Integration of a cogeneration unit into a kraft pulping process
Applied Thermal Engineering, 2010The integration of cogeneration with other measures that impact the power production capacity in a Canadian Kraft pulping mill is studied. Those measures are removal of pressure reduction valves, adjustment of the steam pressure level, biomass boiler capacity, and reduction in process energy demand.

Journal of Agricultural and Food Chemistry, 2022
This paper presents comments on the recently published article by Lahtinen et al., showing results about study the chemical structure of insoluble residual lignin, the presence of fatty acids in kraft lignin, and the origin of the secoisolariciresinol fragment. The analytical procedures used in the study seem to be reliable. However, in my opinion, the

Kinetic Model for Kraft Pulping Process
Industrial & Engineering Chemistry Research, 2005A new mechanism is proposed for the heterogeneous delignification reaction during the Kraft pulping process. The mechanism consists of three key kinetic steps:  (1) adsorption of hydroxide and hydrosulfide ions on lignin; (2) surface reaction on the solid surface to produce degraded lignin products; and (3) desorption of degradation products from the ...

Hindrance to nanofibrillation of undried pulp produced by the kraft cooking process
Carbohydrate Polymers, 2022Kraft pulp is the most common and economically advantageous raw material for making cellulose nanofibers (CNFs). However, when kraft pulp is subjected to mechanical fibrillation, unfibrillated pulp always remains, even though the pulp is undried. In this study, the effect of the kraft pulping process on the fibrillation of undried pulp was studied. The
