Abstract: A novel method and apparatus for removing fluorine compounds from solutions formed in the concentration of "wet-process" phosphoric acid is disclosed, characterized by (1) contacting the exit vapor stream from a phosphoric acid concentrating stage with a scrubbing liquor that is sprayed into the vapor exit duct of the phosphoric acid concentrator, (2) draining a liquid fraction from the exit duct that contains condensed fluorine compounds, and (3) passing the remaining exit vapor stream/sprayed scrubbing liquor mixture into a cyclonic-type entrainment separator where the entrained scrubbing liquor and condensed fluorine compounds are separated from uncondensed vapors, with the uncondensed vapors passing to a barometric condenser where additional separation impurities by condensation is effected. In one embodiment identified as "single stage FSA recovery" the vapor exit duct from the acid concentrator is connected to an entrainment separator and the scrubbing liquor is contacted with the evaporator exit vapor stream by spraying the liquor into the vapor exit duct via a series of spray heads. In a second preferred embodiment identified as "dual stage FSA recovery", the entrainment separator is replaced by a novel scrubber/entrainment separator apparatus and a second array of spray heads is used to introduce additional scrubbing liquor into the scrubber/entrainment separator apparatus. The invention may be utilized in an acid concentrating process comprising one or more vacuum concentrating stages.

Abstract: A one-trip assembly that includes the mill or mills for milling a window, the whipstock, the whipstock anchor or packer, and a valving assembly is disclosed which permits running in all the equipment needed for setting and orienting a whipstock and squeezing cement below the whipstock in one trip. Valving is provided which allows for the squeezing to go on after the whipstock packer is set. A feedback technique to determine that the milling assembly been pulled away from the cementing tube is incorporated into the assembly. In one embodiment, upon initiation of milling, pressure differential is used to shift a tube for valve actuation, effectively isolating the squeezed formation from pressures above the whipstock. In another embodiment, the whipstock is shifted to actuate an upper flapper. A second flapper valve is provided, preferably below the whipstock packer, which, responsive to pressure from below, is urged into a closed position, The onset of milling breaks out shear plugs that were installed in the mill nozzles to facilitate the initial squeeze cementing process through a cementing tube. Milling then proceeds in the normal manner.
