VERFAHREN UND VORRICHTUNG ZUR REINIGUNG UND ANREICHERUNG VON DEPONIEGASEN

For purification, the landfill gas is passed successively through two adsorbers (6, 41 or 7, 42) or adsorber beds (73, 74 or 75, 76); in the first adsorber, aromatics and other high-boiling impurities are separated off, and the medium- and low-boiling impurities are separated off in the further adso...

Zusammenfassung:For purification, the landfill gas is passed successively through two adsorbers (6, 41 or 7, 42) or adsorber beds (73, 74 or 75, 76); in the first adsorber, aromatics and other high-boiling impurities are separated off, and the medium- and low-boiling impurities are separated off in the further adsorber; advantageously, a device (118, 119) for separating off hydrogen sulphides is provided upstream of the actual purification unit; if the purified landfill gas is to be introduced into the gas supply network, it is advantageous to provide downstream methane enrichment (131).
