RECOVERY OF HIGHLY FLUORINATED CARBOXYLIC ACIDS FROM THE GASPHASE |
摘要 |
Recovery of highly fluorinated carboxylic acids from the gas phase Highly fluorinated carboxylic acids can be removed from exhaust gas streams by scrubbing with concentrated alkali solutions if these alkali solutions have a density high enough for the salt of the highly fluorinated carboxylic acid to separate out as an independent phase. An apparatus suitable therefor contains a scrubber and a separation vessel which is advantageously equipped with a conveying element, a collection vessel connected via an overflow and a circulation line for the scrubbing liquor.
