FIELD: process engineering.
SUBSTANCE: proposed method comprises producing hydroxide in water and mixing it with gas flow to produce carbonate and/or bicarbonate in process carried out in two separate chambers wherein one chamber is used for production of carbonate products and another one for production of bicarbonate products or mix of both. Proposed unit comprises electrolysis chamber for production of hydroxide and mixers to mix hydroxide with gas flow including carbon dioxide to obtain carbonate an/or bicarbonate.
EFFECT: efficient extraction of carbon dioxide, undesirable admixtures in flue gases and product of useful bypass products.
