Russia's Largest Petrochemical Plant Shut Down After A Drone Attack

Production has been suspended indefinitely.

The "Zapsibneftekhim" Plant "Sibura" in the Tyumen Region, Russia's largest petrochemical complex, which annually produces 2.5 million metric tons of polymers, as well as 40% of the country's total output of liquefied hydrocarbon gases (LPG) in the country, has halted operations following a drone attack, according to The Moscow Times.

The plant, located in Tobolsk and built between 2012 and 2020 with support from Germany’s Linde AG—and for which nearly $2 billion was allocated from the National Wealth Fund—halted production on August 10, three industry sources told Reuters. “The plant has been shut down indefinitely,” one of the sources told the agency. “An investigation into the consequences and damage is underway.”

As of August 11, the plant stopped selling propane-butane batches to the St. Petersburg Commodity and Raw Materials Exchange, which it had previously sold at a rate of 4,000 metric tons per day. According to Reuters sources, Zapsibneftekhim produces 6 million metric tons of LPG annually, half of which, however, it consumes itself to produce basic polymers. The plant employs more than 3,000 people.

On August 10, Tyumen Governor Alexander Moor reported a fire at an industrial facility in the region resulting from a drone attack, but did not specify which facility was targeted. OSINT analysts determined that the central gas fractionation unit (CGFU) at the plant—capable of processing 3.8 million metric tons of feedstock per year—was damaged. The plant’s total capacity is 8 million metric tons per year.
