500m³ Dual Membrane Gas Domes for Methane Storage
Product Description
The concept of "500m³ Dual Membrane Gas Domes for Methane Storage" refers to a specialized storage solution designed to safely and efficiently contain methane gas, which is a significant component of biogas. These domes are constructed using two layers of membrane materials that provide enhanced structural integrity and safety features compared to traditional single-layer storage systems.
The outer membrane serves as the primary barrier against environmental factors such as weather conditions, while the inner membrane acts as an additional safeguard, ensuring that any potential leaks or breaches in the outer layer do not compromise the overall containment system. This dual-layer design minimizes the risk of methane escaping into the atmosphere, thereby addressing concerns related to greenhouse gas emissions.
To ensure an optimum gas mixture, each gas supply and gas conduction is provided separately. A safety valve against excess pressure is supplied as standard.
The supporting air blower provides the necessary pressure of the gas reservoir to absorb the external forces such as wind and snow load and create the form on the gas system. A separate air tube connects the blower to the reservoir. The check valve prevents air leakage in case of failure of the blower. For safety in the air system a pressure control valve is installed. This valve controls the operating pressure and agrees to a minimum required pressure (static stability, failure of the blower) independently in the outer membrane. This device is stable with existing gas production capacity of storage.
he level measurement enables an optimal utilization of the storage volume and control of the slave units (e.g. flare, engine, burner, etc.) "
In addition to their functional benefits, 500m³ Dual Membrane Gas Domes for Methane Storage can be tailored in size and capacity according to specific storage needs. They are suitable for various applications including industrial use, energy production facilities, and even agricultural settings where biogas is generated from organic waste.
