Patent ID: 6866787

Claim:
A process for drying wet F32, which comprises placing a stream of the said F32 in continuous contact with a food stock of a composition comprising a molecular sieve selected from a 3A, 4A or 5A type sieve, at a first temperature of between 5 and 78° C. and at a first pressure of between 0.6 and 25 atm, wherein she sieve feed stock is regenerated by the process which consists in passing a stream of an inert gas over the feed stock, at a second pressure at about atmospheric pressure: (i) at a second temperature between 70° C. and 170° C., for the time required to remove at least 80%, of the initial amount of F32 absorbed in the feed stock, and then (ii) at a third temperature between 180° C. and 300° C., for the time required to remove at least 90%, of the initial amount of water absorbed in the feed stock.
