Desired learning outcomes

Upon successful completion of this module, students should be able to:

  • Recognize the differences between the production of substances in the laboratory and on an industrial scale and consider them for application
  • Apply the fundamentals of thermodynamics, phase equilibria, reaction kinetics, mass and heat transport, and mass and heat balancing to explain the operating principles of the major chemical reactors and separation processes
  • Discuss the possible applications of the various basic types of chemical reactors
  • Explain the action of heterogeneous and homogeneous catalysts and the reaction processes involved
  • Carry out stage designs taking into account phase equilibria and mass balances as a basis for the design of separation processes
  • Understand the design and function of essential equipment in chemical plants and describe their advantages and disadvantages for specific applications
  • Describe a chemical process with the aid of a process flow diagram
  • Explain the production of essential inorganic and organic precursors, intermediates and final products of the chemical industry using process flow diagrams
  • Describe the processes carried out in the practical experiments including their industrial significance
  • Explain the essential chemical / physico-chemical theoretical principles of the experiments
  • Present the measurements carried out and their evaluation
  • Discuss the large-scale designs and applications of the reaction and separation apparatus discussed in the practical course experiments

Key competencies taught

Essential skills for a successful career in the chemical industry are taught:

Methodological skills

  • The ability to evaluate a chemical process not only from a chemical point of view but also from an engineering, equipment, economic and ecological point of view
  • The combination of theoretical knowledge with practical experience from the internship

Social skills

  • Learning about engineering issues improves the ability to work in a team with graduates of chemical engineering and other disciplines
  • The execution and evaluation of the internship experiments in groups of three students promotes the ability to work in teams

Location & approach

The campus of TU Dort­mund University is located close to interstate junction Dort­mund West, where the Sauerlandlinie A 45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dort­mund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dort­mund-Dorstfeld” (closer to North Campus). Signs for the uni­ver­si­ty are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dort­mund.

To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.

TU Dort­mund University has its own train station (“Dort­mund Uni­ver­si­tät”). From there, suburban trains (S-Bahn) leave for Dort­mund main station (“Dort­mund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The uni­ver­si­ty is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.

You can also take the bus or subway train from Dort­mund city to the uni­ver­si­ty: From Dort­mund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dort­mund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dort­mund main station to the stop “Dort­mund Kampstraße”. From there, take U43 or U44 to the stop “Dort­mund Wittener Straße”. Switch to bus line 447 and get off at “Dort­mund Uni­ver­si­tät S”.

The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.

The H-Bahn is one of the hallmarks of TU Dort­mund University. There are two stations on North Campus. One (“Dort­mund Uni­ver­si­tät S”) is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
