摘要： The invention relates to a method for making purified methanol from a liquefied fraction obtained from a sulfate pulp process and containing methanol and sulfur contaminants, its main sulfur contaminants being methyl mercaptan, dimethyl sulfide and dimethyl disulfide. According to the invention, the fraction is subjected to an oxidation treatment, followed by separating the methanol by distillation or water vapor distillation from distillation residue containing sulfur-bearing oxidation products. From the distillation residue can be crystallized dimethyl sulfone produced in oxidation and obtained as a by-product of the process.

摘要： The invention relates to a method for making dimethyl sulfone. According to the invention, dimethyl sulfone is manufactured by oxidation from dimethyl sulfide in a methanol-based medium. Methanol is removed during and/or after the oxidation by distillation, water vapor distillation or evaporation, and finally dimethyl sulfone is crystallized from a water-based solution phase. The starting material for the production process can be a liquefied fraction obtained from a sulfate pulp process, the fraction containing methanol and dimethyl sulfide, whereby the process produces not only dimethyl sulfone but also purified methanol. The invention covers also the use of dimethyl sulfone, produced according to the method, in an orally ingested health formulation or in an externally used therapeutic formulation, such as a skin cream.

摘要： The patent claims concern a method for a more efficient 'wet combustion' of COD-containing effluents from industrial processes and municipal plants and for a more efficient COD-reduction by enzymes in aerobic and anaerobic biological cleaning processes and for same sorts of effluents. The method implies a strong increase of the reaction speed between added oxygen and the elements in the liquid to be oxidized through so-called 'Turbo Oxidation', which implies that the liquid is submitted to strong movements and turbulence during several circulations within one or more liquid circuits during continuous addition of oxygen. By the same method, COD reduction by enzymes can also be made more effective. The single circuit is placed in connection to and communicates liquid-wise with a pressurized reaction tank, from where the developed reaction gases are continuously let out. Into the circuits and the attached reaction tank is continuously fed controlled quantities of the liquid to be oxidized together with proportionate quantities of oxygen or enzymes. Concurrently, the outlets of respectively oxidized liquid and evolved gases are controlled automatically. Out-going, oxidized liquid can be heat exchanged against in-going liquid, and the hot gases from the reaction tank can be used for external, heating purposes.

摘要： Pour la fabrication de la cellulose à partir de bois et de plantes annuelles, on propose un procédé de mise en ébullition dans lequel la liqueur d'ébullition comporte une lessive de soude libre et le cas échéant des sels sodés des acides alkylbenzènesulfoniques ou des acides carboxyliques aromatiques et aliphatiques. Par addition d'anthraquinone ou de dérivés de cette substance dans la liqueur d'ébullition, on renforce la délignification. Il n'est plus nécessaire de limiter les quantités d'hydroquinone ajoutées, en raison du prix de cette substance, du fait que l'anthraquinone résiste à l'oxydation par voie humide et peut être réutilisée dans le processus de mise en ébullition. La solubilité et par conséquent l'action de l'anthraquinone sont augmentées grâce à l'utilisation de sels de l'acide sulfonique. Pour récupérer les produits chimiques d'ébullition présents dans la liqueur noire, il est proposé de précipiter la lignine présente dans la solution avec un acide minérale ou un acide carboxylique, le cas échéant, de séparer les hémicelluloses par ultrafiltration et les résines par extraction et de brûler les composés organiques restants autres que les sels de l'acide sulfonique et les sels de l'acide carboxylique par oxydation en phase aqueuse avec de l'air et/ou de l'oxygène. La solution de produits chimiques libérée par les produits de la décomposition du bois peut être réintroduite dans la liqueur, après caustification des carbonates, et mise à disposition, après une cristallisation partielle des sels aliphatiques de l'acide carboxylique, dans le circuit de production de cellulose. L'acétate de sodium isolé par cristallisation peut être dissocié en acide acétique et en hydroxyde de sodium par électrolyse réalisée avec une membrane. La lessive de soude est réintroduite dans le processus de cuisson et l'acide acétique est traité séparément.

摘要： Organic constituents in a liquid, such as a waste water from a municipal or industrial process (e.g. bleach plant extraction liquor from the bleaching of paper pulp) may proceed effectively without the addition of alkali. When the organic constituents are reacted with an oxygen containing gas at appropriate pressure and temperature conditions, oxidized organics and gaseous acidic products of oxidation (e.g. CO₂) that are produced are continuously and immediately removed from the liquid so that they do not significantly contribute to lowering of the pH of the liquid, so that the reaction may proceed and the liquid remain alkaline.
This may be accomplished in a gas sparged hydrocyclone (40) in which the liquid is introduced into the first end (41) of a vortex (59) while oxygen is introduced from exteriorly of the vortex (at 49) into contact with the liquid, or may be accomplished by causing the liquid to flow in a thin film in a downwardly extending spiral path (19) and removing the acidic gases from a center portion (32) of the spiral path. A reactor (16) for effecting the last mentioned procedure includes a pressurized vertical vessel having a downwardly extending stationary spiral surface mounted in the vessel substantially concentric with it. Surface manifestations (29) may be provided on the spiral surface for enhancing mixing of liquid with surrounding gas (Figure 1).
摘要翻译：液体中的有机成分，例如来自市政或工业方法的废水（例如漂白纸浆漂白植物提取液）可以有效地进行而不加碱。当有机成分在适当的压力和温度条件下与含氧气体反应时，所生成的氧化有机物和氧化的气态酸性产物（例如CO 2）从液体中连续并立即除去，使得它们不显着地有助于降低的液体的pH值，使得反应可以进行并且液体保持碱性。这可以在气体喷射式水力旋流器（40）中完成，其中液体被引入到涡流（59）的第一端（41）中，同时从涡流（在49处）从外部引入氧气与液体接触，或者可以通过使液体以向下延伸的螺旋路径（19）中的薄膜流动并从螺旋路径的中心部分（32）去除酸性气体来实现。用于实现最后提到的过程的反应器（16）包括加压的垂直容器，其具有安装在容器中的与其基本同心的向下延伸的固定螺旋表面。可以在螺旋表面上提供表面表现（29），以增强液体与周围气体的混合（图1）。
