PROCESS AND APPARATUS FOR REMOVAL OF VOLATILE DEGRADATION PRODUCTS FROM ABSORPTION CIRCUIT OF A CO SEPARATION PROCESS Russian patent published in 2016 - IPC B01D53/14 B01D53/62 B01D53/96 

FIELD: technological processes.

SUBSTANCE: invention relates to a method for extracting highly volatile degradation products from absorbent loop of a carbon dioxide separation process. Method comprises directing adsorbent substance, which is an aqueous solution of a secondary amino acid salt, into circuit with an absorbent substance which comprises technological process of absorption and desorption process, wherein condensate is extracted during condensation process that is performed after desorption process, and then cleaned from degradation products, resulting in formation of purified condensate, that is again supplied back to circuit with an absorbent substance.

EFFECT: invention provides removal of degradation products and degradation with low consumption of electric energy from circuit with adsorbing substance for separation of carbon dioxide, not degrading properties of absorbent solution.
