FIELD: chemistry.
SUBSTANCE: adsorption is carried out in a system with a simulated moving adsorbent bed. The method includes washing an intermediate transfer line between a first intermediate transfer line and an extract stream transfer line outside an adsorptive separation chamber. Residual fluid medium is removed from the intermediate transfer line as a result of said washing. The method may include directing the residual fluid medium washed from the intermediate transfer line into a recycle stream for feeding the residual fluid medium into the adsorptive separation chamber.
EFFECT: high purity of para-xylene separated from a stream of C8 aromatic compounds in the disclosed adsorption system.
