The effect of structural features of heat stabilizers during the cooling time of oil in a stopped oil pipeline

Abstract

According to the annual reports of oil companies, there is an increase in the production of high-viscosity and ultra-high-viscosity oil. At the same time, responsibility for the transportation of the product, which can occur under unsteady conditions and lead to emergency situations, is intensified. Thus, a forced shutdown of an oil pipeline during transportation of high-viscosity oil can cause the product to cool below critical temperatures, and further launch of the oil pipeline will be impossible. In this regard, the task of calculating the safe shutdown time of the oil pipeline has particular relevance. We have carried out a numerical study to determine the effect of the structural features of the heat stabilizer during the cooling time of oil in a stopped oil pipeline. The values of the cooling time of oil from the action of heat stabilizers, made by various manufacturers, were established. In addition, the effect of the length of the evaporation part and the installation distance of the heat stabilizer from the oil pipeline during the cooling time was studied.
