| Abstract: | In principle,polyethylene(PE) plants are so-called swing units which are able to produce both high density polyethylene(HDPE),medium density polyethylene(MDPE) and linear low density polyethylene(LLDPE),even if cost-wise it is better to avoid frequent switches between the PE grades with different densities.The processes of swing units including Sclair,Dowlex,Phillips,CX,Unipol,Innovene and Spherilene technology were reviewed in this paper.Unipol gas phase polyethylene production process is the most recently developed low pressure PE process and boasts many distinct advantages when compared with the commercial slurry and solution processes. |
