Notice in connection with the recent publications announcing restrictions to the supply of oil with an organochloride content over 1 ppm to refineries

Date of publication: 23 September 2019 Printable version

A number of spurious and unreliable publications have appeared in the last month, claiming that the processing units at refineries have been designed, as part of a modernisation process, to process oil containing no more than 1 ppm of organochloride compounds. However, the main projects to retrofit the refineries were implemented before 2015, when, in accordance with the GOST R 51858-2002 specification on ‘Oil: General Technical Specifications’ (entered into force by Order of Rostekhregulirovaniye N 212-st dated 16 August 2005), the legal limit for organochloride compounds in oil was set at up to 10 ppm.

This limit should have been taken into account by oil companies when implementing the programme to modernize and retrofit the refineries. Similar instructions on the mandatory application of the GOST 51858 requirements were included in the requirements specifications issued by Transneft (in accordance with the Decree of the Government of the Russian Federation No. 1039 dated 21 December 2009) for connecting refineries, including those undergoing modernisation.

Furthermore, oil that is supplied to the trunk pipeline system on an ongoing basis complies with current standards, but has a chemical content of organochloride compounds significantly exceeding 1 ppm. See for example our partnership with the major oil company Rosneft.

For eight months of 2019, Rosneft delivered 131.1 million tonnes of oil to the Transneft system with an average organochloride compound content of 1.7 ppm (figure for 2018: 1.6 ppm). At the same time, in certain regions (Orenburg Region, the Udmurt Republic, Bashkiria and Central Siberia), Rosneft-extracted oil is being delivered to Transneft’s infrastructure with an organochloride content of up to 4.0 ppm, which significantly exceeds the level of 1.0 ppm claimed by Rosneft in its extraction processes and is close to the upper guideline limit, which is around 6.0 ppm.

According to data for 2018, more than half of Rosneft’s total oil deliveries contain organochloride in amounts greater than 1.0 ppm.

Organochloride content of oil supplied by Rosneft to Transneft (2018 data):

It should be noted that the incident connected to the ingress of oil with increased organochloride content into the Transneft system did not affect the limits for the weighted average organochloride content of oil supplied to Rosneft’s refineries.

Organochloride content of oil supplied to Rosneft’s refineries:

It should be, therefore, stated that the materials published in the media are not only biased, but also factually inaccurate, when they claim that Transneft does not properly comply with the requirements of agreements for the provision of oil transportation services for 2019. The Company accepts and transports oil in accordance with the established GOST specifications and technical recommendations.
