The Science and Technology Centre includes laboratories providing quality assessment services during the entire oil production and refining process.

Quality control process starts by field testing of the quality of crude oil in facility laboratories, it is continued with the testing of crude oil prepared for refining, the testing of quality of certain processes and intermediate products important for the monitoring and control of operation of refining facilities, and finishes with the quality control of the final refining products and the issuance of a Test Report. The Test Report confirms that the quality of produced fuels is in compliance with the quality required by the national rules and regulations.

Laboratory tests performed as the final quality control, prior to the delivery of fuel to end users, are undertaken in order to ensure the quality of fuel during the transport from the refinery to filling stations and to prevent possible degradation of fuel in transport. These procedures guarantee the quality of fuels produced by the Company.

Raising the level of customer satisfaction to the highest level possible is one of the Company priorities. In order to analyze and monitor customer satisfaction, the Company conducts different customer satisfaction surveys.

Communication between suppliers and customers requires producers and importers to provide information on the environmentally-friendly and safe use of their substances or mixtures – the main instrument in such communication is the Safety Sheet. The safety sheet is a statutory document whose use has been mandatory since 2013.

Compliance with REACH (Registration, Evaluation, Authorization and Chemicals) is a prerequisite for the export of Company products to the European Union. Since a significant part of its products is exported to the European Union market, NIS has undertaken extensive tests and activities with a view to fulfilling its REACH obligations. A total of 14 Company products have been registered as REACH-compliant. This has ensured free marketing and sales of NIS products on the European Union market. Read more

Minor negative impact of product

The Company particularly protects its consumers. In order to reduce environmental impact, NIS produces and sells AdBlue, a 32.5 percent aqueous urea solution used as an agent for reducing certain vehicle exhaust gases, notably nitrogen oxide, by converting it into the harmless gas nitrogen. Nitrogen oxides are hazardous both for the environment and human health. AdBlue is stored in a special vehicle tank, from which it is injected into the exhaust gas treatment device, the so-called SCR (Selective Catalytic Reduction) system.

The project for constructing the amine plant within the production complex of the Oil and Gas Preparation and Transport Unit in Elemir was commenced in September 2013 and implemented in 2016. All the necessary permits from state authorities were obtained for operation of the newly built plant, which will reduce CO2 quantities in gas produced in NIS to a level of 3 percent, corresponding to the technical requirements for its use in the national gas distribution network of Serbia. Operation of the new plant in Elemir enables harmonisation of gas quality for delivery to the transmission system, increases gas production and levels of efficiency of Company’s oil and gas deposits by maintaining deposit pressure and, additionally, protecting the environment.

The development of a product with commercial name NISOTEC KOMPRESOL PAG 150 is completed, and it is intended for the lubrication of industrial compressors of gas such as methane, ethane, propane, carbon dioxide, which is, due to its biodegradability, more than 60% environmentally more acceptable compared to other products with the same purpose. The biodegradability of this product originates from its base foundation made of polyalkylene glycols. Since September 2016, this NISOTEC product has been used for lubricating CO2 compressors in NIS Amine Plant in Elemir.
