Regeneration of absorbent solutions used for removing gaseous acid impurities from gaseous mixtures

摘要: Improvements in the elimination and recovery of gaseous acid impurities from a mixture containing them, by an absorbing step, wherein said is brought into contact with alkaline solution regeneration step exhausted regenerated steam stripping, absorption comprising main column secondary column, operating at higher pressure means supply outside heat, lower substantially obtained expansion column. The to be conveyed firstly one two columns it incomplete way, subsequently other where its completed.
