The project module is intended to introduce the students to their later professional activities through concrete tasks and practical work. The students have the opportunity to carry out this project module in the Technical Chemistry Laboratory. Here they work on current research topics independently but nevertheless under the competent guidance of our professors and doctoral students. In most cases, the project module is followed by the Bachelor's thesis on the same or a similar topic. This gives the students the opportunity to deal with a topic in depth over a longer period of time (approx. 6 months). However, students can also work on a topic independent of the Bachelor's thesis.

Further information can be found in the respective examination regulations and the responsible professors.

Admission requirements

Examination regulations for the Bachelor's and Master's degree programmes in Chemical Engineering at the Hochschule Niederrhein dated 31.07.2009 (Amtl. Bek. HN 13/2009), amended by regulations dated 7 August 2012 (Amtl. Bek. HN 20/2012), last amended by regulations dated 2 June 2014 (Amtl. Bek. HN 6/2014).

There are no explicit admission requirements according to the examination regulations. However, care is taken to ensure that the project module is not carried out until shortly before the Bachelor thesis towards the end of the Bachelor studies. Only then will the students have acquired a solid technical foundation through their studies and be able to draw on the contexts learned during the project assignment.

Examination regulations for the Bachelor's degree programme in Chemical Engineering at the Hochschule Niederrhein dated 15.08.2017 (Amtl. Bek. 51/2017).

Admission to the project module is granted when all 119 credit points have been acquired from the first four semesters of the full-time Degree programme and all course attendance certificates (abbreviated in module list: attendance certificate) have been completed. The project module is thus usually carried out in the sixth semester (of the full-time Degree programme), covers a continuous period of 16 weeks and is to be completed without division.
Registration for the project assignment

The registration for the project assignment and the selection of possible topics is done directly with the responsible professors.

Please contact our doctoral students, Mrs. Schramm or the respective professor directly.

The project module is usually completed in the third semester of the Master's degree programme in chemical engineering and comprises a total of 6 SWS. Within the scope of the project module, the students work on practical or theoretical topics from the field of chemical engineering or engineering research. The task for the students is to independently acquire missing knowledge with which the technical problems can be solved. For this purpose, inventive talent is often required. The solutions are to be documented according to engineering standards.

The project module offers students the opportunity to deal intensively with topics from the following areas:

• Planning and construction of experimental plants
• Feasibility studies
• Process engineering studies
• Cooperation in research projects

As a rule, two projects on different topics are carried out. If possible, the projects should be selected from two different areas. Group work of up to four persons is permitted.

The range of topics for the project assignments is constantly updated An up-to-date list of suggested topics can be downloaded from Sciebo at the Hochschule Niederrhein. You will receive the password after consultation with Ms. Schramm.

As proof of completed projects, the students are required to keep a so-called testate card (see also Vertiefungspraktikum). This card is signed by the university teacher / lecturer after the course has been successfully completed. The 18 CPs can only be booked on the students' status sheet once the testat card has been completed in full. The in-depth internship to be carried out in the Master's program is also noted on the certificate card. More information about this can be found on the respective website.

Download of the master testat card (PO 2017) (the password can be obtained from Mrs. Schramm).

Registration for the project assignment

The registration for the project assignment has to be done directly with the responsible professors. Please contact our PhD students, Mrs. Schramm or directly the respective professor.

At the end of every studies there is a thesis. In the Technical Chemistry Laboratory, students have the opportunity to write their thesis (bachelor's or master's thesis) on current topics in Technical Chemistry and on interesting research projects (see "Our doctoral students introduce themselves"). In the case of Bachelor's theses, this is usually done after successful completion of the project assignment on the same topic or on a topic derived from it. An internal thesis is highly recommended if students can imagine a future career in a research and development department or in academic research. Those who are aiming for a doctorate should also consider an internal thesis, as this allows them to learn and practice strictly scientific work in a structured manner at an early stage.

Bachelor's thesis

In the Bachelor's thesis, students are required to work on a practical task with a practical emphasis / orientation, both in its subject-specific details and in its interdisciplinary contexts, within a specified period of time. Scientific and application-oriented methods are to be applied. The Technical Chemistry Laboratory provides the necessary resources and exciting and current topics in the field of research. The students are supported during their work by our doctoral students and the respective supervising professor.

To get an impression of the possibilities the Technical Chemistry Laboratory can offer you in the context of your Bachelor's thesis, here is a small excerpt of Bachelor's theses carried out in our laboratory during the last semesters:

• Design and measurements of a stirred tank system with steam heating.
• Experimental investigations of heat transfers at coil internals in a reactor model.
• Investigation of UV-activated heterogeneous catalysis in connection with the usability of catalyst particles as tracer/seeding particles in PIV measurements.
• Investigation of the influence of the agitated flow profile on gas hydrate formation in an autoclave using dimensionless indices.
• Measurement and calculation of heat transfers in stirred reactors with coil internals.
• Optical investigation of suspension and dispersion processes in a temperature-controlled stirred reactor with immersed tube coils.
• Investigation of the influence of tube baffles on flow behavior in a stirred tank using stereo PIV.
• Application of a high-speed camera system to process engineering experiments.
• Thermodynamic study of the formation of gas hydrate surfaces.
• Investigation of factors influencing induction time during methane hydrate formation under pipeline-like conditions.

Master's thesis

The master's thesis comprises a challenging problem from the field of Technical Chemistry. Largely independently - under the supervision of doctoral students and professor - the students carry out practical work on a current topic (research projects in Technical Chemistry). This includes the planning and selection of suitable experiments, their evaluation and critical consideration of the results obtained. The aim of the Master's thesis is to significantly expand the students' system and methodological competence and to prepare them for the high demands of working as a chemical engineer in the professional world.

To get an impression of the possibilities the Technical Chemistry Laboratory can offer you in the context of your master's thesis, here is a small excerpt of master's theses carried out in our laboratory during the last semesters:

• High pressure studies on the kinetics of gas hydrate formation under the influence of different inhibitors.
• Feasibility study for the implementation of a stirred reactor in the CFD program OpenFOAM®.
• Implementation and commissioning of a stereo PIV measurement system.
• Investigation of the representability of the mixing time behavior of stirring processes using the CFD software OpenFOAM®.
• Development of inhibition concepts to avoid the formation of methane hydrates in pipeline-like systems.
• Feasibility study for the simulation of heat transfer processes in the CFD software OpenFOAM®.
• Investigation of heat exchange and mixing behavior on helical coils in stirred reactors using laser-induced fluorescence.
