    摘要： Process for manufacturing sodium-metal oxide by burning a mixture comprising as a first constituent compounds containing sodium (1) and, as a second constituent, compounds containing the metals aluminium, titanium or vanadium (2). The burning is accomplished by spraying the mutually mixed compounds in the aqueous phase and in dropshape into a burning chamber (6) where the combustion takes place at a temperature between 970 and 1870° K (700 and 1600° C).
    Advantageously, the compounds containing sodium are combustible sodium lignosulfonates or other sodium derivatives of lignin contained in the spent digestion liquors from the production of cellulose. Preferably, an aluminium compound is used, which is subsequently converted into sodium aluminate.

    摘要： A method is provided for treating black liquor particularly derived from nonwood pulp, by heating with an alkaline earth metal oxide in a toroidal fluidised bed reactor (304) at a temperature of above 650°C. The method may be used alone or as part of a method of converting graminaceous raw material to pulp for paper or board, said method comprising (a) digesting (12) said raw material with a white liquor based on sodium hydroxide and further comprising calcium hydroxide in an amount effective to substantially convert silica of said raw material to calcium silicate; (b) recovering (14) pulp and black liquor substantially free of uncombined silica; (c) heating the black liquor in a fluidized bed reactor (304) containing calcium oxide for catalysing conversion of organic content of said black liquor to gas and for providing recovered solids including sodium values of said white liquor and calcium oxide; and regenerating said white liquor using said recovered solids. The use of the above mentioned white liquor permits treatment of wheat straw, rice straw and other high-silica materials (9) without resulting in a black liquor that is difficult to treat.

    摘要： Sodium hydroxide is recovered from an alkaline waste liquor ("black liquor") containing substantially no sulfur compounds discharged from a process comprising soda cooking wood fibers, washing and optionally bleaching them, by a direct causticization process. This process comprises:

    (a) adding a gas comprising carbon dioxide to the black liquor as it is or after concentration to adjust the pH of the black liquor to 9.5 to 12.5 (determined at a black liquor solids concentration of 40% and 80°C),
    (b) concentrating the above described black liquor to a solids concentration of 50 to 95%,
    (c) adding the above described carbon dioxide-treated and concentrated black liquor, oxygen and iron oxide to a combustion furnace, subjecting the mixture to combustion and thus burning organic substances and converting inorganic soda components into sodium carbonate and sodium carbonate into sodium ferrite, and
    (d) hydrolyzing the thus resulting product to recover sodium hydroxide and recycling the recovered iron oxide to step (c).

    摘要： The present invention relates to a method and arrangement for separating contaminants from liquids, such as condensates, or vapors at an evaporation plant. Contaminants are separated from liquids by stripping when bringing a contaminant-enriched liquid into direct contact with a vapor by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus reducing the contaminant-content of the sprayed liquid and producing a cleaner liquid. The contaminants are enriched in the vapor. From vapors contaminants are separated by absorption when bringing a contaminant-enriched vapor into direct contact with a cleaner liquid by spraying or distributing the liquid into the vapor flowing in a vapor duct or onto wall surfaces in the vapor duct thus increasing the contaminant-content of the liquid, but producing a cleaned vapor.
