The most common production method of PE is through slurry or gas phase processing, and a few are produced by solution phase processing. All of these processes are exothermic reactions involving ethylene monomer, alpha-olefin monomer, catalyst system (possibly more than one compound), and various types of hydrocarbon diluents. Hydrogen and some catalysts are used to control molecular weight. The slurry reactor is typically a stirred tank or a more common type of large loop reactor in which the slurry can be circulated and stirred.
Polyethylene particles are formed as soon as ethylene and comonomer (as needed) and catalyst come into contact. After removal of the diluent, the polyethylene granules or granules are dried and dosed with additives to produce pellets. A modern line with large reactors with twin screw extruders capable of producing over 40,000 pounds of PE per hour.
The development of new catalysts contributes to improving the properties of new grades of HDPE. For example, two reactors in series producing products of significantly different molecular weights can produce bimodal molecular weight polymers with a broad molecular weight distribution.
