FIELD: process engineering.
SUBSTANCE: invention relates to complex treatment of various industrial gas emissions, particular flue gases. Proposed comprises pumping flue through tank filled with 5.0-10.0 M water solution of trifluoroacetic acid saturated with oxygen, separation of formed by-products, recovery of the latter, regeneration of used water solution of trifluoroacetic acid by saturated with oxygen and recirculation regenerated solution to pumping.
EFFECT: gas cleaning is less aggressive medium, higher absorption capacity of the latter, simplified process.
