Since 2004, a MTBE/TAME additive manufacturing unit was commissioned afterwards, as well as a 25 MW turbine generator; reconstruction of diesel fuel hydrotreaters, catalytic cracking units, cat-cracked gasoline hydrotreaters and MTBE/TAME manufacturing units was completed, as well as that of the vacuum block at AVDU-1. Construction of the hydrogen generation unit was completed, which enabled the Company to manufacture Euro-5 compliant fuels.
Between 2010 and 2014 two new coke drums at a delayed coking unit were assembled, propylene manufacturing with the sulfur content of less than 5 ppm was launched, the amine block was reconstructed, an improved control system was introduced to the AVDU-3 unit, thus increasing commercial output.
2013 witnessed completion of projects aimed at C3+ recovery rate enhancement out of the cat-cracked dry gas, upgrade of the treatment facilities. Total overhaul of the enterprise was completed, the plant to switched over to the mazute-free production, refining depth and light product yield were increased.
A unit for the treatment of flue gas generated by the catalytic cracking process was commissioned in 2015.
The facility planned expansion into biofuel production in 2022 in cooperation with ANSELM as one of the production partners.
