Biogas

biogas

The raw biogas comes from the decomposition of natural organic materials and it is generally consisting of a mixture of methane (50-65% ), carbon dioxide and other such called “contaminants”, such as syloxanes, hydrogen sulphide and water.

Recent studies have shown that methane itself when released into the atmosphere has got a negative impact on the planet greenhouse effect. In fact the biogas impact in accelerating the planet climate changes is estimated to be 21 times greater than carbon dioxide. For this reason, any methane releases into the atmosphere must take place after the methane had been oxidized, whist recovering as much energy as possible all over the oxidizing process.

At the present, the most common way of achieving methane oxidation is currently through biogas feed of modified natural gas engines for cogeneration purposes. Besides, a couple more convenient alternatives to the heat&power generation are available, in particular: the bio-methane injection into any private or public gas networks, or the use of it as a vehicle fuel. Both those options do require the raw biogas to be thoroughly cleaned through an appropriate purification process, in order for any contaminants to be removed in accordance with the final product purpose specification (biomethane).

 

Thanks to its technological know-how gained in the gas treatment and compression fields since 1975, SAFE has celebrated the new born biogas division opening in 2009, with the first biogas upgrading pilot plant delivered and put in operation at San Giovanni in Persiceto (Italy). Since then, SAFE has been keeping optimizing and innovating its compression-core products, for providing all Customers with the most reliable and best performing technology.
