Sibur has started construction of a maleic anhydride (MAN) production facility at Sibur Tobolsk in Russia.

Maleic anhydride is used in construction, agriculture, automotive, paint and varnish, furniture, pharmaceutical and other industries. It serves as feedstock for films, synthetic fibres, pharmaceuticals, detergents, fuel components and oils.

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

With a planned capacity of 45 ktpa, the facility is scheduled to go online in 2021.

MAN is currently not produced in Russia and domestic demand is covered by imports. Launching the high-margin MAN will enable Sibur to monetise its own feedstock (butane), improve the hydrocarbon processing rate in Russia, fully substitute MAN imports, and start MAN exports to Western and Eastern Europe and Turkey.

In addition, a Russian MAN production facility will provide new development opportunities for many domestic industries.

“We chose Conser as the licencor for the project thanks to its MAN production technology,” said MAN project manager, Vladimir Mishin.

“The secured approval of the design documents by the State expert review board and the results of the public discussions confirm the project fully complies with environmental laws and regulations.”

Sibur has engaged NIPIgaspererabotka, a Russian centre for facility design, supply, logistics and construction, to develop the project engineering solutions.

Russian contractors, including those based in the Tyumen Region, will be selected for construction and installation.
