Organization of transportation by tank cars of solidified petroleum fuels with transmission through field pipelines in low temperature conditions

Abstract

The method of unloading and reloading solidified oil fuels, with the use of pipelines made according to temporary technological schemes, produced in winter, is considered. Cooling of solidified fuels is accompanied by a sharp increase in their viscosity, which makes pipeline transmission impossible. In fire hazard, it is proposed to produce continuous heating of the pumped fuel using devices based on low-temperature combustion of propane-butane mixture on the surface of the catalyst carried out at fire-safe temperatures. It is also proposed to install a temporary heat-insulating shell on the pipeline that meets the operating modes of the heaters.

New ways to improve the efficiency of railway transportation of viscous petroleum products

“…It can be concluded that when TGC is suppressed, a liquid petroleum product will cool down as a quasisolid body by molecular thermal conductivity at λ VPP of about 0.12 W/m°C, and the temperature distribution in it will correspond to the picture shown in Fig. 2 [16][17][18][19][20][21][22][23][24][25][26][27].…”

“…Options for the use of tank wagons with a steam heating casing and tanks for light general-purpose petroleum products are being considered [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”
