Abstract :

Landfills and also anaerobic digesters in waste treatment plants or waste water treatment plants, may produce biogas. As we know, this gas is formed by two main compounds which are CH4 and CO2, but there are also others like H2S, H2O, oxygen, siloxanes, etc. Biogas energetic valorization can be done in some different ways: obtaining electrical energy through cogeneration engines, also obtaining thermal energy in boilers or even getting biofuel when upgrading it. For these purposes, thorough cleaning will be always needed. This cleaning will be done by removing, depending on each case, some of those compounds that are present in biogas. Therefore, H2S removal will be performed by chemical scrubbing, biological treatment, biochemical way, or even adsorption. Siloxanes removal will be done using an activated carbon or regenerative thermal adsorption, and H2O will be removed by decreasing biogas temperature and condensing it. If in addition biogas producer wanted to obtain Biofuel, CO2 and other gases still remaining should be separated from CH4. This is called biogas upgrading and will be done by technologies like: water absorption, chemical absorption, membranes filtration, cryogenisation, etc. In my exposition, I�ll talk about all those technologies which will be very useful for biogas producers.
