Linear Low-Density Polyethylene (LLDPE) Unit

The LLDPE unit of Jam Petrochemical Complex has been designed and implemented under the license of BASELL, with basic engineering by TECNIMONT, utilizing SPHERILENE technology. With an annual production capacity of 300,000 tons, this unit is one of the largest polymer production facilities in Iran, capable of producing both linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE). It has the capability to produce more than 60 different grades for a variety of applications.

The grades produced by this unit are classified into the following categories:

  • Injection Molding

  • Rotomolding

  • Stretched Tape

  • Monofilament

  • Yarn – Caps & Closures

  • Film

After preparation in the designated section, the catalyst is mixed with TEAL (for catalyst activation) and Donor (for stereoregularity control) and then fed into the pre-contact reactor. Once activated, the catalyst enters the first of four reactors (comprising two loop reactors and two gas-phase reactors). In these reactors, the catalyst reacts with a purified feed that has been completely refined in the purification section.

Following the polymerization reaction, the resulting powder is transferred to the steamer section to deactivate the residual catalyst and remove existing hydrocarbons through contact with steam. The powder is then dried using nitrogen in the drying section, stored in powder silos, and subsequently sent to the extruder, where it is blended with the required additives, pelletized, and packaged in 25 kg bags for market distribution.
