Abstract

En fremgangsmåte for regenerering av et brukt halogenidfluid som omfatter en tetthet større enn 1,078 kg/l (9,0 Ibs/gal) og inneholder både løselige og uløselige forurensninger. Denne fremgangsmåten omfatter trinnene av å (1) tilsette syre til det brukte halogenidfluidet slik at pH er innen et område på omkring 0 til 10,0; (2) kontakte det brukte halogenidfluidet med halogen for å øke tettheten til minst 1,198 g/cm3 (10,0 Ibs/gal), opprettholde den faktiske krystallisasjonstemperaturen av fluidet og oksidere løselige forurensninger; (3) tilsette et reduksjonsmiddel mens temperaturen justeres ti et minimum på 10°C; (4) kontakte fluidet med et alkali for å nøytralisere overskuddssyre; (5) separere alle suspenderte faste forurensninger fra fluidet.A process for regenerating a spent halide fluid comprising a density greater than 1.078 kg/l (9.0 Ibs/gal) and containing both soluble and insoluble contaminants. This method comprises the steps of (1) adding acid to the spent halide fluid such that the pH is within a range of about 0 to 10.0; (2) contact the spent halide fluid with halogen to increase the density to at least 1.198 g/cm3 (10.0 Ibs/gal), maintain the actual crystallization temperature of the fluid, and oxidize soluble contaminants; (3) adding a reducing agent while adjusting the temperature to a minimum of 10°C; (4) contacting the fluid with an alkali to neutralize excess acid; (5) separate all suspended solid contaminants from the fluid.
