| Zusammenfassung: | Title screen This paper presents the results of polymeric deposit analysis in HP recycling system on two ethylene polymerization trains in tubular reactors when using mixed initiation (organic peroxides and oxygen) in the process of various grade production. It is demonstrated that polymers belong to the very low density type (with ? in 0,860 to 0,900 g/cm3 range), due to ultra high branching. Consideration is given to known processes of that kind polymer production. There discussed the alternatives of different approaches to special process features found. It is stated that 80-year high pressure PE synthesis history has been keeping potential for the development. |
