The Rısks Assocıated wıth the Transportatıon of Hıgh Vıscosıty Oıls by Heatıng

Most of the world's natural resources consist of ordinary and high-viscosity oil. High-viscosity and heavy oils can be transported by tanker, pipeline or rail. However, they lose their flowability at a certain temperature. Proper control of the movement of the contact zone of oil products is essential for successful sequential transportation. Increasing the temperature of crude oil reduces its viscosity and improves its flow during pipeline transportation. The rheological composition of the oil determines the efficiency of transportation in the main pipeline. Heavy oil contains high percentages of tar, paraffin and asphaltene. These components play an important role in increasing the oil's viscosity. One of the most popular methods involves the addition of chemical inhibitors to heating methods. The transportation of heavy and paraffinic oils by pipeline includes dilution and emulsification, as well as annular and main flow, and heating via thermal, electrical (direct or indirect), solar and thermochemical systems. However, the suitability of these techniques depends on the characteristics of the crude oil, new technological developments, and the results of feasibility studies. Although transporting high-viscosity oil by heating is technically and economically efficient, this process is accompanied by a number of serious risks. The most significant of these are fire and explosion hazards, mechanical damage to pipelines due to temperature stress, environmental pollution and energy loss. Therefore, high safety standards must be maintained when transporting oil by heating, and modern insulation and monitoring systems must be used. Only in this way can technical reliability and environmental safety be ensured.
