摘要： Contaminated adsorbent particles, preferably activated carbon particles, are regenerated in water at supercritical conditions. The particles are preferably mixed in water prior to treatment. The mixture is preferably heated to a temperature at least about 900 °F (482 °C) and pressurized to a pressure sufficient to achieve supercritical conditions for water. The mixture is preferably flowed through a first reactor for a time sufficient to substantially remove the organic contaminants from the particles. The particles are separated from the water and the mixture of water and organic contaminants may be transferred to a second reactor. Within the second reactor the organic contaminants are preferably substantially oxidized by supercritical water oxidation.

Date Jun. 23, 1994An absorption machine and a method for operating the machine are disclosed. The absorption machine comprises an absorber (1) with heat-exchanger assemblies and a generator (2) with heat-exchanger assemblies, the generator (2) and the absorber (1) being interconnected by two conduits (8, 9). The absorber (1) and/or generator (2) are divided into at least two compartments which are in communication with one another and in which the different heat-exchanger assemblies have separate inlets and outlets. By means of the inventive machine, heating media of different temperatures can be obtained from the absorber (1) and waste heat of different temperatures can be used in the generator (2).

摘要： A process for treatment of waste containing organic material, phosphorous and water in suitable amounts to be a pumpable sludge and in order to be oxidizable through supercritical water oxidation, comprises the steps of: putting the sludge into conditions being supercritical for water; adding oxidant, particularly, oxygen to the sludge, wherein the organic material contained in the waste is substantially completely oxidized by means of supercritical water oxidation; separating the phosphorous from water and from carbon dioxide formed during the oxidation; and recovering the phosphorous by means of dissolving the phosphorous in an alkali.

摘要： A reactor for supercritical water oxidation comprises an essentially vertical reactor section (11) and an essentially non-vertical reactor section (12), wherein the vertical reactor section has a cross-sectional area which is substantially larger than the cross-sectional area of the non-vertical reactor section. The vertical reactor section has an inlet (14) in an upper portion thereof for receiving (17) a flow containing organic material and water, and an outlet (16) in a lower portion thereof for outputting (20) the flow. Both the vertical and the non-vertical reactor sections are configured to oxidize organic material in the flow through supercritical water oxidation.

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： A method for supercritical water oxidation comprises the steps of: causing a first process stream containing water and organic material to flow in a reaction chamber (11); adding a first flow of oxidant to the first process stream in stoichiometric shortage; reacting the organic material in the first process stream with the oxidant; adding a second process stream containing water and organic material to the reacted first process stream, the second process stream having a temperature which is lower than a temperature of the first process stream to thereby reduce a temperature in the reaction chamber; adding a second flow of oxidant to the process streams; and reacting organic material in the first and second process streams with the second flow of oxidant.
