Russia's Transneft says it did not add organic chloride to oil

The research unit of Russian oil pipeline operator Transneft said in a statement: * Organic chloride is used in the production of high viscosity oil

* It can only appear in pipelines with oil provided by oil companies - Transneft or its units do not add it to the system * It has a significantly corrosive effect on refinery equipment

* Organic chloride is dangerous at temperatures above 150 degrees Celsius * Transneft pipelines cannot be damaged by oil containing organic chloride as temperatures are 5 to 40 degrees Celsius.
