Abstract: A polyolefin manufacturing system and method including polymerizing olefin in a first reactor to form a polyolefin, transferring the polyolefin to a second reactor, polymerizing olefin in the second reactor, and discharging a product polyolefin from the second reactor. The system and method including operating the first reactor with a first reactor pressure relief system and the second reactor with a second reactor pressure relief system, both pressure relief systems to discharge to a flare system, and wherein a relief instrumented system (RIS) is configured to direct at least one process interlock that mitigates an excess reaction scenario as an overpressure relief scenario.

Abstract: A system and method for startup of a polyolefin reactor temperature control system having a first reactor temperature control path, a second reactor temperature control path, and a shared temperature control path. In some embodiments, during startup the second reactor temperature control path is configured to allow the temperature of a second reactor to rise due to the heat of the exothermic polymerization reaction occurring within reactor until reaching a predetermined setpoint temperature. In other embodiments, during startup a first reactor temperature control path is configured to include a heat exchanger used as a cooler, and a second reactor temperature control path is configured to include a heat exchanger used as a heater, to raise the temperature of the second reactor until reaching a predetermined setpoint temperature.
