METHOD OR SYSTEM FOR DESORPTION FROM ADSORBENT LAYER Russian patent published in 2014 - IPC B01D53/00 B01D15/18

Abstract RU 2514952 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. The method for desorption in an adsorbent layer involves passing a desorbent stream through an adsorbent layer lying in a removal zone to remove at least one nitrile compound and an oxygen-containing compound. After desorption, the desorbent stream is washed and combined with a raw stream for an alkylation zone after a selective hydrogenation zone.

EFFECT: invention enables to obtain a sufficient amount of a regenerating agent for desorption while minimising further expenses.
