Recovery of methane from land fill gas. |
摘要 |
<p>High purity methane and carbon dioxide are recovered from landfill gas in an integrated multi-column adsorption system having a temperature swing adsorption section (TSA) for pretreatment of the crude landfill gas to remove trace impurities therefrom, the thus cleaned gas being fed to a pressure swing adsorption section (PSA) for bulk separation of CO2 from methane. Regeneration of the impurity-laden adsorbent bed of the TSA section is carried out using part of the CO2 product gas recovered from the PSA section which gas is heated to thermal regeneration temperature.</p> |
