Vertical Steel Structure

The steel structure consists of a wall, a roof, and a base. Tanks are manufactured and assembled using both roll-up and sheet-by-sheet assembly methods.

Insulation

To reduce heat loss and maintain the temperature regime, a layer of insulation made of galvanized steel with a protective casing is provided.

Loading System

Allows top loading of oil products. The inlet is positioned above the maximum level. The entire system is installed inside the tank. The chute prevents oil product splashing during loading.

An electric actuated gate valve regulates the feed; it is remotely controlled by a signal from the control cabin.

Drainage Device

The drainage device is designed to drain the tanks and discharge the remaining product at the bottom. It consists of a pipe line and closing valves.

Tanks are emptied through an electric actuated gate valve that is remotely controlled by a signal from the control cabin. A closing valve is provided for manual control.

Side Agitator

The side agitator is designed to homogenize the heavy oil stored in the tanks. The device consists of a three-blade mixer shaft operated by a gear motor.

The mixer is mounted vertically at a 90° angle to the tank.

The shaft outlet seal is provided by a mechanical seal.

Heating System

The product is heated to the required temperature with oil heating sections located at the bottom of the tank. Each heating section consists of a support frame and pipe structure. The number of sections depends on the tank diameter.
 

Oil Distributor

The oil distributor is designed to evenly distribute the heat transfer fluid to the tank heaters. It consists of the following components:

• Heat transfer fluid supply and return pipes
• Brackets for tank mounting
• Closing valves
• Temperature and pressure sensors
• Operation of each heating section can be manually or automatically stopped. In automatic mode, the tank heating can be remotely stopped using an electrically operated control gate mounted at the outlet of the return manifold.

Steam Relief Device

The steam relief device consists of a vent pipe and a steam shut-off valve.

Emergency Overflow Protection

In case of automation failure, when the maximum emergency level in the tank is exceeded, the product is discharged to the emergency tank via a special pipe.

Control Cabin

The tank is equipped with a local control cabin. The cabin, integrated into the control system either on-site or remotely, provides the ability to monitor and control the instrumentation.
