A closed-type flare is being installed at ZapSibNeftekhim with the utilization of 99.9% of hydrocarbons

ZapSibNeftekhim has started the installation of the first closed‑type flare on the site as part of the construction of a new polypropylene production facility, DGP-2, the company's press service reported. Such an installation eliminates the burning of gorenje flame and does not create thermal radiation to the outside, increasing the safety of the technological process and reducing the environmental burden.

The closed flare system includes 63 automatic multi-jet burners with wind shields. Due to the organized supply of air by fans, the flame is distributed into many mini—streams, which ensures smokeless combustion and almost complete utilization of residual hydrocarbons - the efficiency reaches 99.9%. To increase reliability, a backup protection system is provided.

The company notes that the introduction of closed flares is part of SIBUR's comprehensive environmental modernization: flare systems, local wastewater treatment plants are being updated in parallel, and air quality monitoring is developing. In 2025, more than 160,000 atmospheric air studies were performed at ZapSibNeftekhim alone, and no excess standards were recorded. The construction of the DGP‑2 in Tobolsk started in 2023, the total progress of the project exceeded 80%.

For reference:

ZapSibNeftekhim is the largest petrochemical complex in Russia, located in Tobolsk (Tyumen Region). It is a key asset of PJSC SIBUR Holding.

Specialization: Production of base polymers. The capacities allow to produce up to 2.5 million tons of products per year (1.5 million tons of polyethylene and 1 million tons of polypropylene).

Meaning: This is the largest investment project in the history of the Russian petrochemical industry, which allowed Russia to switch from importing polymers to exporting them.

Raw materials: The plant processes by-products of oil and gas extraction (CFLU), turning them into valuable polymers for medicine, construction, the automotive industry and the food industry.

Ecology: The project is designed according to international standards using a closed water supply system, which minimizes the impact on the environment.
