REGENERATION OF DEHYDRATOR IN POLYOLEFIN PRODUCTION PROCESS CLEANER DISCONNECTED FROM SYSTEM Russian patent published in 2021 - IPC B01D53/00 

FIELD: chemistry.

SUBSTANCE: system for regenerating a cleaner in a polyolefin production system, comprising a purifier disengaged from the system, in which the first portion of the regenerating stream is supplied and regenerating the dehydrator in the purifier disconnected from the system to obtain a regenerated outflow, wherein the regenerating stream comprises a regenerating medium, and the regenerating effluent comprises a regenerating medium, water and an admixture; settling tank, in which at least part of regenerating outflow is supplied with obtaining of regenerating flow and water flow, besides, water flow contains water; and a stripping device into which a second portion of the regenerating stream is fed to produce an impurity stream and a process recycle stream, wherein said impurity stream contains at least a portion of the impurity, and process recirculated flow contains regenerating medium of second part of regenerating flow.

EFFECT: disclosed is regeneration of a dehydrator in a polyolefin production process disconnected from the system.
