| titleOfInvention | COOLING PROCESS ASSOCIATED WITH A METHOD USING ANHYDROUS HYDROCHLORIC ACID. |
| abstract | This process is intended to remove at least part of the heat produced in at least one reaction and / or purification operation involving anhydrous HF, the cooling being carried out by heat exchange with a cooling fluid circulating in a circuit. which comprises at least one exchange zone (9; 10; 11) presenting a risk of HF leakage into the cooling fluid. As such a fluid, an aqueous solution of at least one compound chosen from (a) strong bases is used; (b) salts resulting from the combination of a strong base and an organic or inorganic acid whose pKA is> 3.5; (c) salts of amphoteric oxides with bases; (d) compounds which, on contact with water, transform into one of the aforementioned compounds; said cooling fluid is circulated in a closed circuit; and one works with a cooling fluid pressure lower than the pressure at which the reaction and / or the purification operation are carried out. |
