Cooling process associated with a process using anhydric hydrofluoric acid |
| abstract |
SHORT COOLING METHOD ASSOCIATED WITH A METHOD USING ANHYDROUS FLUORHYDRIOUE ACID This process is intended to evacuate at least part of the heat produced in at least one reaction and / or operation purification involving anhydrous HF, cooling dissement being carried out by heat exchange with a coolant circulating in a circuit which includes at least one exchange zone (9; 10; 11) having risk of HF leaking into the coolant sement. As such fluid, an aqueous solution is used at least one compound chosen from (a) strong bases; (b) the salts resulting from the combination of a strong base and an organic or mineral acid with a pKA of>3.5; (c) salts of amphoteric oxides with bases; (d) the compounds which, in contact with water, transform into one the above-mentioned compounds; said fluid is circulated closed circuit cooling; and we work with a coolant pressure lower than pressure at which the reaction is carried out and / or the purification operation. |
