Double Membrane Roofs for Compressed Biogas Plants: Holds biogas before

Product Specification

Double Membrane Roofs for Compressed Biogas Plants: Holds biogas before purification and compression.

The evolution of biogas as a renewable energy source has led to the development of compressed biogas (CBG) plants, which convert raw biogas into a high-purity fuel that is functionally equivalent to natural gas. This process involves several critical steps, including purification and compression, which require a reliable buffer system to hold the biogas before it undergoes these transformations. In a CBG plant, the initial storage of raw biogas is a crucial first step, as any leakage or contamination can compromise the entire upgrading process. To address this need, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in containment solutions, has engineered Double Membrane Roofs for Compressed Biogas Plants. These innovative roofs are specifically designed to hold biogas before purification and compression, providing a safe, sealed, and efficient buffer that ensures a continuous and high-quality supply of gas for the upgrading process.

Product Advantages

Center Enamel's Double Membrane Roofs are a sophisticated, three-layer system designed for high-performance gas containment. The structure includes an outer membrane, an inner membrane, and a bottom membrane, all supported by a series of precision control and safety components. This innovative design provides a number of key advantages that directly address the core needs of CBG plants. The multi-layered structure and advanced sealing techniques ensure exceptional airtightness, which is paramount for preventing the escape of valuable biogas and protecting it from atmospheric contamination. The outer membrane is continuously inflated to create a stable, protective dome, while the inner membrane dynamically adjusts to the volume of gas, allowing for efficient collection and storage. This system effectively maximizes the energy value of the stored gas and significantly reduces greenhouse gas emissions. For long-term peace of mind, the roofs are constructed from a blend of materials with superior anti-corrosion and UV resistance. This durability ensures the system maintains its structural integrity and performance over an extended period, requiring minimal maintenance and offering a cost-effective solution in a variety of climates.

Safety is engineered into the very core of our design. The roofs are equipped with multiple safety features, including sensitive over- and under-pressure relief systems that automatically adjust to pressure fluctuations. This prevents the tanks from being damaged by internal pressure changes, providing a secure and stable containment system even under challenging operational conditions. This enhanced safety and reliability ensures continuous operation and protects the integrity of the entire biogas system.

Product Application Areas

Center Enamel's Double Membrane Roofs are a key component in a wide range of industries that require a reliable biogas storage solution before purification and compression. In biogas engineering, the roofs are a core component of anaerobic digestion plants, effectively sealing the digester tank and storing biogas produced from various waste streams. This is particularly relevant for CBG plants, where the biogas must be held securely before it is fed into an upgrading unit. The roofs are also widely used in both industrial and municipal wastewater treatment plants to collect and hold biogas generated during the treatment of effluents. This not only helps manage waste products but also turns them into a valuable energy source that can be upgraded and used to power the treatment plant itself, contributing to a more circular economy and reducing operational costs. Additionally, they are integral to facilities for livestock and food waste treatment. By providing a secure sealed cover and containment for the biogas produced during digestion, these roofs help large-scale farms and urban waste management facilities handle their waste responsibly, while simultaneously generating a reliable renewable energy source that can be upgraded to biomethane.
