Information

Ziele, Inhalte und Methode der Lehrveranstaltung

More energy efficient methods for the purification of chemicals may save many millions of tonnes of CO2 emissions annually and enable new sources of materials to be exploited
Unfortunately, alternatives to distillation, such as separating molecules according to their chemical properties or size, remain underdeveloped and/or expensive to scale. Engineers need to
develop better separation techniques that do not rely heavily on heat.
This course highlights seven chemical separation processes that, if improved, would reap great global benefits. We will learn why each separation is important, how the separation is performed currently, and together we will look to the future for solutions!

The 7 separations are:
1. Hydrocarbons from crude oil
2. Uranium from seawater
3. Alkenes from alkanes
4. Greenhouse gases from emissions
5. Rare-earth metals from ores
6. Benzene derivatives from each other
7. Trace contaminants from water

Art der Leistungskontrolle und erlaubte Hilfsmittel

Oral examination with individual appointment - up to 2 students at a time. Typically 30-60 minutes. In the case of Covid-19 restrictions exams will be conducted online.

Mindestanforderungen und Beurteilungsmaßstab

At least three questions per student. For a pass grade more than half of the questions should be answered correctly.

Prüfungsstoff

Lecture content:

Importance of separations. Importance of isolated chemicals. Why are improvements required? Conventional separation techniques. Drawbacks. Future outlook.

Literatur

Lecture slides primarily.

"David S. Sholl & Ryan P. Lively, Nature, 2016, 532, 435–437" was the inspiration for the course and also a rich source for further reading.
