Research output: Contribution to journalArticlepeer-review


This article considers processes involving two reactants and two reactions It is demonstrated that plantwide control relying on self-regulation results in regions of state multiplicity or unfeasibility, even if the stand-alone reactor has a unique, stable operating point. Moreover, when selectivity reasons require low per-pass conversion, instability is very likely.
