摘要： Process for recovering chemicals and energy from cellulose waste liquors preferably black kraft liquor obtained in a paper pulp sulphate process, comprising the following, three distinct and separate steps: In the first step the concentrated black liquor is gasified in a pressurized gasification reactor by so called flash-pyrolysis at 700.degree. to 1300.degree. C., normally 800.degree.-900.degree. C., whereby an energy rich gas is produced, and in which the inorganic chemicals of the black liquor are contained in the form of molten suspended droplets, mainly comprising sodium carbonate and sodium sulphide. In the second step the gas from the gasification reactor is rapidly cooled through direct contact with water, and with green liquor, which is formed when the molten droplets and the hydrogen sulphide are dissolved in the quench liquid. The cooled gas subsequently passes through a scrubber. In the lower section of the scrubber the gas is washed with circulating green liquor, and in the upper section of the scrubber the gas is washed with sodium hydroxide (or carbonate) solution and water for complete removal of any remaining sulfur bearing components in the gas. In the third step the now sulfur and particulate-free gas is used as a fuel for generating steam and, if it should be economically justified, also for production of electric power.

摘要： The wet method of combusting organic material dispersed in a liquid comprising waste liquor from wood pulping processes in which the organic material is oxidized by contact with air or other oxygenating gases at a temperature ranging between 180.degree. C. and 340.degree. C. and a correspondingly superatmospheric pressure. The combustion of oxygenation is carried out in two steps: namely, a first step in which the organic material is partially oxidized so that the major portion of the organic substances is converted into carbon dioxide and water, and a minor portion is converted to water-soluble low-molecular fatty acids resistant to oxidation; in a second oxidizing step, the residual oxygen-resistant fatty acids are combusted in the presence of a substantial excess of oxygen-enriched air or other molecular-oxygenating gas so as to liberate the total heat of combustion of the organic material and to impart to the resultant gaseous mixture of effluents a molecular oxygen content sufficient to achieve the partial oxidation in the first step.

摘要： High recovery of useful energy from the heat of reaction in the oxidation of black liquor is obtained by integrating the oxidation into the multiple effect evaporation system of the pulp mill recovery sequence. The heat of reaction is thereby recovered as flash steam, which when combined with the vapors from an appropriate evaporator body enables recovery of its energy through further evaporation. The oxidation reaction may be carried out on the liquor leaving the second effect of the evaporation sequence for maximum energy recovery, or in accordance with an alternative embodiment, the reaction is carried out between the first effect and the flash tank with preferable addition of a second flash tank in series with the first.

摘要： The liquid phase coking of waste kraft pulping liquors can be effected with a shorter residence time in the coking means at lower temperature, and lower pressure by reducing the pH of such liquors by at least one pH unit before coking. Products are lower in malodorous organic sulfur components than those produced at a higher pH.The lowering of the pH is achieved by adding sulfur dioxide to the liquor either as free SO.sub.2 or as an aqueous solution of SO.sub.2.

摘要： In the coking of spent ammonia and low pH sodium base sulfite wood pulping liquors in the liquid phase under pressure, gel-type coke formation is avoided by rapid heating to the coking temperature. Such rapid heating can be accomplished by the use of a metal bath having high heat transfer capacity, by using high pressure-high temperature steam injection or by means of a fluidized bed combustion system. The heating rate used is one of about 110* to about 150*F. per minute in the temperature interval of about 350* to about 550*F.

摘要： Embodiments of the present disclosure include a system, method, and apparatus comprising a direct steam generator configured to generate saturated steam or superheated steam and combustion exhaust constituents. A CONVAPORATOR™ Unit (CU) can be fluidly coupled to the direct steam generator. The CU can be configured to route the saturated steam or superheated steam and combustion exhaust constituents through a condenser portion of the CU via a condenser side steam conduit and can be configured to condense the super-heated steam or saturated steam to form a condensate. A separation tank and water return system can be fluidly coupled to a condenser side condensate conduit of the condenser portion of the CU. The separation tank and water return system can be configured to separate the combustion exhaust constituents from the condensate. An evaporator portion of the CU can be fluidly coupled with the separation tank and water return system via an evaporator side condensate conduit. The evaporator portion can be configured to evaporate the condensate from the separation tank and water return system via heat transfer between the condenser portion and evaporator portion to form steam. A turbine can be fluidly coupled with the evaporator portion of the CU via an evaporator side steam conduit.

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. CO.sub.2) 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 in which the liquid is introduced into the first end of a vortex while oxygen is introduced from exteriorly of the vortex 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 and removing the acidic gases from a center portion of the spiral path. A reactor for effecting the last mentioned specific procedure includes a pressurized vertical vessel having a downwardly extending stationary spiral surface mounted in the vessel substantially concentric with it. Surface manifestations may be provided on the spiral surface for enhancing mixing of liquid with surrounding gas.
