VSO BIOGAS TECHNOLOGIES specialist in gas holders for the storage and regulations biogas

Since the 1990s, VSO, a subsidiary of the BHD group, has devoted its expertise and know-how to the protection of the environment by developing biogas storage and regulation solutions. Currently, VSO designs, manufactures and installs double membrane gas holders throughout the world.

Biogas is a gas, which is produced by the breakdown of all organic materials in the absence of oxygen, known as anaerobic digestion. The benefits of anaerobic digestion are now widely accepted: energy production in the form of biogas and electricity, contribution to reducing greenhouse gas emissions, etc. VSO BIOGAS TECHNOLOGIES is involved in the biogas production chain, at the anaerobic digestion stage.

The VSO BIOGAS TECHNOLOGIES gas holders

The VSO BIOGAS TECHNOLOGIES gas holder is a flexible double membrane tank used to store the biogas coming from the digester tank. Depending on the quantity of waste treated, the quantity of biogas will not be the same and therefore the VSO BIOGAS TECHNOLOGIES biogas storage tank must be designed to make continuous adjustments in order to cope with this problem.

The internal membrane of the gas holder inflates and deflates according to the volume of biogas. Should the pressure be too high, the excess is destroyed using a gas holder accessory called a flare. The VSO BIOGAS TECHNOLOGIES gas holder is fitted with all the peripherals needed for the gas holder to work properly, from the regulation of the biogas volume being stored to the destruction of the excess gas.
