PE Polymerization Techniques
The route to PE falls into two categories:
1. High pressure polymerization
• Produces LDPE
• Operating pressure ranging from 1000 to 3000 barg
• Operating temperature from 80 to 300°C
• Autoclave or tubular reactor
• Free radical catalysts using initiators (peroxides)
• Ethylene compression to the reaction pressure through several compression stages with inter stage cooling is a major step.
