FIELD: process engineering.
SUBSTANCE: invention can be used in chemical and petrochemical industries. Air fed into apparatus of reclamation of zeolite or nonzeolite molecular sieve catalyst is cleaned of metal salts. First, initial air is cooled to remove air in condenser and, then rinsed in scrubber to remove, is fact, all salts from said initial air. Preferably, water removed at cooling stage is recirculated to remove salts from initial air.
EFFECT: longer life.
