Air emissions
Key measures to reduce emissions of pollutants comprise:
- the renovation and construction of new generating capacities at electric power engineering subsidiaries, with improved automated systems for controlling fuel consumption processes and heat losses and minimizing emissions of pollutants
- replacing or upgrading equipment at industrial sites according to the principle of best available technology
- improving the technology used in systems to capture and treat pollutant emissions
In 2017 we achieved a reduction in emissions of pollutants, chiefly through building facilities that use APG, which effected a drop in flaring, as well as the relaunch of the Lokosovsky Gas Processing Plant after its refurbishment.
The reduction in specific emissions of pollutants by electric power engineering subsidiaries in 2017 was primarily due to a reduction in the share of fuel oil in the fuel mix at the steam and heat generation facilities of LUKOIL-Volgogradenergo. The slight increase in specific emissions in 2017 by petrochemical subsidiaries was due to a reduction in product output from Stavrolen.
