Gas storage balloons

Gas buffers for storage of gases

Gas storage balloons, also known as gas holder balloons, gas bags or gas recovery membranes, are flexible, inflatable bladders used for industrial purposes. They often serve as an intermediate storage solution for the economical collection or storage of gases such as nitrogen, carbon dioxide, hydrogen, helium or other inert gases. These flexible containers (tanks) are used, for example, in breweries, technical universities and research institutes, and in special recycling processes.

Volumes from 0,5 m³ - 7500 m³
Spherical/cylindrical/
pillow shaped
or custom shapes
gas-tight

Custom shapes and sizes for all installation areas

For an optimal, cost-effective use of existing production areas, the balloons can be produced in various sizes and shapes, such as spherical, cylindrical, angular or cushion forms, depending on the spatial conditions. They range in volume from 0.5 m³ to 7,500 m³ (17 cubic feet to 265,000 cubic feet). Furthermore, custom shapes can also be manufactured according to individual requirements. All flexible tanks have the following advantages: they are lightweight in design and are easily inflated and deflated. This means that they can be quickly installed and removed. Depending on the customer’s requirements, they are equipped with inflation and deflation connections. Clamping or screw-on flanges made of stainless steel or flexible connections made of gas storage fabric are used.

Appropriate materials – special balloons for every type of gas

The storage balloons are manufactured from a very robust polyester fabric, which is coated with polyurethane on both sides. This fabric has a gas diffusion rate, measured with helium at 20 °C, of less than 1000 cm³ per m² in 24 h (70 cubic feet per 10 square feet per 24 h). To guarantee proper storage of diverse gases, each gas bag is designed to handle a specific type of gas. In addition to other special safety measures, the balloon fabric used for gas storage balloons for hydrogen is subjected to a special antistatic treatment. Balloons for the storage of helium have to be very gas-tight. CO2 storage balloons are made of a material approved for the food industry. The fabric for biogas storage balloons has to be extremely robust.

Secure anchoring on the ground using special tubular frames

In order to stand securely at the installation location, the balloons are suspended in a tubular frame. The tubular frames can optionally be suspended from the ceiling using steel cables or fixed to the floor with supports. Installation is very simple and can easily be performed by any technician. An integrated safety mechanism protects the balloon effectively against unintended overinflation. There are various methods available for measuring the fill level, such as wire-actuated encoders, ultrasonic and laser distance meters.

FAQ

Technical FAQ
What shapes and sizes of GAS STORAGE BALLOONS are available?

Spherical or cylindrical shapes are available as standard, in volumes from 0,5 – 7.500 m³ (1.64 – 24,600 cuft)
Special customer-specific designs can be manufactured in all sizes.

What types of gas can be stored?

Any gas which does not attack the surface of the GAS STORAGE BALLOON can be stored, e.g. helium, krypton, neon, xenon, argon, nitrogen, oxygen, hydrogen, carbon dioxide, etc.

Is the surface of the GAS STORAGE BALLOON food safe?

The material used in the manufacture of GAS STORAGE BALLOONS is suitable for the storage of gases that are used in the food industry.

Is the surface suitable for the storage of highly flammable gases?

It is possible to manufacture the fabric of the GAS STORAGE BALLOON with an electrostatically conductive surface so that even hydrogen can be stored

What is the leakage rate of the fabric used for the GAS STORAGE BALLOON?

Depending on the nature of the fabric, the leakage rate for helium is between 1l ( 0.04 cuft) and 1,5l (0.53 cuft) per m² (10.76 sqft) of surface area in 24 hours. The leakage rate for other gases can be up to 50 times higher.

How and where can the GAS STORAGE BALLOON be installed?

The GAS STORAGE BALLOON can be installed suspended in a tubular frame, anywhere in a building. It can occupy the entire volume of a room.

What kind of fittings are attached to the GAS STORAGE BALLOONS?

Many different types of fittings are used. The diameters are selected according to the particular requirements of the customer.

How many fittings can be installed on a GAS STORAGE BALLOON?

The GAS STORAGE BALLOON is normally provided with one fitting for inflation and one for deflation. In the case of condensation in the GAS STORAGE BALLOON, a separate condensate outlet device can be installed.

Where are the fittings on the GAS STORAGE BALLOON?

The fittings can be installed anywhere on the GAS STORAGE BALLOON, depending on the requirements imposed by any existing tubular frame at the customer’s site.

Operational FAQ
What techniques are available for checking the gas level?

The gas level can be checked by means of Bowden cables, ultrasound sensors and infrared sensors.
