Double Membrane Biogas Holder for Biogas Fermentation Tanks: Ensures Gas-Tight Capture and Storage of the Valuable Fuel Product

Double Membrane Biogas Holder for Biogas Fermentation Tanks: Ensures Gas-Tight Capture and Storage of the Valuable Fuel Product

The process of anaerobic digestion (AD) hinges on the effective conversion of organic feedstock inside the Biogas Fermentation Tank into a stabilized product and a valuable gaseous fuel. This fuel, biogas, is produced at a low, variable pressure. For the AD facility to operate at peak efficiency and meet environmental standards, it must have a solution that ensures gas-tight capture and storage of this valuable fuel product. Leaks lead to economic losses and environmental concerns, while unstable storage undermines the entire energy recovery system.

The Double Membrane Biogas Holder is the essential, integrated technology that guarantees this level of performance. It is installed directly onto the fermentation tank to ensure gas-tight capture and storage of the valuable fuel product. By serving as the flexible dome, the holder provides a hermetic seal against the atmosphere and acts as a dynamic reservoir. This system ensures every cubic meter of gas is contained, the tank pressure is safely regulated, and a stable gas supply is maintained for downstream utilization, which is crucial for maximizing the value of the fermentation process.

Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in advanced containment solutions, specializes in engineering high-performance storage systems. Our Double Membrane Biogas Holders are state-of-the-art gas holders designed to integrate seamlessly with various fermentation tanks, offering superior gas containment, pressure regulation, and long-term durability.

Product Advantages for Gas-Tight Integrity

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to maximize the efficiency, safety, and gas recovery of biogas fermentation tanks. The flexible dome design provides distinct advantages for maintaining system integrity.

Guaranteed Gas-Tight Capture

The primary function of the double membrane holder is to act as a hermetic seal for the fermentation tank. This gas-tight capture is achieved by mounting the system directly to the tank flange, preventing the escape of valuable biogas and odors. This integrity is vital for maximizing the energy yield and ensuring compliance with stringent environmental regulations regarding methane emissions. The structure effectively contains the low-pressure gas, protecting the entire process from atmospheric interference.

Flexible, Low-Pressure Regulation

Gas production from the fermentation process is rarely constant, fluctuating with temperature and feedstock activity. The balloon's design provides a flexible, low-pressure reservoir that can dynamically expand and contract to accommodate these volume and pressure fluctuations. This acts as a perfect buffer, regulating internal pressure to prevent stress on the tank structure and ensuring a smooth, stable flow of gas to downstream utilization or scrubbing equipment.

Superior Durability and Resilience

The robust, double-membrane architecture ensures exceptional structural resilience. The outer membrane is air-supported to form a rigid, protective dome that shields the inner gas-holding membrane from external environmental stresses, including high winds, heavy precipitation, and ultraviolet (UV) radiation. This proven durability, combined with the material’s resistance to corrosive elements in raw biogas, guarantees a long operational lifespan and low maintenance requirements.
