Biosphera environmental complex
Unique complex of biological treatment facilities for oil refineries
Establishing technological leadership
One of the key goals of the modernization of the oil refineries of Gazprom Neft PJSC is to enhance the eco-friendliness of the manufacturing of petroleum products. In 2017, the Moscow Oil Refinery commissioned the unique Biosphera complex of biological treatment facilities.
The complex has capacity for wastewater treatment of 1,400 m3 per hour with the ability for an increase to 2,000 m3 per hour under high power conditions. The water in the treatment plants undergoes multi-stage purification: mechanical, physical, chemical, and biological as well as filtration through a system of carbon filters and the removal of salts.
Wastewater treatment efficiency at the oil refinery rose to 99.9% as a result of the launch of Biosphera. Modern technologies provide a closed cycle of water consumption. Biosphera enabled the Moscow Oil Refinery to reduce the intake of river water by 60%. Roughly 75% of the treated effluents are returned to production, while the remaining water, whose quality is monitored according to 32 parameters, enters the Mosvodokanal system.
Concurrently with the commissioning of the Biosphera system at the Moscow Oil Refinery in 2017, the Company launched an even larger project to build a similar purification system at the Omsk Oil Refinery. The capacity of the new treatment facilities at the Omsk Oil Refinery will expand by 20% compared to the existing facilities and amount to 3,450 m3 per hour. The construction of the Biosphera facility will make it possible to reduce the area occupied by treatment facilities by more than 94% (from 159 to 9.2 hectares). The Omsk complex’s features include gas-convection chambers for cleaning off-gases and a nitrogen pad to prevent evaporation into the atmosphere.
