Processes for reducing nitrosamine formation during gas purification in amine based liquid absorption systems |
| abstract |
Acid gas purification processes for reducing nitrosamine precursor formation from a gas stream containing NOx, wherein the acid gas is selectively absorbed in an amine based wash solution comprising at least one secondary diamine. The processes generally include absorbing carbon dioxide from the gas stream containing NOx species with the amine-based wash solution comprising at least one secondary diamine to provide a carbon dioxide lean gas stream that is released into the surroundings, wherein absorbing the acid gas forms a rich amine solution; and regenerating the rich amine solution at an elevated temperature to release the carbon dioxide to form a regenerated lean amine solution, wherein absorbing and regenerating are configured to promote formation of carbamate species of at least one diamine. |
