### Abstract

The paper is devoted to a new approach to steady state multiplicity analysis of methyl tert-butyl ether (MTBE) production by means of reactive distillation. Reactive distillation systems are characterized by input and output multiplicities, which may cause complex and unpredictable behavior of the process. The fundamental mathematical model, which enables to reveal potential sources of nonlinearity of the process, is proposed. As the result of input multiplicity analysis, intervals of one steady state were found for vapor and reflux ratio. Output multiplicity analysis showed three possible steady states in the reactive section of the column, one of which is corresponded to the maximal product yield. The advantage of the method is the ability to find "input-output" multiplicities on every stage of the column by using control parameters of the feed, reboiler and condenser only.
