    摘要: A method for avoiding the precipitation of salts from a salt containing water stream prior to the stream reaching a supercritical water reactor is presented. The salt containing water stream is preferably kept at temperatures below supercritical conditions as the stream is transferred to the reactor. After the salt stream reaches the reactor the temperature of the salt stream is preferably raised to the appropriate temperature by mixing the salt stream, within the reactor, with a second stream that has been heated above the supercritical temperature of water. Alternatively, a method for preventing the clogging of the conduits upstream from the reactor may involve the mixing of two subcritical waste streams. One stream may include salts, the other preferably includes oxidizable material. The heat produced by the reaction of the oxidizable materials within the reactor preferably allows the mixture to remain at supercritical conditions for a time sufficient to oxidize substantially all of the oxidizable material.

    摘要: A method for treating waste water streams by introducing a mixture of preheated waste water and an amount of oxidant lower than that required to oxidize all the organic matter in the waste stream into the front port of an elongate tubular reaction chamber. The amount of oxidant is high enough, however, to raise the temperature of the stream in the reaction chamber to 750-1,200 °F. A first injection side port is located downstream from the front port of the reaction chamber at a distance at which the temperature has reached a maximum value, and 90-100 % of the available oxidant has been consumed. Oxidant and water are simultaneously injected through the first port, in a manner that the amount of oxidant is adequate to oxidize a specified amount of organic matter, and the amount of water is effective to counterbalance the heat produced by the reaction of the co-injected oxidant with the respective organic matter. At the point that 90-100 % of the newly injected oxidant has been consumed, a second port is used to introduce more oxidant and water in similar manner and under similar conditions. More ports are also used, following similar rules, until the organic matter has been substantially exhausted. The reaction chamber has a multiplicity of ports, so that depending on the particular stream, its BTU value, and other parameters, the appropriately spaced ports are selected as injection ports. Highly improved output is achieved by the process and apparatus of the present invention.

    摘要: A method of cleaning ventilation air that is contaminated with at least two organic solvents, wherein the ventilation air is caused to pass through fluidized beds that contain material capable of adsorbing the solvents and thereafter capable of releasing the organic substances present in the solvents by desorption. The ventilation air is caused to pass first through at least one first fluidized bed (2, 3) that contains an adsorbent material particularly suited for adsorption of one of the organic substances, and is then passed through at least one second fluidized bed (4, 5) that contains an adsorbent material particularly suited for adsorption of the other of said organic substances. The adsorbents are then tapped off separately from the first and the second beds for regeneration of the adsorbents by desorption of the organic substances, whereafter the absorbents are returned to their respective beds. The invention also relates to an arrangement for use when carrying out the method.

    摘要: Method for continuous recovery of starch from grain wherein the grain is dry milled and the flour obtained after separation of husk is mixed with water and the mixture obtained is homogenized. Directly after homogenization without intervening treatment steps the homogenized suspension is separated in a first decanter centrifugal step into a lighter fraction containing in additon to grains, solids, and fat also minor starch particles, which is removed from the process for use as feed and a heavier fraction comprising major starch particles. Said latter fraction is concentrated in a second decanter centrifugal step to a suspension having a solids content ranging from 40 to 60 %, which constitutes the final product of the process.

    摘要: The present invention relates to a method and an apparatus for removing and recovering organic substances, primarily solvents, from industrial ventilation air contaminated with such substances. The invention is based on the adsorption of solvent in an adsorbent comprising macroporous polymeric particles upon passage of the air through a movable, so-­called fluidized bed (2,3) of the polymeric particles. These particles are fed continuously through the bed under the in­fluence of the air and are then fed continuously into a desorption column (8), in which the solvent is desorbed from the adsorbent, stripped with the aid of heated air and drawn off to a cooler (14).
