Russia: Ramp-Up and Reconstruction Sibur Completes Terephtalic Acid Plant in Russia
Sibur’s Blagoveshchensk site has completed reconstruction of the terephthalic acid production facility, the only one currently in Russia
Moscow/Russia — Terephthalic acid (TPA) is a precursor to polyethylene terephthalate (PET), one of the world’s most widespread polymers that is used in the production of plastic bottles for beverages, synthetic fibres, various packaging, and medical supplies. TPA is also used to make eco-friendly plasticisers for toys, flooring and other products. In Russia, annual consumption of TPA amounts to around 500 kt. The increase in output from 272 to 350 ktpa by the upgrade of the existing capacities at Sibur's Blagoveshchensk plant is intended to decrease reliance on imports.
By integrating a new gas oxidizer, the project no longer requires natural gas, which reduces emissions by 50 %. The transition to rotary pressure filters will also translate into 1.5 times less industrial wastewater discharges from the terephthalic acid production. In addition, the new air cooling system is to almost fully prevent excessive evaporation into the atmosphere resulting from a significant release of heat during terephthalic acid synthesis. After the upgrade, vapour will return to the process flow, improving the facility’s energy efficiency multifold.
The project spanned from 2017 to 2019 and included upgrading more than 150 units of the core process equipment as well as most of the auxiliary equipment. The scope of key works covered eleven buildings on the production site. The general designer was GSE-Giprokauchuk, a Russian design institute. Over 40 Russian contractors were engaged to carry out construction, installation and commissioning works. A significant part of the equipment was sourced from domestic producers, including Volgogradneftemash, Tatneft Trade and Technology House, and Dimitrovgradkhimmash.
The company invested about $ 90 million in the project.
