Process for the recovery of perfluorinated sulphonic acids from spent acid |
abstract |
Method for the recovery of a fluorinated sulphonic acidnfrom a spent acid product by steps ofn subjecting the spent acid product to thermal treatment tonobtain the acid in its active form and a residue, and separating the active acid from the residue by strippingnwith a stripping agent, comprising the further steps of separating the striping agent from the active acid by distillationnand withdrawing the separated stripping agent. |
