  • Patent number: 8894961
    Abstract: A process for the production of sodium cyanide crystals comprising; (a) contacting impure hydrogen cyanide and sodium hydroxide in a reactor with mixing for a maximum contact time of about 5 seconds; (b) feeding the resulting mixture to a continuous evaporative crystallizer to produce a slurry of sodium cyanide crystals; (c) passing the slurry of sodium cyanide crystals from the crystallizer over a hot surface to precipitate onto the surface and remove sodium carbonate, and passing said slurry back to the crystallizer; and (d) separating the sodium cyanide crystals from the slurry.
    Type: Grant
    Filed: April 19, 2010
    Date of Patent: November 25, 2014

  • Patent number: 7699079
    Abstract: A flexible bulk container capable of transporting a first material and introducing a second material for mixing therewithin is disclosed wherein 1) said container can comprise a component of a bulk transport system further comprising a container assembly, and 2) said container includes a body defining a cavity, at least one opening, at least one vent, and a material delivery system assembly wherein a) the body is flexible and capable of positioning within the container assembly, b) the opening provides communication with the cavity, and c) the material delivery system assembly comprises at least one manifold, a portion of which is positioned within the cavity of the flexible bulk container, and said manifold includes a shell, an interior region, an inlet accessible from outside of the cavity of the flexible bulk container and at least one passageway extending from the internal region, through the shell, to, in turn, place the interior of the manifold in communication with the cavity.
