摘要： The invention relates to an improved two vessel cooking system, wherein the first vessel is an atmospheric impregnation vessel and the second vessel is a pressurized digester, where hot black liquor is finally flashed off inside the impregnation vessel for steaming the cellulosic material and providing the impregnation liquor. According to the inventive method is an additional cleaner wash liquor heated and added to final cook zone in digester, while displacing a corresponding amount of hot black liquor before the final cook zone, and the heat value in the hot black liquor is recovered first in transport circulation before being used as source for flashing off steam used to steam the comminuted cellulosic material inside the impregnation liquor and final use as impregnation liquor. The invention results in a cooking process with high yield and improved delignification in final cooking phases and reduced COD content in the produced pulp without increasing steam consumption.

摘要： In a method of processing cellulose pulp, which is produced by digesting from softwood or hardwood chips in a digester (1), the digested pulp is washed, the washed pulp is processed in an oxygen stage, and the pulp is further washed and bleached in a bleaching plant. Soap and gas and/or other light materials produced in the digesting process are separated from a filtrate and/or from black liquor by means of a pressurized separation apparatus (16, 22, 48, 49, 52) such as a hydrocyclone, a centrifuge or a pump.

摘要： The method is for separation of lignin from original black liquor (BLIN) that has a first precipitation phase (PR1/PR2) for precipitation of lignin by a first acidification using acidifier, CO2, at alkaline conditions, then separating a lignin cake with subsequent suspension of the lignin cake in a strong acid in order to leach out metals from the lignin followed by dewatering and obtaining a clean lignin product LP. Lignin germ particles (LG) are added to the original black liquor in the first precipitation stage, preferably between two phases in said precipitation stage, in order to increase lignin particle growth on such lignin germ particles instead of spontaneous nucleation of lignin particles in said original black liquor. This results in improved filterability in subsequent dewatering and lignin cake formation and hence an increased lignin yield.

摘要： The invention concerns a analytical method for measuring the soap content in black liquor. The analytical method comprises a first step where a defined amount of black liquor is arranged in analytical container, a second step where the black liquor is centrifuged and a soap concentrate is gathered in the upper part of the analytical container, a third step where the amount of soap concentrate is determined, and a fourth step where the soap content is calculated. By centrifuging the black liquor soap concentrated with a soap content of 58- 62% is obtained, which enable measurement of the dry matter with an accuracy of ± 2% within a very short time period. In one embodiment the analytical method comprises a fifth step where a modification of the calculated soap content is made with consideration to the density of the black liquor. In another embodiment of the invention the cylindrically symmetrical analytical container comprises a neck 2 with scale marks and a lower part 1. The defined amount of black liquor is defined by filling the analytical container to the uppermost mark, while the amount of soap concentrate is determined by the lower boundary of the soap concentrate, which can be measured with the scale marks. The invention also comprises an analytical container for us with such a method.

摘要： When processing cellulosic biomass, it may be desirable for a digestion unit to operate without being fully depressurized for process efficiency purposes. A biomass conversion system can comprise a first digestion unit and a second digestion unit that are operatively connected to one another; a valve separating the first digestion unit from the second digestion unit; a fluid circulation loop establishing fluid communication between an outlet of the first digestion unit and an inlet of the second digestion unit; and a bypass line establishing fluid communication between an outlet of the second digestion unit and the fluid circulation loop.
