Double Membrane Biogas Holder for a Beer Plant: Captures and Buffers the Biogas Produced from Brewing Waste Streams

Double Membrane Biogas Holder for a Beer Plant: Captures and Buffers the Biogas Produced from Brewing Waste Streams

A Beer Plant (or brewery) generates various brewing waste streams, including spent grain, surplus yeast, and high-strength effluent from cleaning and processing. These organic streams require effective management, with anaerobic digestion (AD) being the most sustainable solution. AD stabilizes the waste and produces a valuable energy co-product: methane-rich biogas. For the plant to maximize energy recovery, the biogas must be reliably captured and buffered to ensure a stable fuel supply to offset the significant energy demands associated with brewing processes.
The Double Membrane Biogas Holder is the optimal technology for this industrial application. It captures and buffers the biogas produced from brewing waste streams. Installed either as an integrated flexible roof on the digester or as a compact, free-standing unit , this holder provides a dynamic, hermetic reservoir. This system ensures every cubic meter of gas is captured, pressure fluctuations are safely managed, and a stable, continuous supply is maintained for boilers or CHP units, turning a waste product into a source of reliable, renewable energy for the plant.
 

Product Advantages for Brewing Waste Energy Recovery

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the substantial gas output and operational stability requirements typical of continuous brewing processes.

Integrated Gas Capture and Supply Stability

The system acts as the integrated flexible roof of the digester tank, ensuring maximum gas capture efficiency by collecting the gas instantly. The inner membrane's volume dynamically expands and contracts to accommodate the natural volume fluctuations in biogas production. This dynamic buffering is essential for regulating the low pressure of the gas, preventing system instability, and ensuring a smooth, constant flow to the plant’s utilization equipment. This stability is critical for protecting sensitive downstream machinery and maximizing energy uptime.

Fugitive Emission and Odor Control

Beyond energy recovery, the system provides a crucial hermetic seal over the digester. This is paramount for fugitive emission control (preventing the release of methane, a potent greenhouse gas) and for significantly reducing odor emissions associated with high-strength brewing wastes. The gas-tight integrity ensures compliance with strict environmental regulations and improves the facility's overall environmental performance.

Support for Aluminum Dome Roofs

Where maximum corrosion resistance and structural longevity are prioritized for the digester tanks—a critical requirement in the often humid and corrosive brewery environment—the Double Membrane Holder can be integrated with a tank protected by an Aluminum Dome Roof . While the membrane system provides the essential flexible gas-tight envelope, the aluminum dome offers superior long-term corrosion protection and structural support for the entire digester tank structure, enhancing overall system durability.
