ErichHahn ST Advantages
Mobile tanks are designed for active heating and storage of heavy oil while maintaining its quality. Mobile tanks can also be used as process tanks in oil, gas, chemical, food, and other industries.
Why Long Term Storage Tanks
The tanks can be combined into a tank farm.
The steelwork is comprised of a wall, a roof and a bottom. Production and installation of tanks is carried out both by roll and sheet-by-sheet assembly method.
A heat-insulating layer covered with a protective sheath made of galvanized steel is provided to reduce heat loss and maintain the temperature regime.
The chute prevents the oil product from splashing during loading. The gate valve with electrical actuator regulates the feed; it is controlled remotely by a signal from the control cabinet.
Unloading device is designed to unload tanks and release product from the bottom residue. It comprises a pipeline and shut-off valves. Tanks are unloaded by means of a gate with electrical actuator that is controlled remotely by a signal from the control cabinet. Shut-off valve for manual control is provided.
Provides top filling of the oil product. The inlet is brought above the maximum level. The whole system is mounted to the inner part of the tank.The side agitator is designed for homogenizing heavy oil stored in tanks. The device is comprised of a shaft with a three-blade agitator driven by a gear motor. The agitator is mounted on the side of the tank, at an angle of 90° to the vertical. The tightness of the shaft outlet is ensured by a mechanical seal.
The product is heated to the required temperature by oil heater sections located at the bottom of the tank. Each section of the heater consists of a support frame and a tubular structure. The number of sections depends on the tank diameter.
Oil distributer is designed for uniform distribution of the heat transfer fluid to the tank heaters. It consists of two pipe distributers for the supply and return of the heat transfer fluids, brackets for attachment to the tank, shut-off valves, and temperature and pressure sensors.
Work of individual heating sections may be suspended either manually or automatically. In automatic mode, the tank heating can be suspended remotely, using an electrically operated adjustable gate that is mounted at the output of the return manifold.
Vapor extraction device comprises a ventilation pipe and a steam trap.
In case of automation failure when the maximum emergency level in the tank is reached, the product is poured through a special pipe into the emergency tank.
The tank is supplied with a local control cabinet. The cabinet allows you to monitor and control instrumentation on site or remotely, by integrating the cabinet into the APCS.
