2 Membrane Gasholder

2Master

Two membrane constant-pressure gasholders are designed to store biogas made from anaerobic digestion of organic waste and sludge.

They are manufactured with biogas resistant polyester reinforced PVC membranes seam welded by high frequency electronic machines.

The 2MASTER system is made with a single upper membrane, pressurized by an air fan 24 hours a day to give a pneumatic push on the inner biogas chamber, keeping the biogas chamber at a prefixed and constant positive pressure. The one-piece gas chamber can be made in the factory or on site. Closed piece construction prevents gas losses through the anchor bolts that fix the cover to the ground or tank

Main characteristics

High storage and gas flow rate

The 2MASTER system is suggested for use in all cases where storage volume is greater >than 3000 m³. The lighter weight of the 2 membrane allows larger gas holders to be constructed. The 2 membrane system is also proposed where high and variable gas flow rates are expected.

Shape variability

It is possible to manufacture gasholders with either a ½ sphere or ¾ sphere shape. The 2 membrane system is also proposed where high and variable gas flow rates are expected. Big sizes and sites where high winds are expected then a ½ sphere gas holder would be recommended.

Low cost

Two membrane construction and a simple air pressurization system used in the 2MASTER system allow for a low and competitive cost.
