Steady-State Multiplicity in High-Pressure Bubble Column Reactors

The effect of pressure on the possible existence of multiple steady states in bubble column reactors is investigated. A mathematical model involving fast pseudo first‐order kinetics is employed to describe the performance of non‐isobaric, non‐isothermal reactors. The numerical analysis reveals that the existence of multiplicity is sensitive to pressure variation, yet high‐pressure operating conditions do not necessarily lead to a higher likelihood of multiplicity in these contactors. Bubble column reactors are widely used in industry for a variety of gas‐liquid and biochemical reactions. The occurrence of steady‐state multiplicity in non‐isobaric bubble column reactors is examined using a mathematical model and the sensitivity of the reactor performance to pressure variation is investigated.
