Steady-state multiplicities in reactive distillation columns for the production of fuel ethers MTBE and TAME: theoretical analysis and experimental verification

Impact of Mass Transfer on Modelling and Simulation of Reactive Distillation Columns

“…crossing of the practical stability limit, study of safe operating conditions, investigation of conditions and trajectories which can shift the reactor/column from one steady state to another one and the determination of a safe start-up and shut down procedure. Mohl et al (1999) showed that the multiplicity found for a reactive distillation column has the same cause as that found for a continuous stirred tank reactor (CSTR). The existence of multiple steady states can result in both technological problems and dangerous situations.…”

Reactive Distillation

“…Mohl et al [36] experimentally demonstrated the existence of multiple steady states in the synthesis of tert-amyl methyl ether.…”

Control of Quaternary Ideal Endothermic Reactive Distillation with and without Internal Heat Integration

“…In literature, the nonlinear nature of many RD columns, in the form of steady-state multiplicity and nonlinear dynamics, has been reported [4,[12][13][14][15][16][17]. Moreover, with the integration, the total control degrees of freedom for regulating both separation and reaction are reduced.…”
