摘要： A wood pulping process includes producing weak black liquor and cooling the liquor as well as recovering heat therefrom by directing the weak black liquor through a spray film evaporator. A feed or condensate is directed into the spray film evaporator and the feed or condensate is sprayed onto the outer surfaces of a bundle of tubes. This results in the feed or the condensate being vaporized and producing a vapor that can be utilized as a heat source for other processes in a pulp mill.

In the process, the gas is counter-currently brought into multistage contact, preferably comprising three stages (6, 7, 8), with circulating carbonate-containing alkaline solutions, preferably sodium carbonate solutions (25), the pH of which is adjusted during the absorption to about 9-12 by the addition of a hydroxide, preferably a sodium hydroxide solution (26, 27, 28).

The apparatus comprises a container (1) having a gas inlet (2), a gas outlet (4), and a packing (9) arranged in several successive stages (6, 7, 8). The apparatus has means (25) for supplying a carbonate-containing solution to the last stage and through this stage countercurrently to the gas, and for recycling the solution across this stage; conduits (29, 30) arranged between the stages for supplying a partial flow of the solution from one stage to a preceding stage; means (26, 27, 28) for supplying a hydroxide to the carbonate-containing solution in at least one of the stages (6, 7, 8); and an outlet conduit (31) from the first stage, as seen in the feed direction of the gas, for discharging a sulphide-containing liquid.

摘要： Steam (preferably clean steam) having less noncondensible gases than steam produced by conventional black liquor flashing is produced from hot black liquor from a digester of a pulp mill. A heat exchanger is utilized and the hot black liquor is passed through the heat exchanger in heat exchange contact with an evaporable liquid, preferably clean water. After the water is heated in the heat exchanger it is flashed in at least one flash tank where the heat exchanger is a liquid-to-liquid heat exchanger. The heat exchanger may alternatively include an evaporator (such as a falling film evaporator) in which case the black liquor is passed through an inductor before it enters the evaporator. Alternatively, the heat exchanger may be one or more boilers, such as kettle boilers, in which case the black liquor preferably passes through a cooler after the boilers. Heat energy and turpentine recovery are also maximized.

摘要： A process for the comminution, in particular defibrillation, and reaction of fibrous materials having a high dry solids content with the addition of a circulating medium, preferably a carrier gas and/or reaction agent, as well as optionally of chemicals. The invention is mainly characterized in that the circulating medium is recycled after leaving the comminuting device, by changing its temperature, and is then recycled to the comminuting device. Another embodiment of the invention is characterized in that the fibrous materials and liquid reaction agent are separated from the carrier gas and reaction agent vapors, which are then recycled back to comminuting device. A plant for carrying out this process is mainly characterized in that the comminuting device and route for recycling and treatment of the circulating medium form a closed system.
