Short Presentation

Carsten Buchaly studied Chemical Engineering at the TU Dortmund University. In 2003, he graduated in Dortmund with a diploma thesis entitled “Phase interactions in turbulent gas-solid flows”. The scientific activities in his Ph.D. were focussed on experimental investigation, analysis and optimisation of hybrid separation processes. For his thesis on this subject he received the "EFCE Excellence Award in Process Intensification 2009". Since March 2008, Carsten is working as a process engineer in the competence center “Conceptual Design” at Bayer Technology Services, Leverkusen.

Member of research staff at the laboratory of fluid separations until December 2007 in the field of reactive distillation.

PhD Thesis

Experimental Investigation, Analysis and Optimisation of Hybrid Separation Processes

I worked on modelling, simulation and process analysis of a hybrid separation process, the combination of reactive distillation with membrane separation. The application is illustrated by the heterogeneously catalysed n-propyl propionate synthesis from 1-propanol and propionic acid. The membrane module is located in the distillate stream of the reactive distillation column in order to selectively remove the produced water without use of entrainers. For the stand-alone reactive separation process, the simulation results with a non-equilibrium model are in good agreement with experimental data obtained in a pilot-scale column. Additionally, a comparison of the most common modelling depths, namely the non-equilibrium model with Maxwell–Stefan equations, the equilibrium model taking into account reaction kinetics and the equilibrium model assuming chemical equilibrium, is presented. Vapour permeation experiments using Sulzer Pervap™ 2201(D) have been performed in a pilot-scale membrane plant in order to determine the separation characteristics for the dewatering of the non-ideal binary 1-propanol–water mixture. A first process analysis of the combined unit operations shows the influence of structural and operational parameters on the performance of the feasible hybrid process.

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”.
