The present invention relates to an apparatus and method for recovering carbon dioxide (hereinafter also referred to as 'CO') contained in a combustion exhaust gas, and more specifically relates to: an apparatus and method for reactively absorbing COcontained in a combustion exhaust gas into an amine compound-containing absorption liquid; an apparatus and method for desorbing COcontained in an amine compound-containing absorption liquid from the amine compound-containing absorption liquid; an apparatus and method for evaporating and separating impurities from the amine compound-containing absorption liquid containing the impurities; an apparatus and method for performing a pretreatment such as desulfurization, dust removal, and cooling on a combustion exhaust gas; and a carbon dioxide-recovering apparatus and method utilizing the above apparatuses and methods.

Apparatus and method for recovering carbon dioxide in combustion exhaust gas

A mixing element in which spiral blade edge portions are disposed in a tube wall portion of a passage tube through which fluid flows and an opening section of the passage tube and the blade edge portions are joined to each other is provided. In an existing manufacturing method using a gas welding machine, when, for example, a mixing element having an inside diameter of 130 mm is to be manufactured, eight 90-degree rotation type spiral blades can be disposed at most. In a method for manufacturing the mixing element according to the present invention, it is possible to manufacture a mixing element including 10 or more blades by using a laser processor.
