Dynamic simulation of reactive distillation: An MTBE case study

Dynamic simulations of a 15 stage MTBE reactive distillation column have been performed with the SPEEDUP flowsheeter. The simulations confirm that the column configuration with fixed bottom outflow rate can display steady-state multiplicity. Changes in the column operation (feed flow rate or composi...

Description
Summary:	Dynamic simulations of a 15 stage MTBE reactive distillation column have been performed with the SPEEDUP flowsheeter. The simulations confirm that the column configuration with fixed bottom outflow rate can display steady-state multiplicity. Changes in the column operation (feed flow rate or composition) can cause a jump from one steady state to another or trigger oscillations. The observed steady-state multiplicity remains when the reboiler temperature is fixed rather than the bottom flow rate.
