Stationary states are analyzed of an isothermal chemical reactor connected by direct recycle with a separation unit from which a part of mixture enriched by the initial substances is returned into the reactor. It was found out that recycling can be the cause of the existence of multiple stationary states of system. The effect is discussed of kinetic law of chemical reaction and separation function of separation unit on the number of stationary states and their stability. The method based on the determination of trajectories of pseudostationary states of the initial substance concentrations in phase plane was used for analysis.
