  • Process optimization of peroxide injection during polyethylene production
    Patent number: 6384153
    Abstract: In a process for the high-pressure polymerization of ethylene in a high-pressure autoclave or in a high-pressure tube reactor having one or more metering points for one or more peroxides, no peroxide or a reduced amount of peroxide is metered in during the time interval in which the pressure is lowered by opening a pressure maintenance valve and the original amount of peroxide per unit time is metered in again as soon as the pressure after closure of the pressure maintenance valve has built up again so that it exceeds 90% of the pressure difference between nominal pressure and lowered pressure.
    Type: Grant
    Filed: June 27, 2001
    Date of Patent: May 7, 2002
