Russian oil company Bashneft will use GE’s (NYSE: GE) ZeeWeed membrane bioreactor (MBR), electrodialysis reversal (EDR) and reverse osmosis (RO) technologies for therapy of refinery wastewater from the Bashneft-Ufaneftekhim oil processing advanced and other enterprises of the Northern Industrial Block of Ufa. Strict discharge laws, and the necessity to reuse the handled water, led Bashneft to decide on GE’s expertise for its new wastewater remedy plant.
A successful pilot research of different technologies was performed by GE in cooperation with Bashneft and State Unitary Enterprise—Institute of Petroleum Refining and Petrochemistry of the Republic of Bashkortostan in April-July 2013, which demonstrated technological feasibility of refinery wastewater purification in compliance with the strict requirements of environmental laws of the Russian Federation. Based mostly on the pilot’s performance and additional techno-economic calculations, Bashneft has chosen GE’s MBR, EDR and RO as the core technology of the modernization challenge for a biological treatment plant (BTP) of the Bashneft-Ufaneftekhim branch. To proceed improvement of the BTP design, Bashneft awarded GE the fundamental engineering contract for all of the principle technological tools and processes.
“Bashneft focuses on defending the environment from harmful industrial impacts. We imagine that the company’s oil processing advanced has to have one of the best wastewater remedy system, stated Alexander Korsik, president and chairman of the administration board, OJSC Oil Processing Joint-Inventory Firm Bashneft. “We see that GE’s superior technologies demonstrated performance will help to unravel this problem and make the water of the Belaya River cleaner, which will probably be helpful for all of the folks of Bashkortostan. /p>
In the framework of the project, GE will use ZeeWeed MBR know-how, EDR, RO and ion exchange sprucing technologies. Cutting-edge purification strategies allow implementation of water reuse and the minimization of water intake necessities. A distinctive feature of purification primarily based on the GE technological course of is the absence of main clarification tanks and secondary clarifiers. At the exit from the aeration tanks, the activated sludge is separated from treated water using ZeeWeed 500 ultrafiltration membranes. Waste solids dewatering is carried out on compact centrifuges. All of the above make it doable to scale back the world of purification facilities and exclude any chance of contaminant launch into the setting.
“GE is happy to supply progressive applied sciences that can assist Bashneft tackle its tough-to-treat water challenges. The performance of our applied sciences was proven in the course of the pilot examine earlier this year, and we stay up for continuing our help of Bashneft’s projects. We are assured GE’s role in the upgrade of Bashneft’s water remedy services will demonstrate a step ahead in sustainable improvement for all of Russia’s oil industry, stated Heiner Markhoff, president and CEO—water and course of applied sciences for GE Power & Water.
Biological Therapy Plants at the Bashneft-Ufaneftekhim Branch
Biological remedy plants of the Bashneft-Ufaneftekhim department had been commissioned in 1958. All industrial effluent, storm water and utility fluids from three oil refineries of Bashneft, OJSC Ufaorgsynthez, the Cherkassy pumping station, the Promoborudovanie plant and Novo-Alexandrovka residential neighborhood go to the BTPs after preliminary mechanical treatment. Reconstruction of the BTPs was carried out in 1983.
In compliance with an settlement between the Federal Supervisory Natural Sources Management Service of the Republic of Bashkortostan and OJSC Ufaneftekhim on December 26, 2010, by December 2011 the feasibility examine for BTPs modernization was prepared. In 2012, a contract was executed for engineering the modernization of BTPs with USE Institute of Oil and Petrochemical Refining of the Republic of Bashkortostan.
