500m³ Dual membrane biogas bag for biogas plant

Product Description

The MDS gasholder can be installed on the ground, typically configured as a ¾ sphere, or mounted on top of an anaerobic digester or tank, serving both as a robust cover and storage vessel. The 500m³ Dual membrane biogas bag for biogas plant comprises an outer and inner membrane; the outer membrane acts as a protective layer that is consistently maintained under pressure to withstand wind and snow loads, regardless of extreme climatic conditions. The inner membrane expands and contracts beneath the outer layer in response to variations in gas generation and consumption. When the dual membrane gas balloon is ground-mounted on a concrete foundation, it features an additional bottom membrane that seals the gas storage area to the foundation.

Each gasholder is designed in compliance with stringent European and U.S. standards concerning materials of construction, structural integrity, storage capacity, snow load resistance, wind load tolerance, operating pressure specifications, and fire resistance criteria. Furthermore, all 500m³ Dual membrane biogas bag for biogas plant are custom-designed and manufactured according to specific project requirements regarding size, configuration (e.g., dome-shaped, rectangular, square, donut-shaped), and strength using high-quality PVC-coated polyester fabrics. Product design principles prioritize system safety while ensuring reliability and ease of control.

The engineering behind each 500m³ Dual membrane biogas bag for biogas plant design is tailored to meet individual project needs while incorporating MONDES’s extensive expertise regarding external forces acting upon these structures as well as appropriate material selection for longevity. This commitment is evidenced by over 1,800 successfully operating membrane gasholders worldwide—a benchmark unmatched by any other manufacturer in this field.

We offer innovative solutions that are cost-effective yet durable for addressing your unique challenges.

Main Technical Parameters

Material Features

The biogas storage tank membranes are highly tear resistant polyester fabrics with a special PVC surface treatment and acrylate varnish. The fabric is also resistant to the impact of the different biogas ingredients and the white colour of its external membrane has a highly reflective effect. The construction and dimensions of the double membrane biogas storage tank comply with all relevant standards.

• Biogas storage system fabric is highly flame-poof according to DIN 4102-B1
• Higher specification fabric is available on request
• The special surface treatment formula guarantees high resistance against permeability & UV
• All biogas storage tanks are resistant to wind and heavy snow and guarantee safe operation
• The temperature resistance ranges from –30°C to +70°C

Advantage

Compared with Chinese traditional biogas storage (wet-type, dry-type), membrane storage system has the advantage as follows:

• Biogas can be 100% used: the inner biogas can be totally squeezed out which is hardly to achieve by the traditional one.
• In light weight: It weighs only a small percentage than the traditional one. This does great good for make, transportation, installation, etc., and saving a lot of construction time and material cost.
• No need to maintain for long time: For the membrane is made of the super anti-corrosion material and can last more than 15 years in the biogas circumstance. Meanwhile, it is well welded by high frequency, so we do not have to do regular maintain when use membrane storage.
• It saves much time and labor: For it is small and light, also the membrane has been well-shaped in factory, so the on-site installation will just cost only a few days.
• Saving money: From the mentioned above, we can know that the total cost is lower than that of the traditional one.
• Anti-freezing: For there is no water in the inner structure, there is no need to worry about the frozen problem in the cold area.
• Keep warm: As we know, air is the perfect medium to keep warm. So the air between two-layer membranes makes the system warmer than the traditional one.
• Artistic: The main color of the membrane is grey white, so it can easily be matched. Meanwhile, the whole structure is designed to be spheroidal, and this arise the sense of beauty.
• Comparatively safe when accident happens: Anyway, biogas is flammable gases, if by any chance explosion happens, it will not produce so much injury pieces as other hard material made storage.
• Easily repair: If unforeseeable things happened, most of the maintenance can be easily done at present. For example, when gas leaking, it only need a small patch.
• Easily remove: If customer needs to remove the system, it can be easily achieved. There is no need to worry about the by-way produced useless and difficult transportation. From this point, it is better than any kind of traditional design.
• Fire protection: The material of membrane field is non-flammable, the fire protection grade reaches the Euro-standard B.
