SYSTEM FOR REMOVAL OF CARBON DIOXIDE FROM EXHAUST GAS

Title:

SYSTEM FOR REMOVAL OF CARBON DIOXIDE FROM EXHAUST GAS

Document Type and Number:

WIPO Patent Application WO/2024/019449

Kind Code:

A1

Abstract:

The present invention relates to a system for the removal of carbon dioxide from exhaust gas, the system including: a dust collector that receives exhaust gas emitted from an exhaust gas source and removes dust from the exhaust gas; a carbon dioxide absorption tank that receives the exhaust gas passing through the dust collector, reacts with a carbon dioxide absorbent containing a sodium hydroxide solution to remove carbon dioxide and sulfur oxides from the exhaust gas, and discharges the treated gas; a primary settling tank that receives the reaction liquid from the carbon dioxide absorption tank and precipitates impurities through a coagulation reaction with a coagulant; and a secondary settling tank that receives the reaction liquid from the primary settling tank and reacts with calcium oxide to recover calcium carbonate.
