Gas Storage and Covering Membranes

Biogenic provides gas storage and covering membranes for biogas plants, treatment plants, and agriculture.

The membranes are of the highest quality, and the solutions with an insulating third layer in the gas storages are a truly unique and energy-saving solution.

A tight, high-quality gas storage is definitely an advantage for both the climate and the economy in biogas plants.

Therefore, we also offer to carry out regular leakage inspections to monitor and document the tightness.

Different Solutions and Implementations

Simple Conical Covering for Tanks

The M1 cone is designed for standard covering of slurry tanks, pre-storage tanks, and final storage tanks.

Installation is quick and covers tanks with a typical radius of 10 to 40 meters.

2-Layer Gas Storage for Tank

The M2 dome is a pressurized storage membrane for installation on concrete or steel tanks.

The blower adds air between the membranes, maintaining a constant pressure on the gas in the tank.

Built from seam-welded PVC fabric that is resistant to UV, H2S, and has high strength.

The membranes can be customized in many ways, for higher pressure, with balconies for submerged mixers, with logos and colors, etc.

3-Layer Gas Storage for Tank

The M3 dome is a pressurized storage membrane for installation on concrete or steel tanks with an extra 3rd layer.

The third layer is an extra layer of PVC membrane that creates an additional barrier between the gas in the inner membrane and the air in the outer membrane.

An opening into the layer below the middle membrane allows for the detection of even the smallest gas leaks.

The blower adds air between the membranes, maintaining a constant pressure on the gas in the tank.

Built from seam-welded PVC fabric that is resistant to UV, H2S, and has high strength.

The membranes can be customized in many ways, for higher pressure, with balconies for submerged mixers, with logos and colors, etc.

3-Layer Gas Storage for Tank with Heat Insulation

The M3 Heat-Shield dome is a pressurized storage membrane for installation on concrete or steel tanks with an extra heat-insulating 3rd layer. 

The 3rd membrane layer is not just an extra layer of PVC membrane but a robust and insulating membrane, similar in appearance to bubble wrap, but much stronger.

It significantly reduces heat loss through the cover, making it an excellent solution for protecting against heat loss in the cold Nordic climate.

The blower adds air between the membranes, maintaining a constant pressure on the gas in the tank.

Built from seam-welded PVC fabric that is resistant to UV, H2S, and has high strength.

The membranes can be customized in many ways, for higher pressure, with balconies for submerged mixers, with logos and colors, etc.

2-Layer Gas Storage for Installation on a Foundation

The M2 gas storage is a pressurized storage membrane for installation on a foundation.

The gas storage is often performed as a half-sphere or three-quarters sphere. A half-sphere design is recommended in areas with high wind loads.

The blower adds air between the membranes, maintaining a constant pressure on the gas in the tank.

Built from seam-welded PVC fabric that is resistant to UV, H2S, and has high strength.

The membranes can be customized in many ways, for higher pressure, with logos and colors, etc.

2-Layer Gas Storage for Installation on a Frame

The M2 gas storage is a pressurized storage membrane for installation on a frame or steel structure.

The gas storage can be executed in a range of different designs.

The blower adds air between the membranes, maintaining a constant pressure on the gas in the tank.

Built from seam-welded PVC fabric that is resistant to UV, H2S, and has high strength.

Container Gas Storage

The container gas storage is a storage membrane installed in a container.

The gas storage can be executed in a range of different designs.

The blower is mounted on the container wall and supplies air around the membrane, maintaining a constant pressure on the gas.

Built from seam-welded PVC fabric that is resistant to UV, H2S, and has high strength.
