Biogas Holder for a Compressed Biogas Plant Project: Provides the Buffer Capacity Required to Stabilize the Gas Stream Before Purification and Compression (Upgrading to Bio-CNG)

Biogas Holder for a Compressed Biogas Plant Project: Provides the Buffer Capacity Required to Stabilize the Gas Stream Before Purification and Compression (Upgrading to Bio-CNG)

A Compressed Biogas Plant Project involves upgrading raw biogas into high-quality biomethane (or Bio-CNG) suitable for vehicle fuel or injection into the natural gas grid. This complex upgrading process, involving purification and high-pressure compression, requires an extremely stable and consistent inlet gas flow. The system requires a dedicated storage solution that provides the buffer capacity required to stabilize the gas stream before purification and compression (upgrading to Bio-CNG). Without this crucial buffer, the purification and compression equipment would suffer constant pressure and flow swings, leading to inefficient operation and equipment damage.

The Biogas Holder, utilizing the Double Membrane design, is the optimal technology for this specialized Bio-CNG upgrading application. It efficiently provides the buffer capacity required to stabilize the gas stream before purification and compression (upgrading to Bio-CNG). Installed as a dedicated storage sphere , this holder acts as the essential intermediary between the variable production phase and the high-demand utilization phase. By absorbing all production fluctuations, it guarantees the stable, consistent gas inlet conditions necessary for high-efficiency purification and compression equipment.

Product Advantages for Bio-CNG Upgrading Stability

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to optimize the performance and protect the sensitive equipment used in compressed biogas and upgrading projects.

Stabilization for Upgrading Equipment

Gas purification and compression units operate optimally at precise, steady flow rates and pressures. The inner membrane of the holder provides the dynamic buffer capacity essential for absorbing the hourly and daily fluctuations in raw biogas production. This dedicated buffer ensures a stable and continuous gas stream is fed to the purification units (e.g., membranes or scrubbers) and the subsequent compressors, maximizing their efficiency and minimizing wear and tear.

Optimal Pressure Regulation

While the buffer handles volume stability, the outer membrane's control system ensures a precise pressure output. This active regulation guarantees a stable discharge pressure that meets the specific inlet requirements of the gas upgrading train. Maintaining this pressure consistency is non-negotiable for maximizing biomethane purity and achieving high compression rates required for Bio-CNG.

Support for Aluminum Dome Roofs

In the heavy-duty industrial environment of Compressed Biogas Plant Projects, long-term durability and structural integrity are essential. The Biogas Holder can be integrated with a tank protected by an Aluminum Dome Roof. While the membrane system provides the essential gas-tight, flexible containment, the aluminum dome offers superior long-term corrosion protection and robust structural support for the digester tank, ensuring the resilience of the entire feed system infrastructure.
