Amur Gas Chemical Complex: Navigating Technology Licensing Challenges

The Amur Gas Chemical Complex (Amur GCC) exemplifies the intricate balance between technological ambition and geopolitical realities. Originally designed to become the world’s largest polymer production site, the project has faced significant delays due to shifts in technology licensing dynamics, even as its core infrastructure advances.

The Amur GCC Project

Amur GCC stands as one of the most ambitious petrochemical undertakings in Russia’s recent history and a flagship of Russian-Chinese industrial cooperation. Located near Svobodny in the Amur region of Russia’s Far East, the project is a joint venture between SIBUR, Russia’s largest petrochemical company, holding a 60% stake, and China’s Sinopec, which owns the remaining 40%. When completed, Amur GCC will be among the world’s largest producers of base polymers, with a design capacity of 2.7 million tonnes per year—2.3 million tonnes of polyethylene and 400,000 tonnes of polypropylene.

The complex is integrated with the broader Amur gas processing and gas chemical cluster, ensuring direct feedstock supply via pipelines. Gazprom’s Amur Gas Processing Plant (Amur GPP), which processes natural gas from East Siberian fields, will supply the primary feedstock to Amur GCC: ethane (up to 2 million t/y), and LPG (propane/butane, ~1.1 million t/y).

Steam Cracker and Downstream Progress

At the heart of the complex lies its 2.3 million t/y ethylene plant, supplied and partially engineered by Linde before the German firm’s confirmed withdrawal in 2022. Linde’s contributions included delivering critical components like the 1,500-ton quench tower, transported from South Korea to the remote Amur site—a logistical triumph showcased in earlier project updates.

By January 2024, SIBUR released a progress video on AGCC status update as of December 2023, confirming that polyethylene (PE) and polypropylene (PP) production units were being deployed as originally planned. The footage shows equipment installation for these downstream facilities, suggesting that proprietary technologies from Western licensors—Univation (Unipol PE gas-phase plants), ChevronPhillips Chemical (PE slurry process, undefined if MarTECH Single Loop or Advanced Dual Loop), and LyondellBasell (Spheripol PP Technology)—remain integral to the project. This indicates that either licensing agreements persisted post-2022 or SIBUR/Sinopec retained rights to use the technologies despite licensors’ reduced involvement.

Licensing Uncertainties and Delays

While Linde publicly exited the project by July 2022, when part of the equipment, including the pyrolysis unit, had already been built, SIBUR and Sinopec decided to reconsider the strategy for implementing the project, redesigned it and replaced contractors and license holders for the polyethylene and polypropylene lines. To this date, the status of other Western partners remains ambiguous as public disclosures from SIBUR and Sinopec have not clarified whether CPChem, Univation, or LyondellBasell continue to provide technical support or if their pre-sanction contracts are being honored. The lack of explicit withdrawal announcements contrasts with the project’s two-year delay.

It is a matter of speculation if SIBUR and Sinopec may be relying on existing licenses, in-house expertise, or third-party intermediaries to proceed with the original technologies. The January 2024 video underscores that downstream unit construction aligns with initial designs, implying that the licensors’ intellectual property is still being utilized, albeit without confirmed active collaboration.

Construction began in August 2020 and mechanical completion has been delayed to 2026 (originally 2024–25). Despite licensing headwinds, the Amur GCC achieved 76% mechanical completion by mid-May 2025 with commercial polyethylene production to start by Q3 2026, polypropylene production and full operations expected to follow in 2027 (source: interfax.com).

Strategic Implications

The Amur GCC’s trajectory highlights the resilience of large-scale petrochemical projects in the face of geopolitical disruptions. While Linde’s exit created logistical and technical gaps, the continued use of Western-designed downstream technologies—whether through preserved licenses or workarounds—demonstrates SIBUR and Sinopec’s commitment to delivering a world-class facility. The complex’s success will hinge on operationalizing these units without direct licensor support, a challenge that could redefine global norms for technology transfer in sanctioned environments. For now, the Amur GCC stands as a testament to both international collaboration’s potential and its fragility in an era of shifting alliances.
