Air protection measures

The Company has a well-developed production infrastructure for utilization of associated petroleum gas: 23 gas turbine power plants and seven gas reciprocating engine power plants which use APG for power generation. Along with the 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 decrease 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 units.

In 2018, the investments of «Surgutneftegas» PJSC in construction and technical reequipment of facilities for APG utilization amounted to 81.5% of the total volume of capital investments in construction of environmental facilities. The Company spent over RUB 2 billion on air protection measures. A network of gas pipelines, gas separation facility at the Rogozhnikovskoye field and low pressure separation compressor station at the Yuzhno-Vatlorskoye field were constructed.

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 21%, the rate of specific emissions of pollutants is decreased from 2.51 kilograms to 1.98 kilograms per tonne of produced hydrocarbons as compared to 2017. Due to a high level of useful utilization of APG, «Surgutneftegas» PJSC annually prevents emissions of more than 30 million tonnes of greenhouse gas (in CO2-equivalent) into the atmosphere.

A comprehensive approach to reduce a man-made impact on ambient air, preservation of natural ecosystems and rational use of natural resources allow the Company to significantly minimize the negative impact on the atmosphere as a result of production operations of «Surgutneftegas» PJSC.
