In this study, extremum seeking is used to assess the actual critical substrate level, which is a function of the cell respiratory capacity. The latter is modelled as a function representing the existence of two different metabolic modes, namely the respirative mode and the respiro-fermentative mode, as well as modulation factors taking account of ...

A dynamic simulation model of the pilot paper machine was developed from first-principles. To describe the wet-end chemistry effect, the first-pass retention was included in the model as a new independent variable. The important factors affecting the dynamics of the wet-end are first-pass retention and the parameters related to the white water circulation.Dans un effort pour développer des stratégies de contrôle robustes pour la partie humide de la fabrication du papier, on a mené un programme expérimental pour modéliser le comportement dynamique de la rétention d'agents de remplissage dans le papier à l'aide d'une machine à papier pilote Fourdrinier et d'un système d'aide à la rétention cationique poly(acrylamide)/bentonite. Un modèle de simulation dynamique du pilote a été mis au point à partir des principes fondamentaux. Pour décrire l'effet de la chimie de la partie humide, la rétention lors du premier passage a été incluse dans le modèle comme nouvelle variable indépendante. Les facteurs importants qui affectent la dynamique de la partie humide sont la rétention lors du premier passage et les paramètres reliés à la circulation des eaux blanches.

It is rich in sugars and contains dissolved organic matters. The purpose of this study is to investigate the optimization of lignin recovery from wood pre-hydrolysates and to characterize the extracted lignin. The optimal conditions for lignin extraction have been determined to be (a) a filtration temperature of 40 °C, (b) a sulfuric acid concentration of 8.5 kg·m−3, and (c) a coagulation time of 180 min. Using these conditions, high filtration rates have been obtained and the extracted lignin has a low content of impurities (8.3%), a low molecular weight (1270 Da), and a very low polydispersity (Mw/Mn = 1.22). Compared to kraft lignin, the pre-hydrolysate lignin has a much lower molecular weight and could be a potential candidate for niche applications. A high lignin recovery rate is possible (52% of the total lignin content in the pre-hydrolysate).
