Abstract :
[en] 1. Introduction To support students studying Chemical Engineering, the ordinary lectures had originally been recorded on video. This was very much appreciated by the students. Of course preparing the recording and also the final cutting of the videos every year was quite some effort. At the same time, it was realized that the quality was limited, if the standard situation in a classroom was recorded. Finally, it occurred that within the group many elaborate presentations had been prepared over the years, including dedicated workshops for industry. This apparently was fleeting effort. Thus it was realized that preparing dedicated presentation in the best possible quality and supplying them on YouTube would be a similar effort as previously, enhance the video quality significantly, and would ensure that all knowledge collected over the years in the group could be delivered to everybody interested. 2. Realization As a start a variety of configurations for recording videos have been tried out. The ordinary lecture configurations lead to either the presenting person being only dimly lit or the picture of the projector being too bright, so that details of the diagrams are lost. Thus especially different lighting setups have been tested. Optimal quality can be reached by using a large TV screen for projecting the presentation slides and to use a notebook/tablet with a suitable writing program for the derivations. This is shown exemplarily in Figure 1. This way a direct interaction between presenter and presentation is possible and derivations can easily be recorded. With this setup a series of videos is currently being recorded, which starts out with the basics of thermal unit operations, which will also include extraction, phase separation, etc. In the meantime already the basic design principles have been made available on YouTube, e.g. including a generalized McCabe-Thiele method. This is an ongoing project, where the presentations will finally also cover all expertise acquired in the group, e.g. on extractant selection, coalescence and phase separation, design of reactive steps. This is supported by supplying the lecture manuscript as PDF file on our website. This way a collection of easily accessible and complete teaching and advanced-training material is made available. 3. Invitation Since in a university environment large-scale equipment together with e.g. trouble-shooting issues cannot be addressed, the author invites other experts in the field to contribute. Also it turns out that it is significant effort to obtain photos of large-scale equipment. While all companies addressed so far were quite supportive, nevertheless for each individual photo or diagram the copyright issues need to be addressed. Here also support from companies with respect to real-world photos and/or videos would be welcome. Of course appropriate credits will be given. Since also problematic cases with e.g. corroded examples would be welcome, confidential treatment of the source can be ensured as well.
