| titleOfInvention | Method for separating and recovering hydrogen fluoride |
| abstract | THIS INVENTION RELATES TO A METHOD FOR RECOVERING HYDROGEN FLUORIDE FROM A GASEOUS MIXTURE CONTAINING HYDROGEN FLUORIDE AND IMPURITIES BY CONTACTING THE GASEOUS MIXTURE WITH AT LEAST ONE OF ABSORPTIVE LIQUIDS THEREBY TO ABSORB SAID HYDROGEN FLUORIDE INTO SAID ABSORPTIVE LIQUID AND THEN RECOVERING SAID HYDROGEN FLUORIDE BY HEATING THE RESULTANT ABSORPTIVE LIQUID UNDER EVAPORATION. THE HYDROGEN FLUORIDE THUS RECOVERED HAS HIGH PURITY. THE ABSORPTIVE LIQUIDS INCLUDE PHOSPHORIC ACID, POLY-PHOSPHORIC ACID, FLUORO-PHOSPHORIC ACID OR MIXTURES THEREOF. ALSO THE ABSORPTIVE LIQUIDS MAY CONTAIN SULPHURIC ACID AND FLUOROSULPHURIC ACID IN ADDITION TO THE PHOSPHORIC ACID, POLYPHOSPHORIC ACID, FLUORO-PHOSPHORIC ACID AND THE MIXTURES THEREOF. |
