Double Membrane Biogas Holder for a Biogas CNG Plant: Offers Crucial Low-Pressure Buffer Storage for Gas En Route to Compression

Double Membrane Biogas Holder for a Biogas CNG Plant: Offers Crucial Low-Pressure Buffer Storage for Gas En Route to Compression

A Biogas CNG Plant is a facility designed to upgrade and compress raw biogas into high-quality, high-pressure compressed natural gas (CNG) suitable for vehicle fuel or grid injection. In this process, the efficient handling of the low-pressure biogas produced by the digesters is paramount. The raw gas flow is inherently variable, but the high-value equipment—specifically the upgrading units (purification) and the compression system—requires a crucial low-pressure buffer storage solution to ensure a stable, continuous feed. This buffer is essential for maximizing the lifespan of the compressors and ensuring consistent product quality.

The Double Membrane Biogas Holder is the indispensable component that fulfills this critical function. It offers crucial low-pressure buffer storage for gas en route to compression. Installed as an external, free-standing unit or integrated with the digester, this flexible holder dynamically manages the substantial, fluctuating gas volume. By providing a stable pressure and flow rate to the downstream equipment, the system optimizes the efficiency of the upgrading process, protects the high-pressure compressors from damaging surges and drops, and ultimately ensures the continuous, cost-effective production of Bio-CNG.

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 within the infrastructure of a Biogas CNG Plant, offering superior containment, pressure regulation, and long-term durability.

Product Advantages for Pre-Compression Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to support the rigorous demands of a Biogas CNG facility, maximizing efficiency and minimizing wear and tear on high-value equipment.

Crucial Buffer and Flow Stabilization

The primary advantage for a Biogas CNG plant is the holder's ability to act as the crucial buffer storage unit. Raw biogas production is inherently variable, but the upgrading and compression units require a stable, continuous flow and regulated low-pressure supply. The holder's dynamic, flexible volume absorbs production peaks and troughs, ensuring the gas-upgrading equipment operates at its optimal, steady-state design point. This directly translates to guaranteed performance and reliability, stabilizing the gas en route to compression.

Protection of High-Value Compressors

The compression stage is the most energy-intensive and equipment-sensitive part of the process. An unstable feed flow or pressure can cause severe wear, stress, and operational failures in the compressors. The double membrane holder acts as a protective barrier, ensuring that only a regulated, steady stream of purified, low-pressure gas reaches the compressor intakes. This function significantly extends the lifespan of the high-value compression equipment and reduces maintenance costs and unplanned downtime.

Cost-Effective, Flexible, and High-Volume Storage

The modular, lightweight nature of the double membrane holder makes it a highly cost-effective solution for providing the required large volume of low-pressure storage capacity compared to building rigid, external gas holders. This ensures simplified, rapid installation and significantly reduces the civil engineering requirements. The inherent flexibility allows the plant to continue digestion during temporary maintenance of the upgrading/compression stages, minimizing costly flaring.
