FIELD: gas purification.
SUBSTANCE: invention relates to the field of purification of gas mixtures from carbon dioxide impurities and can be used in various fields of science and technology. The gas stream to be cleaned is bubbled using a divider through a suspension of finely crushed carbonate of at least one alkaline earth metal while stirring the suspension solution in a bubbling chamber. The specified suspension saturated with carbon dioxide is filtered on a dynamic filtration unit through a rotating membrane filter in the ultrasound field. The filtrate is placed in the degassing chamber, and the unfiltered part is returned to the bubbling chamber.
EFFECT: invention provides an increase in the efficiency of carbon dioxide extraction from gas mixtures.
