Preventing Emergency Shutdown in a Low-Density Polyethylene Reactor

Low density polyethylene (LDPE) is produced continuously in tubular reactor under high pressure conditions at this European polyethylene plant. To keep the rate continuous, the goal is to reach constantly high throughput and operate the process under secure conditions. After the reactor has been shut down because of cleaning, it is restarted under safe conditions. Ideally, this start-up is performed as fast as possible to avoid downtime.
