FIELD: inorganic compounds technology. SUBSTANCE: production of carbon dioxide from smoke fumes involves removal of sulfur dioxide from the latter, adsorption on zeolite sorbent and subsequent desorption of carbon dioxide, drying by silica gel, purification, and regeneration of sorbents. Desorption is accomplished by heating sorbent to desorption temperature. By-product, namely dried nitrogen gas, is obtained during carbon dioxide adsorption stage, for the purpose of which drying of smoke fumes and simultaneous removal of sulfur dioxide therefrom are performed before adsorption of carbon dioxide. Zeolites, prior to be heated for regeneration, are purged with commercial carbon dioxide at ambient temperature until nonadsorbable impurities are completely removed. Regeneration is accomplished by purging sorbent with earlier obtained dried nitrogen gas. EFFECT: reduced power consumption, reduced price cost of carbon dioxide, and prevented pollution of atmosphere. 3 cl, 1 dwg
