    摘要： Method of recovering energy from waste liquors from pulp processes, wherein the waste liquor is burned in a waste liquor recovery boiler (18) and energy is recovered from the flue gases by producing saturated or partially superheated steam in the recovery boiler. According to the invention, a portion of the waste liquor is gasified in a gasifying reactor (16) in order to produce combustion gas. The combustion gas is burned in a separate superheating boiler, in which the steam produced in the recovery boiler is superheated.

    摘要： The present invention relates to a process for the extraction of chemicals and energy from cellulose spent liquors, preferably black liquor obtained in the sulphate cellulose process, wherein the spent liquor is introduced into a gasification reactor (1) for pyrolysis and partial incineration, wherein an energy-rich gas is formed containing particles of inorganic chemical melt, the said gas mixture is conveyed out of the reactor (1) and concomitantly cooled by injection of a finely-divided cooling medium, preferably water, in connection with the departure from the reactor (1), the said mixture of gas and non-adhesive chemical particles is led from a cooling chamber (2) arranged in connection with the gasification reactor (1) to a separating arrangement (3), preferably a cyclone, where the non-adhesive chemical particles are separated from the gas, the gas stream, essentially cleaned of chemical particles, is taken out via an upper connection on the separating arrangement (3) while the chemical particles are taken out via a lower connection on the separating arrangement (3), wherein the melt particles leaving the reactor in the gas mixture are cooled to a temperature where they have at least partially solidified and been converted to solid phase, so that the particles included in the gas mixture are non-adhesive, and that a subsequent heat exchange of the separated gas is carried out from an essentially preserved temperature level.

    摘要： The present invention relates to a process for partial combustion of cellulose spent liquors using a burner equipped with a liquor lance and an atomizing nozzle, which burner is connected to a reactor operating at pressures in the range of 1.1 to 150 bars while supplying an oxygen containing gas, whereby the weight ratio between the oxygen containing gas supplied through the burner and the spent liquor solids supplied through the burner is less than 2:1, and that at least half of the non-fuel bound oxygen required for the partial combustion is discharged into the reactor through the atomizing nozzle.

    摘要： Méthode d'élaboration de liqueur de digestion à haute sulfidité à partir d'une liqueur épuisée issue de la digestion d'une fibre cellulosique, de préférence sans passer par l'étape classique de caustification. La méthode consiste à décomposer thermiquement la liqueur épuisée en conditions de réduction dans un réacteur à une pression comprise entre la pression atmosphérique et environ 150 bars et à une température allant d'environ 500 à 1600 °C, de manière à obtenir dans le réacteur une phase gazeuse combustible renfermant de l'acide hydrosulfurique, qui est ensuite extraite du réacteur, et une matière en phase solide ou fondue renfermant essentiellement du sulfure de sodium, que l'on dissout dans une solution aqueuse pour obtenir ladite liqueur de digestion. Selon ce procédé, l'acide hydrosulfurique est récupéré de la phase gazeuse puis retourné dans le réacteur pour être présent au cours de la décomposition thermique de la liqueur épuisée.

    摘要： The present invention relates to a process for partial combustion of cellulose spent liquors using a burner connected to a reactor while adding an oxygen containing gas, maintaining a temperature of more than 700°C within the reactor and that at least half of the non-fuel related amount of oxygen which shall be added to the reactor to partially combust the cellulose spent liquor added through the burner, is added to the reactor as a hot oxygen containing gas added through a channel arranged coaxially around a liquor lance provided for the addition of said cellulose spent liquor, whereby the weight ratio between the oxygen of the oxygen containing gas and the cellulose spent liquor solids is in the range of 0.1-0.7:1.
