Lab Experiments

The Chair of Industrial Chemistry offers various experiments for compulsory and advanced practical courses within the framework of the courses of study in bioengineering, chemical engineering and chemistry.

In-depth Lab

Students interested in an in-depth lab will be involved in the current research of the department. Current proposed topics can be found here. Since the topics for student work can change very quickly, it is also recommended to ask the assistants directly.

Description

TC 2 ( = TC 30): Production of styrene from ethylbenzene

The subject of this experiment, which is supervised by the Chair of Industrial Chemistry (TC), is the production of styrene from ethylbenzene. Styrene is further processed in industry to polystyrene, a mass plastic known from everyday life. The experimental apparatus is a simplified model plant of the complete industrial process on a laboratory scale, a so-called "miniplant". It contains many components that give an impression of the professional practice of the chemical engineer.

TC 35: Wacker-Hoechst process

The homogeneously catalyzed oxidation of ethene to acetaldehyde is carried out in a two-stage process on a miniplant. The experimental plant is operated with an excess of oxygen (variant A) and a shortage of oxygen (variant B) in order to investigate how the regeneration of the catalyst solution affects the ethene conversion of the reaction.

TC 36: Metathesis of propene to ethene and butene

This lab experiment is a heterogeneously catalyzed reaction using propene metathesis as an example. First, a heterogeneous contact is prepared by impregnating an inorganic support (Al2O3) with the catalytically active metal salt (perrhenium acid). After subsequent activation by calcination to form the metal oxide, propene is catalytically converted.  By systematically varying the experimental conditions according to Box-Wilson's method, the optimum operating point of the plant is to be determined. The improvement in space-time yield compared with the starting point of the experiments is to be indicated.

TC 11: Chemical reactors: stirred tank reactors

A prerequisite for the manufacture of a chemical product is first of all a chemical reaction of the starting materials in a chemical reactor. In order to be able to design and operate this reactor optimally, knowledge of the behavior of chemical reactors is indispensable. Almost every chemical reactor can be traced back to the basic types (or combinations thereof) presented in the practical experiments TC11 and TC 14. The aim of the practical course is to introduce the behavior of the basic types of chemical reactors on the basis of a model reaction for a stirred tank reactor, which is operated discontinuously and continuously.

TC 14: Chemical reactors: flow tube

A prerequisite for the manufacture of a chemical product is first of all a chemical reaction of the starting materials in a chemical reactor. In order to be able to design and operate this reactor optimally, knowledge of the behavior of chemical reactors is indispensable. Almost every chemical reactor can be traced back to the basic types (or combinations thereof) presented in these practical experiments. The aim of the practical experiment is an introduction to the behavior of the basic types of chemical reactors using a model reaction for a tubular reactor.

TC 4 ( = TC 31): liquid-liquid-extraction

The first goal of this experiment is to learn about the representation of ternary mixtures in triangular coordinates and the graphical possibilities for performing balances in such a diagram. Some examples will be used to measure equilibrium data. Then, a four-stage countercurrent extraction is first designed by a graphical stage construction and then the procedure is reproduced in a laboratory apparatus with the operating data obtained in the process. The values obtained theoretically and those obtained in practical operation are compared and the efficiency of the laboratory apparatus is determined.

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”.
