Jam Petrochemical’s production site is a large olefins and polyolefins complex located in the Pars Special Economic Energy Zone (PSEEZ) at Assaluyeh, Bushehr province, on Iran’s Persian Gulf coast. The site benefits from direct access to PSEEZ port and pipeline infrastructure, enabling feedstock supply from South Pars and bulk exports of polymers and chemicals to regional and Asian markets, while its clustering with other complexes in Assaluyeh supports shared services, logistics and utilities.

The complex occupies about 77 hectares (with an additional 22 hectares reserved for phase‑2 expansions) and was developed under NPC’s “Olefins 10” program to process ethane and other fractions from the South Pars gas field into higher‑value petrochemicals. It houses multiple integrated units, including an ethane steam cracker, HDPE and LLDPE plants, butadiene and butene‑1 units, and associated utilities and storage, making it one of Iran’s largest olefin hubs and a major exporter of ethylene, polyethylene, propylene and related products.

Production Capacities

NPC summarizes Jam Petrochemical Complex as having a total nominal capacity of 3,079.5 kt/y of petrochemical products across its integrated olefin, PE and C₄‑derivative units, on a site area of 77 hectares plus 22 hectares for phase‑2 development. The complex was founded in 2000, with major process units commissioned over 2007–2012 as follows:

Cracker Feed

A project to increase the capacity of the steam cracker by 15% was completed by mid 2019. The Jam Petrochemical olefin plant, was already the largest in Iran at 1,320 ktpa ethylene, but is assessed to have increased to around 1,500 ktpa ethylene in size. The unit started up in 2008 and has approximately 50% of its ethylene production tied to ethane. The steam cracker also processes other NGL and liquid feedstocks." 

Input feeds for the complex are summarized by NPC:
