Physical Unit Operations 1

161104 anpf physical unit operations 1-1The lecture 'Thermal Unit Operations', which are part of the ULg lecture 'Physical Unit Operations 1', is being recorded on video and uploaded to YouTube in the playlist 'Thermal Unit Operations'. 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. Not all chapters are contained in this video series, because some chapters are left for an expert course while others are relevant only for introductory lectures of non chemical engineering students. The order of the videos is that in which the course is practically presented, i.e. is arranged in a didactically feasible way. The order of chapters in the manuscript is different, because it is intended as a reference mansucript, which follows a more systematic approach.


Since the course is intended as university course, where it is expected that the students will be able to freely transfer the knowledge to other cases, the listener should expect sufficiently detailed derivations of the methods presented.


Some videos have meanwhile been synchronized in Portuguese (Brazilian). You find the playlist here.
