摘要： For the production of cellulose from wood and annual plants, a boiling process is proposed in which the boiling liquor contains free soda lye and sodium salts of the alkylbenzole sulphonic acids or aromatic and aliphatic carboxylic acids. Delignification is reinforced on the addition of anthraquinone or its derivatives to the boiling liquor. There is no need to restrict the quantities of the anthraquinone additive owing to its price since anthraquinone resists wet oxidation and can be recycled in the boiling process. The solubility and hence the effect of the anthraquinone is enhanced by the use of sulphonic acid salts. In order to recover the processing chemicals contained in the black liquor it is proposed that the dissolved lignin be precipitated with mineral or carboxylic acid, the hemi-celluloses be separated by ultra-filtration and the resins by extraction, where appropriate, and the remaining organic components except for the sulphonic and carboxylic acids salts be burned in the aqueous phase with air and/or oxygen. The chemical solution freed from the wood decomposition products may be returned to the liquor after caustification of the carbonates and, after the partial crystallisation of the aliphatic carboxylic acid salts, made available in the circuit for cellulose production. The sodium acetate isolated by crystallisation can be broken down into acetic acid and sodium hydroxide by diaphragm electrolysis. The soda lye is returned to the boiling process and the acetic acid treated separately.

摘要： A process for recovering inorganic material from an effluent suspension produced in the treatment of waste paper. The effluent suspension, in the form of an aqueous suspension containing at least 2% by weight of dry solids, is contacted with an oxygen-containing gas at an elevated temperature, and at an elevated pressure sufficient to keep the water component of the sludge in the liquid phase, for a time sufficient to effect substantially complete oxidation of the organic material in the suspension. The resulting product is dewatered and then resuspended in water, whereafter there is separated from the suspension water containing fine carbon particles in suspension to leave the desired inorganic material.

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.
摘要翻译：该专利主张涉及一种更有效的“湿燃烧”来自工业过程和市政工厂的含COD流出物的方法，以及通过好氧和厌氧生物清洁过程中以及相同类型的流出物中的酶更有效地减少COD的方法。该方法意味着通过所谓的“涡轮氧化”在所加入的氧气与要被氧化的液体中的元素之间的反应速度的强烈增加，这意味着液体在一次或多次循环期间经受强烈的运动和湍流在连续加入氧气期间的液体回路。通过相同的方法，酶的COD降低也可以更有效。单个回路与加压反应罐液体连接并与其连通，从反应罐中连续排出反应气体。向所述回路和所连接的反应罐中连续地供应控制量的待氧化的液体以及成比例量的氧气或酶。同时，分别氧化的液体和放出的气体的出口被自动控制。外出的氧化液体可以与正在进行的液体进行热交换，并且来自反应罐的热气体可以用于外部加热目的。

摘要： The capacity of a chemical recovery plant for alkaline black pulping liquors is increased by diverting a portion (38) of the black liquors (1) to a wet oxidation step (39). Organic material is oxidized and water is evaporated. The resulting oxidized black liquor (42) is combined with unoxidized black liquor (43) to produce a black liquor mixture (44,50) of reduced volume and a higher ratio of pulping chemicals to organic matter. The liquor mixture (50) is burned in a recovery furnace (52) at an increased rate.

摘要： Procédé pour brûler directement dans l'eau des matériaux organiques dissous ou finement dispersés à l'aide d'oxygène moléculaire sous une pression élevée et à une température variant entre 180oC et 340oC. La combustion se produit en au moins deux étapes. Pendant la première étape, la combustion est menée jusqu'au point où jusqu'à 95 % de la chaleur de combustion du matériau organique est libérée. Pendant la deuxième étape, les matériaux organiques moins sensibles à l'oxydation restant dans l'eau sont brûlés en présence d'un grand excédent d'oxygène moléculaire, et le mélange de gaz et de vapeur qui se dégage pendant cette deuxième étape revient à la première étape, seul ou après addition d'oxygène moléculaire supplémentaire, de sorte que la teneur en oxygène moléculaire du mélange de vapeur et de gaz soit suffisante pour effectuer la combustion du matériau organique entrant dans ladite étape jusqu'au degré susmentionné de combustion.
