FIELD: separation.
SUBSTANCE: method can include a heating phase with subsequent cooling phase. Heating phase may include use of regenerating gas obtained from heating of treated recycled stream of polyolefin production process, for regeneration of dehydrator in device disconnected from system. Cooling phase can include thermosiphon circulation of regenerating gas, nitrogen, which does not contain diluent olefins or their combination in closed convection loop disconnected from system of processing device.
EFFECT: described are embodiments of a method for regenerating a dehydrator in a polyolefin disengaged from the system for processing polyolefins during production.
