Simulation of washing of packed bed of porous particles using quintic Hermite splines
Autor: Shelly Arora, František Potůček, Inderpreet Kaur
Publikováno v: Journal of King Saud University: Engineering Sciences, Vol 31, Iss 2, Pp 114-121 (2019)
A comprehensive two phase non-linear mathematical model has been presented with special reference to particle geometry and pore radius of particles. Model equations have been divided into bulk fluid phase and particle phase. Bulk fluid phase is chara

Study of Two-Phase Nonlinear Advection Dispersion Model for Displacement Washing of Porous Particles Using OCFE with Lagrangian Basis
Autor: Dereje Alemu Alemar, František Potůček, Shelly Arora
Publikováno v: Arabian Journal for Science and Engineering. 45:531-542
A comprehensive diffusion dispersion model has been presented for displacement washing of porous particles. Model equations have been divided into two phases, namely bulk fluid phase and particle phase. Both the phases have been characterized by part

NUMBER OF IDEAL STAGES AS AN EFFICIENCY PARAMETER FOR DISPLACEMENT WASHING OF PULP
Autor: František Potůček
Publikováno v: Cellulose Chemistry and Technology. 53:333-340
In this paper, the concept of the number of ideal stages of dilution and thickening commonly used for the description of counter-current washing systems was applied to quantify the efficiency of displacement washing of pulp. Two kraft pulps cooked fr

Účinnost vrstvy a objemový koeficient převodu hmoty jako parametry přenosu hmoty při vytěsňovacím praní buničiny
Autor: František Potůček
The long-fibred spruce sulphite and kraft pulps, as well as short-fibred soda pulp cooked from rapeseed straw were subjected to displacement washing under laboratory conditions. Pure water was used as wash liquid, the conductivity of which was descri

Displacement washing of soda rapeseed pulp
Autor: František Potůček, Kateřina Hájková
Publikováno v: Chemical Papers. 69
The paper deals with the displacement washing of unbleached pulp cooked from rapeseed straw by soda pulping under laboratory conditions. Pulp fibres were characterised by their average length, as well as by effective specific volume and surface. Usin

Washing of Pulp Fibre Bed
Autor: František Potůček
Publikováno v: Collection of Czechoslovak Chemical Communications. 62:626-644
The mechanism of the displacement washing of unbleached kraft pulp was investigated. The flow of the wash liquid through a pulp bed was described by the dispersion model using one dimensionless parameter known as the Peclet number. To characterize th

Displacement washing of kraft pulp cooked from a blend of hardwoods
Autor: František Potůček, Jozef Miklík
Publikováno v: Chemical Papers. 64
The aim of this work was to investigate the displacement washing of kraft pulp manufactured from a blend of hardwoods. The experiments were carried out in a laboratory washing cell. In order to characterise the pulp fibres, the degree of freeness, ka
