Flow diagram showing LDPE production

In the high pressure polymerisation of ethylene, the fresh ethylene is used as the heat sink for the heat generated by the exothermic polymerisation reaction. The conversion to pol mier, at adiabatic conditions, is calculated with the following formula [Pg.41]

Conversion (%) = 0.075 (reaction temperature - ethylene inlet temperature). [Pg.41]

Reactor type tubular reactor autoclave reactor [Pg.42]

Mechanical dimensions inner diameter pipe 25 - 100 mm L/D 10000 - 50000 volume 250 -1500 litres [Pg.42]

Initiators oxygen and/or oi nic peroxides 0.2-0.5g/kgPE organic peroxides 0.2 - Ig/kg PE [Pg.42]
