Henrik Bettin - APT - TU Dortmund

Location & approach

By Car

The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.

By bus and train

The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 15 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr Transport Association, and DSW21 also offer an interactive route network map.

The H-Bahn

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.

By Airplane

From Dortmund Airport, the AirportExpress takes just over 20 minutes to Dortmund's main train station, and from there, the S-Bahn takes you to the university. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.

Since 2024	PhD at the Laboratory of Plant and Process Design, TU Dortmund University Field of Research: "Development of an Archimedes Tube Crystallizer for small-scale continuous cooling crystallization"

Field of Research

Although batch crystallization remains the standard approach in industrial crystallization, the use of continuous crystallizers is promising in terms of investment and operating costs, process control and flexibility for chemicals and APIs with low production volumes.

One promising concept for continuous crystallizers is the Archimedes Tube Crystallizer (ATC). Small discrete liquid segments are transported through the ATC based on the Archimedes screw principle, providing ideal plug flow behavior. The crystallization process is realized through tube-in-tube cooling, which allows for adjustable temperature profiles along the ATC. As a result, the ATC is capable of providing a precise crystallization step with a narrow crystal size distribution at the outlet.

Further research focuses on the long-term operation of the ATC and the challenges associated with it, such as continuous seed generation and online measurement of particle size distribution. Additionally, the operation of the ATC with a different of substance systems and crystal shapes should be evaluated.
