The erection of SIBUR maleic anhydride (MAN) production facility, licensed by CONSER, is progressing swiftly at the construction site of Tobolsk, Russia. The project execution begun at the end of 2018 under CONSER supervision, and, despite the slowdown due to the global pandemic of Covid-19, the start-up of the first MAN Plant in Russia is expected at the end of 2021. "Now all the main equipment: columns, tanks, pumps, heat exchangers and fans - is at the construction site and is being installed in accordance with the schedule" the press service of SIBUR's Tobolsk enterprises reported last November 2020.

Steel structures and up to 80% of equipment are Russian-made. Specific units and assemblies that are not yet produced domestically, including the main synthesis unit, have been ordered abroad.“You cannot buy specific equipment for MAN production in Russia,” says Vasily KAZAKOV, head of maleic anhydride production. “SIBUR is a pioneer in this topic, nobody produces MAN in Russia yet”. The key piece of the Plant – the MAN Reactor - arrived in Tobolsk last August 2020. The Synthesis Unit - 7.5 meters high, 9 meters in diameter and weighing 600 tons -, in which the main reaction of butane oxidation will take place, was assembled by MAN Energy Solutions in the German city of Deggendorf. From there, the equipment was delivered to Antwerp, then along the Northern Sea Route to the port of Sabetta, and the last segment of the route to the Tobolsk industrial port it covered along the Ob and Irtysh. Finally, the transportation of the oversized equipment from the industrial port to the construction site was managed by NIPIgaspererabotka – the leading Russian company engaged by SIBUR for the MAN Plant engineering services.In total, after travelling about 5000 kilometers, the process of delivering the oversized cargo to the construction site took about three months.

The MAN production capacity in Tobolsk will amount to 45 thousand tons per year. The finished product at the plant will be produced in two phases - liquid, which is then transported to tank containers, and solid, formed into briquettes or pastilles. 

Currently, maleic anhydride is not produced in Russia. The demand on the Russian market is 6 thousand tons per year, which is covered by imports. SIBUR expects to completely cover the import of maleic anhydride and to establish its export supplies to the markets of Europe and Turkey. Maleic Anhydride is widely used in various fields from automotive and shipbuilding to pharmaceuticals. It is used in the production of films, synthetic fibers, varnishes and paints, as well as in the food industry (malic acid is derived from maleic anhydride). 

The Italian process licensing company CONSER became the licensor of the MAN production technology, whose technical solutions, as a result of the analysis carried out by SIBUR, were selected as the most advanced and environmentally friendly, having at the same time the lowest production cost. In fact, CONSER technology features, such as the high efficiency of the absorption process and the off-gas recycle, allow to reduce the consumption of raw butane feedstock and to increase the production of maleic anhydride. Moreover, like other petrochemical plants of SIBUR in Tobolsk, the MAN plant will have a closed production cycle, and thus any possible negative impact of production on the environment and human health will be minimized.
