Abstract: A polyolefin reactor flashline heater system may include an enclosure, a heating section, and a transformer. The heating section is contained in the enclosure and extends between a first end and a second end. The first end is fluidically coupled to a polyolefin reactor product inlet. The second end is fluidically coupled to a heated product outlet. One or more pipe sections are coupled in series between the first end and the second end. The one or more pipe sections are formed of an electrically conducting material and have a predetermined diameter to transport a polyolefin reactor stream from the first end to the second end. The transformer is electrically coupled to the first end and the second end and configured to heat the heating section by impedance heating. A polymerization system may include a polyolefin reactor coupled to the polyolefin reactor flashline heater system.
