Abstract

A process and a plant for producing a polyolefin obtained by polymerization of propylene; the process comprises: a reaction step, during which the propylene reacts in a polymerization reactor so as to obtain a said polyolefin; a stripping step, during which said polyolefin is contacted with a counter-current flow of saturated steam in a stripping device so as to strip away gases from said polyolefin; a purification step, which takes place at in a purification assembly and during which CO, CO<2> and alcohols are separated from said gasses so as to obtain a stream of treated gases; and a recycle step, during which the stream of treated gasses is fed to the polymerization reactor.
