Through detailed explanations, visual aids, and practical examples, this material covers the fundamental concepts of azeotropic and extractive distillation, including the flowsheet of azeotropic distillation columns, the role of entrainers, and the challenges posed by azeotropes in traditional distillation processes.   

This set contains 14 YouTube videos, created by Dr Niek Eisink and Dr Tjalling Canrinus of the Faculty of Science and Engineering of the University of Groningen. These instructional videos all deal with different laboratory techniques that are highly relevant for chemistry students and researchers, as well as others who work with chemical techniques in their day-to-day work. The following 14 topics are discussed in this set:

- Recrystallization
- Reflux setup
- Distillation
- Extraction
- Gloves
- Volumetric flasks
- Vacuum filtration
- UV-Vis spectrophotometer
- Thin Layer chromatography (TLC)
- Column chromatrography
- Schlenk line
- Greasing glass joints
- Micropipettes
- Rotary evaporator

The videos aim to be useful tools for current students and staff, professionals who are looking for a refresher on fundamental laboratory techniques, and other educators who want use these videos in their teaching and lab instruction.

Water supply is a problem of worldwide concern: more than 1 billion people do not have reliable access to clean drinking water. Water is a particular problem for the developing world, but scarcity also impacts industrial societies. Water purification and desalination technology can be used to convert brackish ground water or seawater into drinking water. The challenge is to do so sustainably, with minimum cost and energy consumption, and with appropriately accessible technologies.
This subject will survey the state-of-the-art in water purification by desalination and filtration. Fundamental thermodynamic and transport processes which govern the creation of fresh water from seawater and brackish ground water will be developed. The technologies of existing desalination systems will be discussed, and factors which limit the performance or the affordability of these systems will be highlighted. Energy efficiency will be a focus. Nanofiltration and emerging technologies for desalination will be considered. A student project in desalination will involve designing a well-water purification system for a village in Haiti.

Students learn about the techniques engineers have developed for changing ocean water into drinking water, including thermal and membrane desalination. They begin by reviewing the components of the natural water cycle. They see how filters, evaporation and/or condensation can be components of engineering desalination processes. They learn how processes can be viewed as systems, with unique objects, inputs, components and outputs, and sketch their own system diagrams to describe their own desalination plant designs.

This resource was created by Lisa Nichols (chemistry faculty at Butte Community College in Northern California) as a result of an academic sabbatical leave in the Fall-2015 to Spring 2016 term. The target audience are undergraduate students in organic chemistry.

In this resource you will find theory and procedures on the main organic lab techniques (chromatography, crystallization, extraction, distillation) as well as general concepts on how to set up and heat apparatuses (see the Table of Contents tab for a more complete listing of topics).

All procedures are accompanied by step-by-step pictures, and graphics are heavily utilized throughout the resource.

This course covers the general principles of separation by equilibrium and rate processes. Topics include staged cascades and applications to distillation, absorption, adsorption, and membrane processes. Phase equilibria and the role of diffusion are also covered.

"Multicomponent Distillation" is a comprehensive educational resource designed for chemical engineering students, aiming to equip them with the necessary skills and knowledge to effectively tackle complex multicomponent distillation problems. This unit comprises four lessons, each focusing on different methods and techniques essential for multicomponent separation. Beginning with fundamental principles of binary distillation, students progress to specialized methods such as Lewis-Matheson and Hengstebeck's methods, designed specifically for multicomponent systems.By the end of the unit, students emerge equipped with the skills and knowledge needed to confidently approach and solve a wide range of multicomponent distillation challenges in industrial settings.
