Sibur commissions 100,000tpa DOTP plant at Perm

Russian petrochemicals giant Sibur Holding has begun the commissioning phase of a project to manufacture the plasticizer dioctyl terephthalate (DOTP) at its site at Perm in the Urals region.

A new plant, which Sibur says will be Russia’s biggest producer of plasticizers with a scheduled annual capacity of 100,000tpa of DOTP, is due to commence production in the second quarter of this year.

The phthalate-free general purpose plasticizer is a key component of floor and roof coatings, wallpaper, cable compounds, and other construction products, ensuring higher strength, wear and cold resistance.

Russia is heavily reliant on the import of common plasticizers from Europe and the national market is currently facing a supply shortage of some 60,000tpa, according to Sibur. The arrival of the domestic plant will play a key role in Russia’s national import substitution programme.

As part of the project, Sibur had signed a technology licence agreement with the South Korean chemicals company Aekyung Petrochemical.

Sibur will provide the raw materials required in the manufacture of the site’s new plasticizer which is expected to allow Russia, not only to be self sufficient but also to export DOTP to neighbouring countries.

“At the Perm production site, we synthesize the main component of the raw material basket - 2-ethylhexanol. The enterprise infrastructure allows you to connect the new installation to the energy networks with significant savings in capital costs,” said the head of DOTP production Maxim Krotov last August.

A specialist team handling the commissioning process from December last was trained by the technology licensor Aekyung and will also oversee the release of the new product.

Sibur Holding chairman Dmitry Konov visited the DOTP plant construction site accompanied by the Perm Region governor Maxim Reshetnikov at the end of November (2018) when they jointly launched new biological water treatment plants at Sibur-Khimprom.

Reconstruction of the wastewater treatment plant, in an €8.5 million investment, was undertaken to ensure the high quality of wastewater treatment per year in excess of three million cubic metres.

The new facility will help to reduce the load being put on the wastewater treatment plants operated by the city authority in the nearby city of Perm providing extra capacity for municipal use.
