Sibur has started the construction of a maleic anhydride (MAN) production facility at its site in Tobolsk, to become the first Russian company to supply the material locally.

The production plant will have a nameplate capacity of 45 kilotonnes per annum (ktpa) and is scheduled to go online in 2021, Sibur announced 14 Dec.

Maleic anhydride is used as feedstock in the manufacture of a variety of products including unsaturated polyester resins, films, synthetic fibres and oils, to be used in applications such as the construction, agriculture, automotive and pharmaceutical industries.

MAN improves the durability of end products, enhances their waterproof properties, resistance to temperature stress and mechanical impacts.

According to Sibur, MAN is currently not produced in Russia and domestic demand is covered by imports.

The local production of MAN, which Sibur said will be a high-margin venture, will allow the Russian company to monetise its own butane feedstock while “fully substituting” imports.

In addition to that, Sibur also sees potential for exports to western and eastern Europe as well as Turkey.

The new facility will be built in within the Tobolsk production site, in central Russia, and will tap into the existing infrastructure and feedstock flows at the site.

Italy’s Conser SpA has been selected as the licensor of the technology and NIPIgaspererabotka, a leading Russian centre for facility design, supply, logistics and construction, is developing the project engineering solutions.
