Preserving quality and quantity of a product is an important task during the operation of tank farms. This requires maximum sealing of all processes of pouring, discharging and storing. Tanks have the largest share of evaporation losses throughout the course of the oil flow from fishing to refineries, at factories and petroleum product pipelines from factories to consumers. The process of storage of oil and petroleum products is combined with other technological operations (desalting of oil, heating, dehydration, mixing, etc.).
One of the most important methods of saving fuel and energy resources, which occupy a leading place in the development of the economy, is the fight against oil products losses. The issue of product losses due to the lack of equipment and the durability of its use is important. One of them is a receiving and distributing device, which is installed in vertical steel tanks.
To compare two of the most common variants of the execution of the disengagement body of the (ПРУ що це таке), a simulation of the process of pouring the product into the reservoir was performed using the Ansys 19.1 program. This made it possible visually to see how the receiving and distributing device works and what its efficiency can depend on. From the model of pressure distribution to the wall of the case (ПРУ) it is evident that when smoothly turning the housing, the pressure is distributed more evenly, due to which the load on the corner and the entrance to the receiver-distributing device in the wall of the tank will be less than when turning with the insert.
In this article an analysis of the possibility of improving the outdated technologies and the use of the latest in the storage of petroleum products is given. The use of a receiving and dispensing device can significantly increase the inter-cleaning period during the operation of the reservoir, as well as reduce the amount of work when cleaning the reservoir. This will reduce the level of dead remains, improvement the service life of the lower belt and the bottoms of vertical steel tanks, by reducing the zone of corrosive activity of the bottom sediment.
