Abstract:
1. A process for producing high purity acetylene comprising: withdrawing a stream comprising acetylene and impurities from a storage source, said impurities comprising moisture and solvent; providing an adsorbent bed containing adsorption media, said adsorption media comprising at least a first adsorption medium, a second adsorption medium and a third adsorption medium; passing said stream through said first adsorption medium to selectively remove moisture from said stream, thereby producing a first partially purified stream; passing said first partially purified stream through said second adsorption medium to selectively remove solvent from said first partially purified stream, thereby producing a second partially purified stream, said second partially purified stream containing other impurities, said other impurities comprising carbon dioxide; and passing said second partially purified stream through said third adsorption medium to selectively remove carbon dioxide from said second partially purified stream, thereby producing said high purity acetylene.
