摘要： A method for removal of pollutants from a pulping process byproduct liquor, the method comprising injecting an oxygen-containing gas into said liquor and condensing the water vapor from the stripping gas so as to produce a condensate comprising pollutants. Also a method of controlling the flow rate and/or temperature of a pulping process byproduct liquor, the process comprising injecting an oxygen-containing gas into the liquor in a reactor, processing the liquor in a flash tank so as to create a cooled liquor and combining at a least a portion of the cooled liquor with new liquor as the new liquor enters, or while the new liquor is in, the reactor.

摘要： A process for the production of cellulose from wood and annual plants is provided where the digesting liquor contains free caustic soda, sodium salts of alkyl benzenesulfonic acids, and of aromatic or aliphatic carboxylic acids. By the addition of anthraquinone or its derivatives to the digesting liquor, the delignification is improved. Anthraquinone is resistant to wet oxidation and can be reintroduced into the digesting process. The solubility and, therefore, the effectiveness of anthraquinone is improved by the use of sulfonic acid salts. For the recovery of the digesting chemicals contained in the black liquor, solubilized liquor is precipitated with mineral acid or carbon dioxide and the hemicelluloses are separated by ultra filtration. The resins are separated by extraction with the residual organic compounds, except for the sulfonates and carboxylics, being burned in an aqueous phase with air and/or oxygen. The solution of chemicals containing no further wood decomposition products can, by caustification of the carbonates, be transformed into caustic soda and after partial crystallization of the aliphatic carboxylics used for the cycle of pulp production. The sodium acetate isolated by crystallization can, by membrane electrolysis, be split into acetic acid and sodium hydroxide. The caustic soda is reintroduced to the digesting process, while the acetic acid is treated separately.

摘要： Apparatus (10) for the two stage oxidation of white liquor. The reaction vessel includes a central first stage chamber (24) and a second stage annular outer chamber (26). Heated air is first introduced through the outer second stage chamber (26) by pipes (36) and then directed through elements (38, 40, 44) to the central first stage chamber (24) for completion of the oxidation reaction. Unoxidized white liquor with a small amount of black liquor to catalyze the process is introduced to the first stage of the reaction vessel at a temperature in excess of 185 degrees F. Oxidized white liquor is removed from the second stage chamber and air is venter to atmosphere through the stack at the top of the first stage chamber. The second stage is preferably pressurized for greater efficiency.

摘要： A partially-oxidized spent pulping liquor is produced which is added to unoxidized strong spent pulping liquor prior, during, or subsequent to concentration to form a novel partially-oxidized, concentrated, high total solids spent pulping liquor. This novel, partially-oxidized, concentrated spent liquor is capable of being combusted in a spent liquor recovery furnace without the addition of auxiliary heating fuel with a resultant increase in the effective capacity of that furnace.

摘要： Sodium sulfide or sodium hydrosulfide is oxidized to form sodium polysulfide and sodium hydroxide which may be further oxidized to sodium thiosulfate and sodium hydroxide. The oxidant is air, oxygen or oxygen in mixture with other gases, the reductant is aqueous sodium sulfide or sodium hydrosulfide and the reaction is carried out with both reactants in non-flooded contact with a solid catalyst material, of which a typical example is a particulate carbon treated with polytetrafluoroethylene (PTFE). The reaction is typically conducted at atmospheric pressure and without the application of heat, with the oxidant and the reductant being in interfacial contact with each other, but only, insofar as possible, at sites where both are simultaneously in contact with a catalyst which is prevented from being flooded by either the oxidant or reductant.
