Power Generating & Energy Saving

Key energy-saving measures:
  • Reducing electricity consumption by pumps, air cooling devices, transformer substations and compressors through the installation of energy-saving equipment, including frequencyadjusted drives;
  • Increasing thermal exchange processes and more complete fuel combustion in furnaces;
  • Optimizing the recovery system during primary crude refining, and using secondary energy resources;
  • Using energy-efficient submersible centrifugal pumps (UENTS);
  • Optimizing the operating regimes of submersible equipment and booster pumps.

The Company has also initiated programs to develop power generating infrastructure and rational use of energy as part of Gazprom Neft’s strategy of production development, which involves launch of new industrial facilities and therefore increases energy needs. The work includes efforts to make internal and external supplies of electric power more dependable, and to increase the capacity of power generating units through modernization and technical improvement.

At the moment, Gazprom Neft is adoptinh energy-saving as its main strategy for reducing the share of energy consumption costs as a proportion of overall production costs. In this regard it is implementing medium-term programs of energy efficiency enhancement.

Gazprom Neft’s business units are currently implementing regular energy saving initiatives. The aim is to make such initiatives more systematic both in terms of technologies used for energy efficiency and also of the management resources required.

In 2011, the Company invested RUB 369 mn to finance project surveys, construction and installation work concerning upgrades to internal and external power supply systems at business units in the oil refining segment (see Table below).

Proactive energy-saving is a strategic priority for Gazprom Neft. The energy component in unit production costs at Company business units is being reduced through energy-saving activities as part of wider medium-term programs to raise energy efficiency.

Progress in these programs during 2011 is evident from energy savings worth RUB 771 mn and RUB 963 mn in the refining and crude oil production segments, respectively.

Key energy-saving measures are as follows:

  • Increasing thermal exchange processes and more complete fuel combustion in furnaces;
  • Reducing electricity consumption by pumps, air cooling devices, transformer substations and compressors through the installation of energy-saving equipment, including frequency-adjusted drives;
  • Optimizing the recovery system during primary crude refining, and using secondary energy resources;
  • Using energy-efficient submersible centrifugal pumps (UENTS);;
  • Optimizing the operating regimes of submersible equipment and booster pumps..

The Company is currently working on creating a permanent energy management system throughout Gazprom Neft. This will enable the transition from various one-off energy saving measures to a platform of systematic technology and management solutions.

The Company’s crude-oil production units work continuously to reduce atmospheric emissions, particularly by achieving higher levels of utilization of associated oil gas (AOG). The Company has a program to raise the AOG utilization rate to 95% by constructing gas-collection networks and facilities, including power generating facilities, that can use the gas.

Atmospheric emissions in the petroleum refining block have been consistently reduced thanks to environmental actions, which include retrofitting of production capacity, replacement of burners in plant furnaces, adding modern emission-reducing devices to tanks, and ensuring airtight seals when petroleum products are tanked. In October 2010, the Omsk Refinery commissioned an Isomalk-2 isomerization plant for light gasoline fractions. The complex is the largest in Europe, and enables production of a high-octane component for saleable gasoline with zero content of sulphur, aromatics and unsaturated hydrocarbons. Integration of the complex in industrial processes at Omsk has increased crude oil refining depth and raised output of high-octane automotive gasoline of environmental Classes 4 and 5. This plant was in operation throughout the year under review.

The Company’s petroleum product supply units have carried out comprehensive analysis of the environmental and economic impact of deploying systems at filling stations that can recover light petroleum product vapours.
