Brownstock washing with a diffusion washer.  2, record 1, English, - diffusion%20washing

Record number: 1, Textual support number: 1 OBS

diffusion washer : A cylindrical screen located inside the top of an upflow tower which removes excess filtrate from the stock as it passes upwards between several thin concentric hollow rings that are perforated to permit the filtrate to enter. At the same time wash water is added to displace the filtrate and diffuse transversely through the stock.  3, record 1, English, - diffusion%20washing

diffuseur : Tamis cylindrique situé dans le haut d'une tour à courant ascendant qui élimine l'excès des filtrats de la pâte au fur et à mesure qu'elle passe verticalement entre des anneaux concentriques à plaques perforées pour permettre l'écoulement des filtrats. En même temps, on introduit de l'eau de lavage pour déplacer les filtrats en les diffusant radialement dans la pâte.  1, record 1, French, - lavage%20par%20diffusion

A representative medium-consistency system is shown in Figure 11-19. Pulp from a brown stock washer or decker at about 10-14% consistency is charged with caustic or oxidized white liquor. It is then preheated in a low-pressure steam mixer and pumped through one or more medium-consistency gas mixers to an upflow pressurized reaction tower. Steam and oxygen are added upstream of the medium-consistency mixer or are added directly into it. The reactor bottom may be hemispherical or conical, and the top is equipped with a discharger.... The stock is depressurized through a separator where steam is flashed and small amounts of by-product gases, oxygen and other noncondensibles are released.  1, record 5, English, - medium%2Dconsistency%20oxygen%20delignification
