AIR CONTAMINATION MONITORING SYSTEM Russian patent published in 2016 - IPC B01D53/14 B01D53/62 

FIELD: ecology.

SUBSTANCE: invention relates to air contamination monitoring system. System has unit for CO₂ extraction comprising CO₂ absorber, in which CO₂ contained in boiler flue gas is removed by means of amine absorbent and absorbent regenerator, where absorbent regeneration is performed, wherein CO₂ absorber is equipped with CO₂ absorption section, where CO₂ contained in flue gas is absorbed by means of amine absorbent, and section of filters of water-repellent material, which is placed on side downstream of flue gas movement from CO₂ absorption section and catches amine absorbent mist taken by flue gas not containing CO₂, wherein section of filters from water-repellent material includes housing for filters, containing chamber for gas inlet, in which flue gases not containing CO₂ are lifted from CO₂ absorption section, and multiple filters from water-repellent material, installed on filters body side surface to provide passage of inlet flue gas not containing CO₂ through said filters in direction orthogonal to gas flow direction.

EFFECT: invention provides reduction of amine absorbent loss at discharge of flue gas wherefrom CO₂ is removed.
