Storage tank containers and tank farms

storage tank containers in combination as a battery tank farm

Our storage tank containers are generally used for storing fuels as well as chemicals. We also produce specialized storage tank containers for storing kerosene, crude oil, heavy fuel oil, transformer oil, or urea.

The majority of storage tank containers are based on international ISO dimensions as high cube tank containers (20ft-HC / 40ft-HC).

Recently, Krampitz has received an increasing number of orders for oversized containers with a volume of 75.000 to 96.000 liters. These containers are produced under the system names "KTD-F-75" and "KTD-F-96". They are 3.000 mm wide, 12.000 mm and 15.000 mm long respectively, and have a high cube height of 2.900 mm.

For large storage volumes exceeding 50.000 or 100.000 liters of a medium, we combine several tank containers of the same size to form a tank farm. For total volumes up to 500.000 liters, we use the 40ft HC-Minotaur series; for volumes exceeding 500.000 liters, we use the 50ft KTD-F series.

A large tank farm consists of a centrally located container and up to 10 universal storage tank containers with special tank farm equipment. Five storage tank containers are installed on each of the two long sides of the central container.

The central container – structure and function

The central container has a large, double-walled receiving and output tank in the middle. The receiving/pump section is integrated on one end, while the output section is located on the opposite end.

The pump section is equipped with two 1.000-liter pumps (1.000 liters per minute delivery rate). The pipeline routes for filling the storage tanks with fuel and for extracting fuel from the storage tanks are also electronically controlled via a central control unit.

The selection of storage tank containers is automatic via the central control system , which opens or closes the installed motor valves on the selected storage tanks. The fill levels of the individual container storage tanks can also be accessed via the central control system.

The pump section contains a 4-inch dry coupling to which the tank trucks connect upon delivery . The transfer pumps then use this coupling to draw the fuel from the tank trucks and transfer it to the receiving tank.

The dispensing section is equipped with a 2-inch loading arm for flow rates up to 500 liters per minute and a 1 1/2-inch hose reel with a dispensing nozzle for delivering 150 liters per minute to vehicles. A fuel dispenser can also be installed for dispensing control.

The following pump switching paths are possible:

Convey from tank trucks directly into storage tank containers
Pump from tanker truck into day tank
From storage tank container to tank truck dispensing section (deliver 150 gallons / 600 liters)
From storage tank container to tank truck dispensing section (deliver 300 gallons / 1200 liters)
From day tank to tanker dispensing section (deliver 150 gallons / 600 liters)
From day tank to tanker dispensing section (deliver 300 gallons / 1200 liters)

The battery storage tank container – structure and function

The battery storage tank containers are installed on both sides of the central container, with up to five units on each side. With a maximum suction line length of approximately 20 meters horizontally, the centrally installed transfer pump can operate smoothly without suction problems (cavitation). Of course, the piping system must be primed by pouring water during initial commissioning. After that, the pumps operate without any issues.

A niche is integrated into the end wall of the battery storage tank . This niche accommodates the filling and suction manifolds, which are routed through it. These manifolds hydraulically connect all storage tanks to the central unit.

From these collectors, connecting pipes run via T-fittings to the respective storage tanks , which are equipped with electric motorized ball valves. These motorized ball valves are controlled by the central control unit of the central container. The central control unit allows the operator to select the respective tank for filling or emptying.

A central control module , which works in conjunction with the central control unit, is installed in the niche. This contains the electronic overfill protection for the tank, the evaluation of the electrical level indicator, as well as the fuses and relays for the motorized ball valves and the lighting, and the light switches for the interior and exterior lighting.

Accessories for each battery storage tank container include light masts, platforms with parapets and two DN100 pipe fittings with a length of 600m.

Use of battery storage for large consumers

Fuels and other consumables are delivered, stored, and used here. A tank truck receiving area is required next to the tank farm . The delivered medium is then dispensed towards the industrial plant.

We distinguish between single-media large tank farms and multi-media large tank farms . Single-media large tank farms are the previously described battery-type large tank farms, i.e., one medium in a battery.

Multi-media large tank farms consist of a storage tank container with simplified receiving and discharging technology installed on both ends of the tank body. This prevents the mixing of different media.

The operators of large tank farms are:

Large consumers such as power plants
Manufacturers such as specialty refineries and chemical manufacturers
Fuel and chemical suppliers
Logistics company for fuels and chemicals

Large battery tank farm for manufacturers of liquid media

Media such as fuels, additives and chemicals are delivered here, stored, refined in production, stored again and delivered to customers.

In addition to the tank farm, the tank truck receiving section and output section are required.

Fuel and chemical suppliers

The industrial supply companies have large central warehouses, but often also decentralized buffer or delivery warehouses. The difference here is the smaller storage volume per medium, but there are many media.

The central warehouse can store up to 1 million liters of a single medium. The buffer warehouse typically holds 50.000 or 100.000 liters of a single medium.

Special receiving and issuing sections with extensive equipment are installed for the central warehouse.

For the multi-media buffer storage system, receiving and dispensing equipment is installed in the machine compartment of each storage tank. This provides all the necessary technology for tank storage logistics in a very compact space.
