Russia: PET Production Sibur to Expand Terephthalic Acid Plant in Blagoveshchensk
Sibur has announced the upgrade of their terephthalic acid production at the Polief Blagoveshchensk site to expand its annual capacity to 350,000 tonnes. The project seeks to improve the site’s production efficiency and environmental safety, the company said.
Blagoveshchensk/Russia — Terephthalic acid is used to produce polyethylene terephthalate (PET), a basic material for the production of polymer packaging for mineral water, dairy products, juices, sunflower oil, and products of the textile, medical and other industries. One of the reasons for the expansion that was mentioned in a statement published by the company, is the undersupply of the Russian terephthalic acid market. The project is scheduled for completion in 2019.
The general designer is GSE-Giprokauchuk, a Russian design institute. Russian contractors will be engaged for construction and commissioning works.
As part of the measures, eleven existing production facilities will be upgraded. The project is designed to modernize 150 units of core production equipment, and most of the ancillary equipment. A modern gas catalytic oxidiser and the upgrade of all gas emissions treatment systems is intended to cut emissions by half. Additionally, transition to rotary pressure filters would translate into 1.5 times lower industrial wastewater discharges from the terephthalic acid production, the company claims. Further benefits mentioned in the statement include the prevention of excessive evaporation into the atmosphere. After the reconstruction, vapour will pass through cooling systems before it is returned to the process flow, which improves the site’s energy efficiency.
