Development and scale-up of particle agglomeration processes for coal beneficiation

Understanding Water‐Based Bitumen Extraction from Athabasca Oil Sands

“…Another promising on-going research at the University of Alberta is to develop oily bubble flotation technique (Liu et al, 2002c;Wallwork et al, 2003). Oily bubbles have been tested in minerals and coal processing (Taggart, 1927;Shen and Wheelock, 2001;Liu et al, 2002c, solvent extraction (Chen et al, 2003), and de-inking processes (Gomez et al, 2001). In bitumen flotation, oily bubbles were generated by vaporizing the oil (kerosene) into the air addition stream.…”

Ilgın Linyit Kömürünün Yağ Aglomerasyonunun Ultrasonik Proses ile İyileştirilmesi

“…Köprüleme sıvısı olarak testlerde kullanılan atık Ayçiçek yağı okul mutfağından tedarik edildi ve atık yağın yoğunluğu 0,91 g/cm 3 olarak bulundu. Literatürde atık Ayçiçek yağlarının yoğunluğunun 0,9-0,92 g/cm 3 , viskozitesinin ise 14,9-145,2 mm 2 /s arasında değiştiği belirtilmektedir [37,38]. Öte [14,20,21,45].…”

Quality-By-Design (QbD): An Integrated Approach for Evaluation of Powder Blending Process Kinetics and Determination of Powder Blending End-point

“…When the batch size is increased, especially to the pilot scale and manufacturing scale, the size of the mixing vessel may play a significant role, as discussed previously. [27][28][29] On the other hand, powder segregation issue 25,30 associated with implementation and scale-up of the blending operation will lead to many challenges in achieving and maintaining blend uniformity for larger-scale blending vessels. In the latter case, first principles models or semiempirical scale-up models, in conjunction with computational tools such as computation flow dynamics (CFD) 31 and finite element method (FEM) 32 could be useful to gain a better understanding of the powder blending process behavior.…”
