Les grandes modifications apportées par le passage en supercritique sont dues essentiellement à l'augmentation de la pression et de la température de la vapeur surchauffée. Elles consistent principalement en : la disparition de la vaporisation. Ceci implique une modification de la chaudière, qui ne contient plus de ballon. Ici le fluide de travail passe de l'état liquide à l'état gazeux à pression constante sans changement de phase dans les tubes tapissant la paroi de la chaudière. Il n'y a donc plus un point de pincement unique mais une zone de pincement.  2, record 8, French, - point%20de%20pincement

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 10, English, - medium%2Dconsistency%20oxygen%20delignification
