Expert Course on Solvent Extraction
The Expert Course on Solvent Extraction aims at collecting information on solvent extraction spanning the full range from beginners to experts. The extraction basics are copied from the lecture 'Thermal Unit Operations' and indicated as such in the list below. The expert contributions are partly contained in a lecture on process intensification but also contain specialist discussions beyond any lecture actually given. It is the goal to include the specialist topics also on a lecture-like level, where special focus is directed towards explaining the theoretical background as well. The lectures are recorded on video and uploaded to YouTube in the playlist 'Expert Course on Solvent Extraction'. Continually further topics will be recorded and uploaded. Here the links to the individual manuscript chapters as well as to the corresponding videos are collected. Where a chapter subtitle is not associated to a video of pdf, the corresponding content is part of the previous pdf or video. Crossed out topics are planned already and will be uploaded in the near future. The numbers refer to the chapters and subchapters of the full manuscript. The order of the videos is that in which the course is practically presented, i.e. is arranged in a didactically feasible way. For the expert section they are arranged in a logical manner. The order of chapters in the manuscript is different, because it is intended as a reference mansucript, which follows a more systematic approach.
