Oxidation process concept to produce lignin dispersants at a kraft pulp mill
Nordic Pulp & Paper Research Journal, 2022 This paper presents the concept of an alkali-O2 oxidation process for producing lignin dispersants in a feasible manner at a kraft pulp mill. The oxidation process uses O2 gas to increase the anionic charge of lignin and the final oxidised lignin can ...

Effect of dispersant on the performances of an ice slurry-wet precooling system
Case Studies in Thermal Engineering, 2023 This study addresses the problem of prolonged precooling time and excessive weight loss of fruits and vegetables during postharvest processes. Ice slurry precooling system shows potential but faces challenges like low undercooling and ice blockage ...

Asphaltene Precipitation and the Influence of Dispersants and Inhibitors on Morphology Probed by AFM
Colloids and Interfaces, 2023 Bridging the gap between laboratory-scale experiments and actual oilfield operations is a complex task that requires a compromise between real (authentic) fluids and model systems.

Synthesis of Lignosulfonate-Based Dispersants for Application in Concrete Formulations
Materials, 2021 Lignosulfonates (LS) are products from the sulfite pulping process that could be applied as renewable environmentally-friendly polymeric surfactants. Being widely used as plasticizers and water-reducing admixtures in concrete formulations LS compete in ...

SSRN Electronic Journal, 2003 We model firm pricing given consumers follow simple reservation price rules. Such reservation rules are rational when consumers are sufficiently impatient. The equilibrium exhibits price dispersion in pure strategies, with lower price firms earning higher profits.

Dispersive Estimates for Full Dispersion KP Equations [PDF]
Journal of Mathematical Fluid Mechanics, 2021 AbstractWe prove several dispersive estimates for the linear part of the Full Dispersion Kadomtsev–Petviashvili introduced by David Lannes to overcome some shortcomings of the classical Kadomtsev–Petviashvili equations. The proof of these estimates combines the stationary phase method with sharp asymptotics on asymmetric Bessel functions, which may be ...
