    Abstract: The present invention relates to a process for reacting ammonia and wet process phosphoric acid to produce ammonium phosphates, which process comprises feeding the reagents to a vessel comprising two tubular members in fluid flow communication with one another and with a gas disengagement vessel, at least one of said tubular members being generally upright, the ammonia being fed to the basal portion of the upright member, the phosphoric acid being fed to the other tubular member; allowing the resultant reaction mixture to circulate spontaneously up the upright member, through the gas disengagement vessel and through the other member to the upright member; and recovering the ammonium phosphate reaction products from the reaction system.

    Abstract: A sparge for use in a high-pressure vessel operated at elevated temperatures and having high energy agitators for suspending mineral containing particles in a slurry. The sparge injects reagent fluids into the slurry to reduce reaction times and for controlling process parameters for extracting valuable minerals from the particles. The sparge has a vapor lock to inhibit the flow of particulate material and detritus material under low or no fluid flow situations which occur commonly in the operation of high pressure autoclaves. The sparge has a fluid flow path that increases in cross-sectional area in the direction of flow of reagent fluids so as to keep reagent fluids flowing at a velocity below a critical impingement velocity that can cause metal materials of the sparge to either wear rapidly, combust and in the worst case lead to loss of containment and violent and rapid depressurization of the high pressure vessel.

    Abstract: A reactor tank is provided having an enzyme inlet, a heating jacket positioned around the exterior center of the tank, a gas outlet for communicating with a vacuum apparatus to create a vacuum within the reactor tank and for communicating with a condensing unit, a first gas inlet for receiving gas from a feed tank and a first liquid outlet for recirculating the liquid from the first liquid outlet back to the feed tank. The reactor tank further includes a sparged unit and a screen positioned within the tank between the sparged unit and the first liquid outlet, where the sparged unit is connected to the first gas inlet for receiving gas from the feed tank. The reactor tank is utilized in a reactor system further including a condensing unit, vacuum pump or venturi valve, a first feed tank connected to the first gas inlet, a coalescer having at least one circulation pipe and a first circulation pump connected to the first liquid outlet for circulating a portion of the liquid dispelled from the liquid outlet to the coalescer, which after being filtered through coalescer is recirculated through circulation pipe back to the first feed tank.
