Abstract: There is provided a method of providing a ranked list of computer-implemented activities to a user. As a performed activity is received, a plurality of lists, which each of the lists defines a ranking of activities, is accessed. The rankings of different lists are calculated with respect to different time horizons. The positions in the lists are associated with scores which are updated in view of the received activity. Also, the rankings of the lists are updated in view of the received activity. The lists are then combined into a single list. The combination is based on the updated lists and the scores associated with the positions in the lists.

Abstract: The arrangement is for positioning equipment in association with an opening in a boiler wall and has a rotation mechanism that rotates the equipment around a virtual rotation axis that lies within the outer wall of the boiler. During the use of a liquor spreader for the introduction of combustible material, the opening of the liquor spreader is arranged in the virtual center of rotation so that the point at which the combustible material is introduced is retained independently of the angle of rotation. The liquor spreader is united either with a glide device or the guide in the rotation mechanism.

Abstract: Process for the recovery of chemicals and energy from spent liquor obtained in the chemical pulping process, in which the spent liquor is gasified under sub-stoichiometric conditions to produce partly one phase of solid and/or fused material, together with partly one phase of a flammable gaseous material, whereafter the said phases are cooled by direct contact with a cooling medium (9), is separated from the said phase of flammable gaseous material in order to be dissolved and collected up as a product liquid in a product liquid receiver (11). According to the invention, the said cooling medium (9) consists of an essentially water-free cooling medium, which after vaporizing/cracking increases the calorific value of the flammable gaseous material drawn off. At the same time, the process is improved in this way since the flammable gases can be used more effectively for the purpose of e.g. generating energy.

Abstract: A method and apparatus for drying material, especially wood particles, having moisture therein, comprising depositing the material to a selected depth onto a transport conveyor at the first end of a drying chamber. Heat is applied to the material as it is transported toward the opposite second end of the drying chamber so that, adjacent the second end, the material forms essentially two layers, a first layer having a first level of moisture therein and a second layer having a second level of moisture therein which is different from the moisture content of the first layer. Means are provided adjacent the second end for removing the second layer, which has the desired moisture, from the conveyor and directing that layer exteriorly of the chamber. The first layer, which has a remaining moisture content greater than the first layer, may be further dried to achieve the desired moisture content.

Abstract: Process for recovering chemicals and energy from black liquor, where the black liquor is gasified with CO, CO.sub.2, CH.sub.4, H.sub.2, and H.sub.2 S, in gaseous form, and Na.sub.2 CO.sub.3, NaOH and Na.sub.2 S, in the form of drops of smelt, being principally formed. The mixture of gas and smelt is cooled, in a first stage, by direct contact with a cooling liquid, whereupon a part of the cooling liquid is volatilized, and the smelt drops are separated off and dissolved in the remaining part of the cooling liquid with the formation of a liquid bath of green liquor. In a second stage, the gas is washed and saturated with moisture by direct contact with a washing liquid bath. After the gas has been washed in the second stage, energy in the form of thermal energy and condensation heat is recovered from the gas in an indirect condenser.

Abstract: Provided is a quench vessel containing at least two separate internal vessels. A receiving liquor is contained in the first internal vessel and a washing liquid bath is contained in a second internal vessel.

The spent liquor is gasified in at least two reactors, a first and a second stream of solid and/or smelt material and of combustible gaseous material being formed. The formed material is treated in one or more devices (5, 6, 7, 8), whereby a first (9) and a second liquor (27) are formed. The pressure and/or temperature in the first reactor differ(s) from the pressure and/or temperature in the second reactor. In addition, one or more process chemicals are recovered selectively from the formed liquor and/or gas, and are thereafter returned in whole or in part to one or more of the reactors (1, 2) and/or to one or more of the devices (5, 6, 7, 8) for treatment of the formed material.
