SINGLE-BED RADIAL ADSORBERS IN SERIES |
摘要 |
The invention relates to a method for purifying a feedstock gas flow including a main compound, water (H2O) and carbon dioxide (CO2) as well as so-called secondary impurities, that comprises: a) feeding the feedstock gas flow into at least one 2-grid radial adsorber comprising as a single adsorption bed an activated alumina or silica gel bed on which H2O is preferably adsorbed; b) feeding the gas resulting from step a) into at least one 2-grid radial adsorber comprising as a single adsorption a molecular sieve bed on which CO2 and secondary impurities are preferably adsorbed; and c) recovering a gas resulting from step b) enriched with the main compound and suitable for cryogenic distillation.
