Air protection measures

The Company has a well-developed production infrastructure for associated petroleum gas utilization: 23 gas turbine power plants and seven gas reciprocating engine power plants which use APG for power generation. Along with the construction and operation of the small-scale power generation facilities, «Surgutneftegas» PJSC successfully implements other ways of rational use of APG. Associated petroleum gas is used at the gas processing plant in Surgutsky District, is injected in oil bearing horizons to maintain reservoir pressure in the Republic of Sakha (Yakutia), is used in all the areas of the Company’s operations as fuel for boilers, furnaces, initial water separation units, etc.

In order to diminish air pollutants emission to the atmosphere, the Company carries out measures on reduction of emissions during the periods of adverse meteorological conditions, reductions of hydrocarbons losses, improvement of energy efficiency of production. Operating setup of fuel-fired equipment is performed, operational effectiveness of gas treatment units is controlled, their inspection, current repair and overhaul are carried out on a regular basis. Environmentally friendly fuel is used, motor vehicle fleet is renewed, fuel efficiency of motor vehicles is increased. The Company keeps records of substances which destroy the ozone layer, transits the equipment to coolants which are safe for the ozone layer. Measures aimed at prevention of spills of oil and oil products are carried out. The Company performs industrial control of air pollutant emissions at all stationary and mobile units.

In 2017, a gas turbine power plant at the Yuzhno-Nyurymskoye field in Tyumenskaya oblast was put into operation, a network of gas pipelines was constructed. In 2018, the Company expects to construct the gas separation facility at the Rogozhnikovskoye field and low pressure separation compressor stations at the Yuzhno-Vatlorskoye field as well as more gas pipelines.

As the result of steady and constant carrying out of air protection measures, implementation of the program on construction and upgrading of APG utilization facilities, «Surgutneftegas» PJSC, over the years, demonstrates a sustainable mitigation of emissions of pollutants to the atmosphere. Emissions of pollutants are decreased by 5% (8.4 thousand tonnes) as compared to 2016.

Due to a high level of useful utilization of APG, «Surgutneftegas» PJSC annually prevents emissions of more than 30 million tonnes of methane and carbon monoxide greenhouse gas (in CO2-equivalent) into the atmosphere.

A comprehensive engineering and environmental approach to air protection challenges allows the Company to rationally use APG as a resource, valuable for construction process, supply energy to its own facilities, not to construct many kilometers of power lines.
