Absorbing solution and recovery method for carbon dioxide |
| abstract |
A method for the recovery of carbon dioxide (CO2) which comprises: bringing, in an absorption tower, a gas to be treated into contact with a CO2-absorbing solution set forth in claim 1 to form a CO2-rich solution, said gas containing both CO2 and oxygen; circulating the CO2-rich solution in a regeneration tower to heat and discharge the CO2 and thus recover the same; returning the obtained CO2-poor solution to the absorption tower; and conducting heat exchange between the solution transferred from the absorption tower to the regeneration tower and the solution returned from the regeneration tower to the absorption tower. The method is characterized by: adding either a silicone oil and/or an aqueous alkanolamine solution in which an organosulfur compound represented by general formula (A) or (B) is dissolved to the solution present in the absorption tower and/or the solution returned from the regeneration tower to the absorption tower; and controlling the composition of the absorbing solution present in the absorption tower in a manner that makes the content of the alkanolamine falls within the range of 30 to 60wt%, that makes the content of the organosulfur compound falls within the range of 0.01 to 2wt%, and that makes the content of the silicone oil falls within the range of 5 to 100ppm (by weight). |
