ПЕРЕВОЗКА ЖЕЛЕЗНОДОРОЖНЫМ ТРАНСПОРТОМ ВЯЗКИХ НЕФТЕПРОДУКТОВ В ЗИМНИХ УСЛОВИЯХ ПРИ ПРИМЕНЕНИИ ПРИНЦИПОВ КАТАЛИТИЧЕСКОГО РАЗОГРЕВА

Abstract

The article investigates the problem of unloading solidifying petroleum products (such as boiler fuel oil) at a medium-capacity drain site. It is accepted that a filling train of 45 specialized 67-ton tank cars is placed under the drain, the train is en route for 7-8 days at negative air temperatures (up to -20 °C). Usually, from 3 to 5 tank cars are simultaneously put under unloading at a medium-capacity drain site, up to 10-12 hours are spent on heating them; for unloading, emptying the drain site and installing the next 5 tank cars - 2-2.5 hours more. The rest of the tank cars are put on the access roads, waiting in line. The oil product in them, initially having a low temperature, keeps cooling and passes into a highly viscous state. In addition to the delivery time (7-8 days), the train, as a rule, is under the unloading operation for 8-10 more days. In the method of processing proposed by the authors, tank cars can be heated already at the idle stage on the access roads, and the discharge is carried out at the drain site. In this case, the unloading time of the filling train is reduced to 15-20 hours.
