Prevention of fire hazard situations on oil pipelines subject to the formation of asphaltene-resin-paraffin deposits

The article discusses the problem of ensuring fire safety at pipeline transport facilities for hydrogen sulfide-containing oil and oil and gas condensate raw materials, which during operation are subject to the formation of asphalt-resin-paraffin deposits. The effect of intensive accumulation of oil deposits on corrosion processes and the effectiveness of inhibitor protection has been established. To ensure fire and environmental safety in the oil and gas industry, it is critical to prevent local corrosive damage to oil pipelines. In modern conditions, the chemical method of removing asphalt-resin-paraffin deposits is one of the most promising. The paper proposes a new solvent composition for sediment removal. A fire risk assessment was carried out on the section of the main oil pipeline, during which an excess of the established standard value of the individual risk during local corrosion destruction due to untimely removal of asphalt-resin- paraffin deposits was revealed. A regression model was developed to assess the fire risk on the oil pipeline with the required volume of deposits solvent and its solvent capacity.
