METHOD OF PROVIDING FIRE EXPLOSION AND ENVIRONMENTAL SAFETY DURING OPERATION OF TANK FARMS FOR STORAGE OF CRUDE OIL AND PETROLEUM PRODUCTS Russian patent published in 2014 - IPC A62C3/06 

FIELD: fire safety.

SUBSTANCE: method of providing of fire explosion and environmental safety in operation of tank farms for storage of crude oil and petroleum products is proposed, comprising mixing part of the crude oil and/or petroleum products with a mixture of nitrogen and petroleum vapour coming through gas surge from the tanks, compression of the resulting vapour-liquid mixture with volumetric pump and its accumulation in the receiver when filling the tanks or during storage of crude oil and petroleum products during the growth of the pressure in the tanks, feeding under its own pressure of the accumulated mixture of nitrogen and petroleum vapour through gas surge to the tanks when emptying the tanks or when storage of oil and oil products when the pressure drop in the tanks, the additional supply to the tanks of nitrogen produced by the device of reproduction of inert medium, with the lack of accumulated mixture of petroleum vapour and nitrogen to fill the releasing space of the tanks, and also supply under its own pressure of the mixture of crude oil and/or petroleum products with the absorbed petroleum vapour from the receiver to the tanks as they are accumulated.

EFFECT: improvement of method.
