Slurry polymerization process
Webb18 jan. 2011 · In this paper, an industrial linear low density polyethylene (LLDPE) production process including two serried fluidized bed reactors (FBR) and other process equipment was completely simulated in steady state mode. Both of FBRs were considered like two serried continuous stirred tank reactors (CSTR). In this simulation, a kinetic model that is … Webb3 dec. 2024 · Simulation of Slurry phase HDPE reactor High density polyethylene is produced by polymerizing ethylene (HDPE) and in cases co-polymerizing with propylene and 1-butene to achieve the desired density and properties. Hydrogen is also used to control average molecular weight of the polymer.
