Abstract
Methane-containing gases with an appreciable content of carbon dioxide are scrubbed with cold methanol to remove the bulk of the carbon dioxide in a simple system comprising a single gas-liquid contact column and featuring regeneration of the methanol containing carbon dioxide solely by multiple-stage flashing. Land-fill gases containing methane and carbon dioxide as the principal components can be economically processed in such a system to yield methane-rich fuel gases.
