Biomethane: natural and renewable
What is Biomethane?
Biomethane is a natural and renewable gas, derived from the purification process (upgrading) of the biogas obtained from the enhancement of products and by-products of the agricultural and agro-industrial chain, from Organic Waste and the treatment of water and waste sludge.
The benefits of Biomethane
There are two ways to use biomethane: the injection of natural gas into the existing network and use as a fuel for vehicles.
Thanks to its characteristics and methods of use, the biomethane contributes to:
promoting local and circular economies
increasing sustainable mobility for the transport sector
supporting the environment by reducing emissions
achieving the country's energy independence through the use of renewable energy sources
We transform biogas into biomethane
Biogas purification with BTS Biogas technology
Washing process using pressurized water
With this process, CO₂ and hydrogen sulphide are dissolved in water and separated from biogas.
The biogas is subjected to pressure and purified inside a column filled with countercurrent water. The "unwanted" gases are absorbed by the water while the purified gas, after passing through the column, is drained, dried and made available for entry into the network or for direct use.
At various points in the system, heat is extracted which can be used for heating the tanks of biogas plants.
