Dual Membrane Gas Domes for Methane Storage

System description of dual membrane gas domes for methane storage
The outer membrane forms the actual protective construction and is always under a for the statics necessary positive pressure. Through a built-in viewing window the operations inside can be observed at any time. The actually usable holder forms the inner membrane. This membrane moves up or downwards depending on the filling level. In the gas holder with base plate a bottom membrane seals the storage space to the concrete foundation. With the help of the anchoring ring, the membranes are attached to the foundation. Particular emphasis is on the dimensioning of the membranes. Each holder will be calculated individually in consideration of the loads (internal pressure, wind and snow loads). As a result, membranes with high tensile strength are selected. The PVC-coated membranes are flame retardant according to DIN 4102 B1, fungicide, and equipped with an increased UV protection. To protect the membranes from the substances in the biogas (CH4, CO2, H2S, etc.) the inner- and bottom membranes have a special coating.
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.
The level measurement enables an optimal utilization of the storage volume and control of the slave units (e.g. flare, engine, burner, etc.) "
