Analysis of energy dissipation in stirred suspension polymerisation reactors using computational fluid dynamics
(WILEY-BLACKWELLHOBOKEN, 2012)
This work evaluates the spatial distribution of normalised rates of droplet breakage and droplet coalescence in liquidliquid dispersions maintained in agitated tanks at operation conditions normally used to perform suspension ...
Food Powder Properties
(Elsevier, 2017)
The food industry deals with a great amount of raw materials, ingredients and processed products, many of which are presented in powder form. Thus, much attention has been paid to the understanding of fundamental properties ...
Floculação: Considerações a partir da análise clássica e da avaliação direta da distribuição de tamanho de partículas
(2016-01-01)
This article presents some considerations on the flocculation from the classical analysis and direct evaluation of the particle size distribution. For this purpose, essays in bench scale were performed. The results were ...
Population Balance Discretization for Growth, Attrition, Aggregation, Breakage and Nucleation
(Elsevier, 2015-08-28)
This paper presents a new discretization method to solve the population balance equation (PBE) for batch and unsteady/steady-state continuous perfectly-mixed systems. The numerical technique is valid for any size change ...
Effect of raw material milling on ceramic proppants properties
(Elsevier Science, 2018-03)
Low density and high breakage resistance ceramic proppants were developed from kaolin, bauxite and monoaluminum phosphate (MAP). The effect of the particle size on the raw materials over the density, the open porosity and ...
Reversibility of al-kaolin and al-humic aggregates monitored by stable diameter and size distribution
(2018-07-01)
The reversibility of aggregates during flocculation was investigated. The stable diameter (d) and the power law slope coefficient of the particle size distribution (β) were applied to follow re-formation after breakage. A ...
Modeling of maize breakage in hammer mills of different scales through a population balance approach
(Elsevier Science Sa, 2020-09-20)
In this contribution a dynamic model ofmaize breakage in hammer mills of different scales is proposed through a population balance approach. The results of the pilot-scale experiments were used to fit the parameters of the ...
Preliminary study on low-density polystyrene microplastics bead removal from drinking water by coagulation-flocculation and sedimentation
(2021-12-01)
Microplastics (MPs), sized ~150 μm, have been found in tap water at levels of ~5 particles/L, suggesting that water treatment plants are not effectively removing MPs. Therefore, there is an urgent need to evaluate their ...
