METHOD FOR SEPARATION OF WASTE GAS OR SMOKE PRODUCED IN PROCESS OF FUEL OXIDATION, AND EXTRACTION OF CARBON DIOXIDE FROM IT Russian patent published in 2009 - IPC B01D53/04 B01J20/16 B01J20/20 B01J20/34 C01B31/20 

FIELD: technological processes.

SUBSTANCE: invention may be used in chemical industry and environment protection. Waste gas flow is cooled, compressed by compressor and then passed through material that is half-permeable for gas, for instance, molecular sieve or activated coal. Adsorption and desorption of carbon dioxide in half-permeable material is carried out in compliance with adsorption technology at periodical change or swinging of temperature (AKT). Part of separated gas flow that contains highly concentrated carbon dioxide is used as initial material for production of ammonia and urea or methanol or is collected and stored for further use.

EFFECT: lower consumption of energy, reduced structural expenses and expenses on servicing.
