What is a Double Membrane Biogas Storage Tank?

A Double Membrane Biogas Storage Tank is a specialized storage system designed to store the biogas produced during the anaerobic digestion of organic materials. These tanks feature a double membrane roof system, which ensures the safe containment of biogas while providing flexibility for pressure control and gas storage volume adjustment. The outer membrane acts as a cover, while the inner membrane is inflated with the biogas, creating a pressurized storage environment.

The double membrane design offers several advantages, including improved gas storage efficiency, enhanced safety, and the ability to control the pressure inside the tank to optimize biogas storage.

Key Benefits of Double Membrane Biogas Storage Tanks

1. Safe and Secure Biogas Storage

The primary function of the Double Membrane Biogas Storage Tank is to securely store the biogas produced during anaerobic digestion. Biogas, which is primarily composed of methane, is highly flammable and requires a safe, controlled environment for storage. The double membrane system provides a gas-tight seal, preventing leakage and ensuring that the biogas is securely contained within the tank.

The inner membrane is designed to inflate and hold the biogas, while the outer membrane acts as a secondary layer of protection, further ensuring that the stored biogas remains safely contained. This system minimizes the risk of accidents and enhances the overall safety of the anaerobic digestion plant.

2. Flexible Pressure Control

One of the unique advantages of the Double Membrane Biogas Storage Tank is its ability to manage and maintain internal pressure. As the anaerobic digestion process progresses, the biogas volume and pressure inside the tank will fluctuate. The double membrane design allows the pressure to be adjusted by inflating or deflating the inner membrane as needed.

This pressure control feature ensures that the tank can handle changes in gas production, providing consistent storage capacity and preventing over-pressurization, which could damage the tank or pose safety risks. The ability to adjust the pressure also makes it easier to regulate biogas extraction for use in energy generation or other applications.

3. High Durability and Long-Term Performance

Our Double Membrane Biogas Storage Tanks are made from high-quality materials, including corrosion-resistant steel and durable membrane materials, ensuring a long service life even in the harshest conditions. The Glass-Fused-to-Steel (GFS) coating used in the tank panels provides excellent protection against corrosion, making the tank ideal for biogas storage in anaerobic environments.

The double membrane system is engineered to withstand the pressure exerted by the stored biogas and provide a reliable storage solution for years to come. This durability reduces maintenance requirements, ensuring that the tank remains operational with minimal upkeep.

4. Efficient Gas Extraction and Utilization

The double membrane design also improves the efficiency of biogas extraction. As biogas is produced, the inner membrane inflates, and the stored gas can be extracted for use in power generation, heating, or other applications. The pressure control system ensures that biogas can be extracted at a consistent flow rate, making it easier to harness energy from the stored biogas efficiently.

Biogas production is often used for renewable energy generation, such as powering engines, turbines, or fuel cells. The Double Membrane Biogas Storage Tank ensures that the biogas is available for energy conversion with minimal fluctuations in pressure or volume, providing a stable energy source for anaerobic digestion plants.

5. Customizable Capacity and Design

At Center Enamel, we understand that every anaerobic digestion project is unique. That’s why we offer customized capacity options for our Double Membrane Biogas Storage Tanks. Whether your project requires a small-scale solution or a large-scale biogas storage system, we can design and manufacture a tank that meets your specific needs.

Our tanks come in various sizes and configurations, allowing for flexibility in design and installation. Whether you are building a biogas plant for agricultural waste, municipal sewage treatment, or industrial effluent processing, we can provide a tailored solution that fits your project requirements.

6. Easy Installation and Low Maintenance

The modular design of our Double Membrane Biogas Storage Tanks makes installation straightforward and efficient. The panels are pre-fabricated in our factory, which allows for quick on-site assembly. This reduces installation time and costs, enabling your anaerobic digestion project to be up and running in no time.

Once installed, the tank requires minimal maintenance. The Glass-Fused-to-Steel (GFS) coating protects the tank from corrosion, reducing the need for frequent repairs and maintenance. The double membrane system is also low-maintenance, as the inner membrane is designed to be durable and resistant to damage.
