillation is proposed, where the nonlinear generation term and linear removal term, f

Effect of Competing Reversible Reactions on Optimal Operating Policies for Plants with Recycle
TL;DR: In this paper, a simple classification procedure for determining optimal steady-state operating policies for plants with recycle has been developed by Griffin et al. to cover complex process chemistries and demonstrates that the optimal operating policy can change depending on which reaction(s) is(are) reversible and the magnitude of the equilibrium constant(s).
