The Polyethylene Plant (PE)

Designed Capacity: 300 KTA
Technology: Nova Chemicals, Canada

The Polyethylene Plant (PE) uses Sclairtech Technology licensed by DuPont
(Novachem) of Canada. The Swing-Plant was built by Kobe Steel of Japan and is capable
of producing both High and Linear Low-Density categories of Poly Ethylene. Ethylene is
the raw material for PE plant and it comes from Olefin Plant.

High density and Low-density particles grow in reactor at polymerization step, where
monomer, ethylene and solvent, cyclohexene is combined with co monomers, Butene-1
and catalysts and co catalyst. Unreacted catalyst is removed from the polymer and then it
process through the extrusion to get the PE pellets. Then these polymer pellets are
transferred to warehouse for bagging. The unique feature of this process is the ability to
swing from High to Linear Low and vice versa in short spans of time.
