Modeling and Simulation of a lab-scale Fluidised Bed [PDF]

Modeling, Identification and Control, 2002
The flow behaviour of a lab-scale fluidised bed with a central jet has been simulated. The study has been performed with an in-house computational fluid dynamics (CFD) model named FLOTRACS-MP-3D.

Techno-Economic Evaluation of Biological and Fluidised-Bed Based Methanation Process Chains for Grid-Ready Biomethane Production

Frontiers in Energy Research, 2022
Three different power-to-methane process chains with grid injection in two scales (1 MWel and 6 MWel) were analysed regarding their investment and operation cost. The process chains were based on biological or catalytic bubbling fluidised bed methanation

Enrichment of Limestone Used in the Desulphurisation of Fluidised-Bed-Boiler Flue Gases

Adsorption Science & Technology, 2021
In this work, we analysed the impact of adding several previously untested Sorbacal calcium-based substances to the raw limestone that is currently used for dry desulphurisation of brown-coal fluidised-bed boilers.

Liquid injection in a fluidised bed: Temperature uniformity

Chemical Engineering Science, 2022
Liquid injection in fluidized beds occurs in well-established industrial processes as fluid coking, spray fluidzed bed granulation and condensed mode gas-phase polymerisation. These processes still suffer performance issues due to their complex nature, where liquid injection adds even more complexity. In this work, the effect of liquid injection on the

CFD-DEM Analysis of Particle Attrition in a Jet in a Fluidised Bed

EPJ Web of Conferences, 2017
In fluidised bed processes, the solids are in vigorous motion and thus inevitably subjected to mechanical stresses due to inter-particle and particle-wall impacts.

Effect of fluidised bed drying on ginsenoside content in hairy root cultures of Panax ginseng C.A. Meyer

Indonesian Journal of Biotechnology, 2023
Korean Ginseng (Panax ginseng C.A. Meyer) is a high‐value herb with many pharmacological benefits due to its primary active compound, ginsenosides. The most ginsenosides are known to be thermolabile and susceptible to degradation at high‐temperature ...
