1. Arriv\u00e9e du Biogaz<\/div>
Le biogaz brut achemin\u00e9 vers l\u2019unit\u00e9 WAGABOX\u00ae contient du m\u00e9thane, du dioxyde de carbone et de l\u2019air (oxyg\u00e8ne et azote), ainsi qu\u2019une forte teneur en humidit\u00e9. Il contient \u00e9galement des traces d\u2019autres gaz, notamment du sulfure d\u2019hydrog\u00e8ne et des compos\u00e9s organiques volatils (COV). Ce biogaz brut doit \u00eatre pr\u00e9trait\u00e9 avant de commencer la s\u00e9paration du m\u00e9thane.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
2<\/div><\/div><\/div>
2. Pr\u00e9traitement<\/div>
Avant la valorisation du biogaz, le sulfure d\u2019hydrog\u00e8ne est \u00e9limin\u00e9 \u00e0 l\u2019aide de charbon actif afin de pr\u00e9venir la corrosion, de limiter les \u00e9missions de SOx et de prot\u00e9ger les \u00e9quipements. Le biogaz est ensuite refroidi dans un \u00e9changeur thermique pour \u00e9liminer l\u2019eau par condensation.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
3<\/div><\/div><\/div>
3. Compresseur Membrane<\/div>
Le module de valorisation par membranes se compose d\u2019un compresseur et de plusieurs ensembles de membranes, tous install\u00e9s \u00e0 l\u2019int\u00e9rieur d\u2019un conteneur. L\u2019unit\u00e9 s\u00e9pare le dioxyde de carbone des autres composants du biogaz. Le conteneur abrite \u00e9galement d\u2019autres \u00e9quipements : les automates de pilotage de l\u2019installation, les vannes de r\u00e9gulation ainsi qu\u2019un autre compresseur qui achemine le biom\u00e9thane vers le poste d\u2019injection.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
4<\/div><\/div><\/div>
4. Elimination des COVs<\/div>
Le syst\u00e8me d\u2019adsorption modul\u00e9e en pression, ou PSA (*Pressure Swing Adsorption*), \u00e9limine les compos\u00e9s organiques volatils pr\u00e9sents dans le biogaz. Il se compose de trois cuves install\u00e9es c\u00f4te \u00e0 c\u00f4te, contenant diff\u00e9rents lits adsorbants.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
5<\/div><\/div><\/div>
5. Filtration Membranaire<\/div>
La pression est augment\u00e9e, puis le gaz est refroidi, s\u00e9ch\u00e9 et d\u00e9barrass\u00e9 de l\u2019huile. Le CO\u2082 est ensuite \u00e9limin\u00e9 gr\u00e2ce \u00e0 deux \u00e9tapes de membranes polym\u00e9riques.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
6<\/div><\/div><\/div>
6. PTSA<\/div>
Le syst\u00e8me d\u2019adsorption modul\u00e9e en pression et en temp\u00e9rature, ou PTSA (Pressure and Temperature Swing Adsorption), \u00e9limine les traces r\u00e9siduelles de dioxyde de carbone pr\u00e9sentes dans le biogaz avant la distillation cryog\u00e9nique, afin d\u2019\u00e9viter la formation de \u00ab glace carbonique \u00bb.\nLe PTSA se compose de deux cuves contenant des adsorbants microporeux et fonctionnant en alternance : tandis qu\u2019une cuve est en phase d\u2019adsorption, l\u2019autre est en phase de r\u00e9g\u00e9n\u00e9ration.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
7<\/div><\/div><\/div>
7. Distillation Cryog\u00e9nique<\/div>
L\u2019unit\u00e9 de distillation cryog\u00e9nique s\u00e9pare le m\u00e9thane de l\u2019azote et de l\u2019oxyg\u00e8ne contenus dans le biogaz. Elle se compose d\u2019une colonne de distillation et d\u2019un \u00e9changeur thermique. Une faible quantit\u00e9 d\u2019azote liquide est utilis\u00e9e, notamment lors de la phase de d\u00e9marrage.\n\nLe biogaz est refroidi \u00e0 -161 \u00b0C (112 K) afin de liqu\u00e9fier le m\u00e9thane, qui est ensuite r\u00e9cup\u00e9r\u00e9 par gravit\u00e9, tandis que les gaz de l\u2019air sont dirig\u00e9s vers l\u2019oxydeur.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
8<\/div><\/div><\/div>
8. Poste d'injection<\/div>
\u00c0 l\u2019issue du processus de valorisation, le m\u00e9thane atteint une puret\u00e9 de 98 % : le gaz issu des sites de stockage est alors transform\u00e9 en biom\u00e9thane.\nLe biom\u00e9thane est ensuite achemin\u00e9 vers le poste d\u2019injection du gestionnaire de r\u00e9seau. Ce poste comprend les \u00e9quipements n\u00e9cessaires pour v\u00e9rifier la conformit\u00e9 du biom\u00e9thane aux sp\u00e9cifications d\u2019injection, odoriser le gaz afin de faciliter la d\u00e9tection d\u2019\u00e9ventuelles fuites, et mesurer les volumes inject\u00e9s dans le r\u00e9seau.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n\n
P<\/span><\/div><\/div>
Oxydeur thermique<\/div>
L\u2019oxydeur thermique est utilis\u00e9 pour br\u00fbler les diff\u00e9rents flux gazeux g\u00e9n\u00e9r\u00e9s par le processus de valorisation du gaz issu des sites de stockage (notamment ceux contenant des COV), afin d\u2019\u00e9viter l\u2019\u00e9mission de polluants dans l\u2019atmosph\u00e8re.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n<\/div><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
