Sintering of fume deposits in kraft recovery boilers

Creator:

Techakijkajorn, Udom

Abstract:

Fume, sub-micron aerosal particles in the combustion gases, have been identified as a cause of extensive plugging and fouling in the heat transfer section of a kraft recovery boiler in kraft pulp mills. After the deposition on the heat transfer surface, fume deposits will undergo the sintering process which causes...

Fluidized bed granulator for an autocausticization recovery process of sodium in black liquor : experiment and theory

Creator:

Thulstrup, Niels, 1970-

Abstract:

Production of dry particles made of titanium dioxide powder and black liquor is the first step in a newly proposed black liquor treatment process (Frederick et. al., 1992). This work investigates the granulation processes in a fluidized bed granulator of titanium dioxide and black liquor. Experiments are performed in a...

Kinetic and equilibrium analysis of metal ion adsorption onto bleached and unbleached kraft pulps

Creator:

Yantasee, Wassana

Abstract:

Most metal ions have negative impacts on pulp mill operations. The concentrations of metal ions on pulp fibers and in washwaters rise significantly with increased wastewater recycling. The development of technology to remove these metal ions requires an understanding of how metal ions are bound to pulp components. It is...
