What is Double Membrane Gas Holder?


Double Membrane Gas Holder/Gas storage Cabinet is a durable air supported structure specifically designed for the purpose of biogas storage.


It can be used as an independent gas storage structure, or be installed as part of the anaerobic digestion system in a wastewater treatment plant, agricultural digestion schemes, landfill sites and combined heat-and-power plants that use digested organic materials to generate biogas as an energy source.


Scope of application:

It apples to a variety of neutral gases such as methane, air, carbon dioxide, oxygen and so on.


Double Membrane Gas Holder Features:

• Capacity 50 – 10000m3
• Quick to Install
• Long service life
• Unique membrane fabrics

• Control systems for plant integration
• To Meet customer requirements

• Low capital cost in comparison to steel gas storage tanks 


Fundamental consist of this system


1.      Main material: Biogas special-used membrane material is made of highly tear-resistant and anti-corrosion polyester fabrics.

2.      Gas in and out system: standard pipeline

3.      Gas booster fan 

4.      Observation window 

5.      Auto-control system

6.      Alarming system

7.      Display system 

8.      Safety protector: safe by water seal and electric decompression

9.      System lifespan is 25 years 


Membrane Material:


Auto Control System with digital data output:




Working principle:


All the membranes together form two spaces.The inner membrane serves as storage space of various gases.

The intermediary space between outer membrane and inner membrane is for pressure regulating.

A permanently functioning air blower feeds air into the intermediary space according to inner membrane pressure which shows through the signal on auto-control panel.
