Process for the continuous recovery of hydrogen fluoride gas |
| abstract |
A continuous process for the recovery of anhydrous hydrogen fluoride gas by contacting an aqueous solution of an alkali metal fluoride in hydrofluoric acid with a sulfur-containing dehydrating stream. The dehydrating stream preferably consists of sulfur trioxide dissolved in sulfuric acid. The desired product is obtained in high yield and purity. |
