FIELD: chemistry.
SUBSTANCE: water washing unit includes first and second stages. Method includes the following stages: obtaining saturated CO2 liquid, which contains CO2, dissolved in liquid; obtaining liquid for water washing; combination of CO2-saturated liquid with liquid for water washing, which results in formation of CO2-enriched liquid for water washing, with the following introduction of liquid into water washing unit; and bringing said gaseous products of burning in contact with said CO2-enriched liquid for water washing in said water washing unit in each first and second stages; and obtaining flow of gaseous products of burning with reduced content of ammonia and flow of waste washing water.
EFFECT: improved ammonia trapping from processed gaseous products of burning in absorption system.
