At present, environmental responsibility of industrial enterprises is one of important factors of reducing the environmental footprint. Many large companies stake on implementing breakthrough technologies and novel concepts in key industrial processes to ensure reliable and safe operations.
One of environmental innovation case study was launching a new biological treatment station (BTS) of mixed domestic and industrial water runoff at Sokur line operation dispatcher station of Transneft Western Siberia in Novosibirsk region.
Interim Chief Engineer of the Company Dmitry Khrychev shared that a new mechanism of combined treatment of industrial and utility runoff is used at the new operating facility. This allows optimization of the runoff treatment by excluding the equipment envisaged in standard treatment methods.
Furthermore, this enables to enhance the performance of treatment works and radically reduce the number of staff engaged in the station maintenance. Thus, only two employees - foreman and shift operator - keep track of the BTS proper operation.
The “smart” modern microprocessor-based automation system constantly monitors and checks the station’s process equipment. Information about any emergencies is immediately sent to operator’s automated workstation, which allows instantaneous elimination of any malfunction.
The station was built to treat effluents from several industrial facilities: Sokur LODS, Sokur PS as well as an industrial-technical maintenance and furnishing section at Novosibirsk Regional Oil Pipeline Directorate.
All industrial and storm runoffs pass six treatment stages: from mechanical to UV decontamination and disinfection. Furthermore, innovative technologies are used in the treatment process: coalescent module and floating bio load bioreactor. In this bioreactor water is mixed with special silt containing microorganisms which absorb the remainder of petroleum products. This allows maximum possible cleansing of runoffs from nitrogen compounds, nitrites and nitrates.
This certainly enables almost complete rejection of chemical agents in the treatment process.
The biological treatment station was launched at the end of last year and has proven its worth and efficiency during several months of operation. After their treatment the runoffs fully comply with strict standards and requirements for their further dump into fishery waters.
It should be noted that Transneft Western Siberia is one of the first Transneft subsidiaries to build such a station. This innovative project was part of the Programme for integrated revamping of onsite facilities, implemented by Sokur LODS.
As of today, the given pumping station is one of several industrial facilities where the Company introduces most promising and advanced technologies.
It is here at Sokur LODS that construction is under way on a vapour recovery system that will enable to catch 100% of hydrocarbon vapours in the process of railway loading of petroleum products, condensing and returning them to the
Effective environment conservation solutions are also used in building a new tank farm: tanks are outfitted with aluminum floating roofs which maximally reduce petroleum product vapours emission in the process of tank operation.
“One of our undisputed maxims in relation to the environment is “doing no harm”. Being committed to our key mission of uninterrupted transportation of oil and petroleum products, we also make strenuous effort to conserve a unique nature of the regions where we operate. Therefore, minimization of environmental footprint, tightening of environmental standards is an important part of Transneft Western Siberia’s business processes. The annual revamping of existing industrial capacity and equipment, optimization and introduction of resource saving and environment conservation technologies is one of our top priorities. In the previous year alone the Company’s actual spending on environment conservation roughly amounted to RUB 1 billion,” Mr. Khrychev pointed out.
