METHODS FOR INHIBITING SOLVENT EMISSIONS

A method for reducing the loss of solvent during carbon dioxide capture from flue gas in an amine based solvent process by the steps of feeding a flue gas containing carbon dioxide to an absorber column containing an amine solvent; absorbing carbon dioxide in the amine solvent forming a rich solvent...

Beschreibung
Zusammenfassung:	A method for reducing the loss of solvent during carbon dioxide capture from flue gas in an amine based solvent process by the steps of feeding a flue gas containing carbon dioxide to an absorber column containing an amine solvent; absorbing carbon dioxide in the amine solvent forming a rich solvent; feeding the rich solvent to at least one inter-stage cooler; recovering the rich solvent and feeding the rich solvent to a regeneration column; separating the carbon dioxide from the rich solvent and recovering the carbon dioxide to form a lean solvent; feeding the lean solvent to the absorber column. The improvement is realized by one of feeding steam to the flue gas; feeding steam to the absorber column after introduction of amine solvent; feeding the flue gas stream to a demister before feeding to the absorber column or increasing the lean solvent inlet temperature into the absorber column.
