Reducing the level of harmful atmospheric emissions is a key focus of Gazprom Neft’s environmental policy, with the company implementing an extensive range of environmental programmes across all areas of its operations.
One of today’s most urgent problems — climate change — is connected to environmental emissions of GHG. Gazprom Neft is doing its bit to address this problem with a programme to increase the productive use of associated petroleum gas (APG) produced in oil production as well as concurrently implementing several major projects in this area.
Construction of a complex gas treatment plant (CGTP) is currently ongoing at the Novoportovskoye field, being developed by Gazprom Neft on the Yamal Peninsula, located in the Arctic Circle. APG produced here will be compressed, processed, dried and re-injected into productive strata. The gas plant’s design capacity stands as seven billion cubic metres per year.
A key project in the Noyabrsk region of the Yamalo-Nenetsk Autonomous Okrug concerns the construction of the Ety-Purovskaya compression station. APG — the volume of which increases in line with increasing oil production — will go through the
The company is putting in place an effective APG utilisation system in the Orenburg Oblast — the eastern section of the Orenburgskoye oil and gas condensate field having, already, been connected to the Gazprom Orenburg gas processing plant (GPP) by a
A 24MW-capacity GTPP has been brought into production at the Shinginskoye field in the Tomsk Oblast, using APG from the Zapadno-Luginetskoye, Nizhneluginestkoye and Shinginskoye fields. In addition to this, construction of a gas pipeline connecting the booster pumping pipeline station (BPPP) at the Urmanskoye field to Tomskgazprom pipeline infrastructure has already begun.
This forms part of a major investment project directed at increasing productive use of APG at the Urmanskoye and Archinskoye fields, as well as at assets at the Yuzhno-Pudinsky licence block, from where gas will be transported through the Tomskgazprom network to the CGTP at the Myldzhinskoye gas condensate field.
A range of technological facilities are due to be built in the next two years including, in particular, a vacuum compressor station at the Archinskoye field and another at the Urmanskoye field.
Gazprom Neft has implemented several major projects directed at reducing harmful atmospheric emissions as part of an extensive programme to modernise its oil refining capacity. The problem of “legacy operations” has practically been resolved at all of the company’s refineries — the wastes accumulated at various enterprises over several decades having now been liquidated.
More than 180,000 tonnes of wastes accumulated since 1938 have been disposed of and/or recycled at the Moscow Refinery over the last five years, freeing up 15 hectares of land, with new high-tech facilities — including closed-circuit waste treatment facilities — being built on the reclaimed land, resulting in the level of harmful emissions being reduced by 97 percent.
Part of the first stage of modernising the Omsk Refinery involved pumping out the contents of a pool of refinery sludge, present since the 1970s. Commissioning new treatment facilities at the plant will result in a
A further area in reducing manmade atmospheric impacts involves modernising oil-product loading and shipping systems. Construction of an automated 1.2-million-tonne-per-year-capacity facility for on-spot oil-product loading into railroad cistern (tank) cars commenced at the Omsk Refinery in 2017. The facility will be equipped with a modern carbon filtration system, allowing the reabsorption of up to 99 percent of petroleum-product vapours, allowing them to be returned to the secondary oil refining cycle.
Hermetic bitumen tanker filling technology has been introduced at the Moscow Refinery. Five automated precision oil-product loading facilities have been built at the YaNOS refinery between 2005 and 2016.
Gazprom Neft is implementing cutting-edge methodologies in environmental monitoring, including giving regulatory agencies and local residents access to information on the status of activities throughout its production facilities.
A comprehensive environmental monitoring scheme has been introduced at the Moscow Refinery, a central element of which includes an automated air quality monitoring (AQM) system tracking the impacts of production on the atmosphere. System sensors are installed at eight key facilities throughout the plant, with information from these transmitted to both the plant control room and regulatory state agencies. Data from this environmental monitoring system is accessible on the Moscow Refinery website as well as being displayed on a large LED screen — the “Econiformer” — installed nearby.
The “Ecoinformer” section of the Omsk Refinery website publishes air-quality data, as well as five key metrics — carbon monoxide, nitrogen dioxide, sulphur dioxide, hydrogen sulphide and phenol concentrations — impacting the environmental status within the plant’s sanitary protection zone.
An eco-analytical centre for ongoing environmental monitoring is in operation at the YaNOS Refinery, including two laboratories monitoring ambient air quality, sources of pollution, and waste and drinking water quality. The plant also has two mobile environmental monitoring laboratories, in addition to this.
As well as the immediate benefits of implementing its environmental projects, Gazprom Neft is working towards reducing environmental impacts by improving the quality of its products. A large proportion of harmful atmospheric emissions in major cities come not from industry and energy production, but from cars. In a megapolis such as Moscow, vehicles’ role here can reach 93 percent — which is about a million tonnes of emissions per year.
Gazprom Neft’s refineries have switched to producing gasoline and diesel fuels of the highest environmental standard, Euro-5, exclusively — well in advance of regulatory requirements in the Russian Federation. Euro-5 fuels are distinguished by their high level of purity, and their extremely low pollutant content — including their sulphur and benzene (coal naptha) content.
