Removing water and salts from a catalyst regenerator to maintain the catalytic activity

摘要

A process of drying and purifying a gas flowing to a vessel for regenerating a catalyst endonde vessel regeneration catalyst comprises a molecular sieve; elproceso comprising: a) introducing a heated regeneration gas moderately in a refrigerant, wherein the gas includes one or more deregeneración air, or air diluted with nitrogen or carbon dioxide; b) then cooling said regeneration gas to a temperature at which a substantial portion of said gas contenidode water is condensed and removed from said regeneration gas; c) then sending said regeneration gas to a scrubber; d) then passing a quantity of water through said scrubber to remove salts from said gas deregeneración and e) sending said regeneration gas to said catalyst regeneration vessel comprising dichocatalizador molecular sieve.
