- High-Speed Camera-Based Analysis of the Lithium Ceramic Pebble Fabrication Process
Patrick Waibel, Jörg Matthes, Oliver Leys, Matthias Kolb, Hubert B. Keller and Regina Knitter
Article first published online: 10 SEP 2014 | DOI: 10.1002/ceat.201300769
Regarding the melt-based fabrication of lithium ceramic pebbles, a high-speed camera-based method enabling the analysis of the melt jet and the droplets directly in their formation phase is presented. The image-based extraction of individual droplet properties such as dynamic changes or agglomerations provided deeper insights into the melt-based fabrication process.

In recent years, coal oxidation under mild conditions in terms of relatively low temperatures and normal pressure has drawn increasing attention. A critical review on different methods of coal oxidation may advance the understanding of the oxidation mechanisms and identify existing issues of applying such techniques in both comprehending the coal molecular structure and production of organic chemicals.
- Effects of Contamination and Power-Law Fluid Viscosity on Heat Transfer Phenomena of Spherical Bubbles
Venkata Swamy Nalajala and Nanda Kishore
Article first published online: 9 SEP 2014 | DOI: 10.1002/ceat.201400004
When a contaminated continuous liquid obeys the power-law of non-Newtonian behavior, to date analogous information is not available. Heat transfer phenomena of partially contaminated spherical bubbles are numerically investigated applying the stagnant spherical cap model over wide ranges of pertinent conditions by solving the governing conservation equations of mass, momentum, and energy via a segregated approach.
- Integration of Aqueous Two-Phase Extraction into Downstream Processing
Jan Eggersgluess, Tim Wellsandt and Jochen Strube
Article first published online: 9 SEP 2014 | DOI: 10.1002/ceat.201400114
Successful integration into downstream processing requires a reliable prediction of the process performance in an early development stage. Aqueous-two-phase extraction (ATPE) modeling studies and comparison with experimental data for a mini-plant extraction column are provided. Economic evaluation between ATPE and Protein A chromatography indicates cost-saving factors of up to five-fold for ATPE.
- CFD Modeling of a Carbonation Reactor with a K-Based Dry Sorbent for CO2 Capture
Guangbin Yu, Bing Dai, Juhui Chen, Di Liu, Xiaoyang Yu, Junpeng Shao and Lei Zhao

CO2 removal from flue gas with regenerable dry solid sorbents is a promising possibility to capture CO2. Such process in a carbonation reactor is investigated with a K-based dry sorbent by CFD simulation. A multiscale drag coefficient model is integrated into the two-fluid model to describe the cluster effects. Reactor height and operating pressure have a great impact on CO2 removal.
