Process for removing lighter volatile impurities from gases |
摘要 |
Lighter volative impurities are removed from gases by drawing the gas to be purified into a vacuum system. The gas to be purified deposits onto the cold surface of a condenser which is at cryogenic temperatures, while the lighter volatile impurities are continuously pulled out of the vacuum system in gaseous form.
