FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Ammonia solution is used to remove carbon dioxide from flue gases of a fossil-fuel power plant. The flue gases are desulphurated, cooled and CO2 is absorbed therefrom. Water is trapped along with carbon dioxide gas from flue gases, which is an advantage for using the method in areas with a hot climate, and fertiliser - (NH4)2SO4 - is obtained.
EFFECT: high efficiency of removing carbon dioxide.
