TANK HEATER Russian patent published in 2022 - IPC B65D88/74 B65G69/20 

FIELD: viscous hydrocarbons transportation and storage.

SUBSTANCE: invention relates to the transportation and storage of viscous hydrocarbons and can be used at petrochemical facilities, oil refining and pipelines. The tank heater is made in the form of a multilayer flexible coating and contains thermal insulation (1) on its outer side, and further inland there are electric heating elements with a dielectric coating (2), then a layer of magnetic substance (3), in which containers are built in the form of strips of flexible polymer material containing a saline solution capable of exothermic and endothermic controlled reactions. A multi-layer flexible coating is placed on the surface of the tank, after which a layer of magnetic substance is tightly fixed on the steel wall. Before the electrical energy is applied, an exothermic reaction of the brine solution is started in the flexible containers, which becomes solid, creating a solid containment loop around the steel container. After a controlled endothermic reaction, the solid in the flexible containers goes back into the liquid fraction and is ready for a new cycle.

EFFECT: invention increases the reliability of fixing the multilayer flexible coating on the complex relief surface of the tank car and makes it possible to reduce current operating costs in cold weather, improve the safety of workers.
