Abstract
A carbon dioxide (CO) chemical absorption system comprising: a COabsorption column for separating COfrom combustion exhaust gas by absorbing the COin the combustion exhaust gas with a COabsorbing liquid mainly composed of an aqueous alkanolamine solution; a regeneration column for regenerating the COabsorbing liquid by desorbing COgas from the COabsorbing liquid that has absorbed CO; a condenser for condensing water vapor entrained in the desorbed COgas discharged from the top of the regeneration column, thereby obtaining reflux water; a pipe for returning all or part of the reflux water obtained by the condenser to the top of the regeneration column, and dispersing the reflux water in the regeneration column; a collection plate for collecting the reflux water dispersed in an upper portion of a packed bed in the regeneration column; a pipe for sending the regenerated COabsorbing liquid from the bottom of the regeneration column to the top of the absorption column; and a pipe for joining the reflux water collected by the collection plate into the pipe for sending the regenerated COabsorbing liquid.
