Maximale Anzahl der Teilnehmer: 6

Beschreibung: The trend towards the development of chemical processes with efficient energy consumption, minimal environmental impact and safe operation is nowadays ubiquitous in the process industry and imposes significant challenges that should be foreseen at the early stages of the process design, when the new technologies are being evaluated. Within this context, the continuous monitoring of the process efficiency plays a significant role during the evaluation of promising technologies and simultaneously offers guidelines for the optimization of their performance. In this project a platform for the online monitoring of a continuously operated miniplant will be built. This includes the development of different modules for signal processing, data validation, analysis and a GUI where the relevant information is displayed.

OBJECTIVE: The main goal of the project is to improve the available interface of the control system of a novel chemical process that is being evaluated in a miniplant scale as well as the development of new capabilities for the online monitoring of key performance indicators (e.g. E factor, turnover frequency, resource efficiency) and their visualization. This involves the application (and when needed, the development) of modules for data processing, estimation and visualization of key process variables. By the end of project it is expected not only the delivery of the platform and its corresponding user manual but also its commissioning in the real plant.

TASKS: It is responsibility of the participants to organize their work in the most suitable way in order to achieve the project goal. However, some guidelines can be provided for what to expect in the project. The work can be divided into six work packages (WP):
• WP1: Data acquisition. In this work package the data acquisition capabilities of the available system will be improved. Specifically, data from one of the analyzers (currently available off line) should be communicated online to the miniplant control system. This issue can be addressed by a TCP/IP protocol in an internal network.
• WP2: Data processing. In this work package simple tools for signal filtering and preprocessing will be implemented. Some progresses have been already done in this direction: different tools have been built in MATLAB and validated with historical data. In this work package a module that integrates the MATLAB tools with the control systems in LabVIEW will be developed. The expected output is preprocessed data that be used by other modules in the platform.
• WP3: Data reconciliation and estimation of performance indicators. Filtered and preprocessed data from WP2 will be used in WP3 for correction of the measured variables in order to fulfill basic first principle laws as mass balances. Analogous to WP3, the developed module integrates MATLAB and LabVIEW. The expected output are reconciliated measurements and key performance indicator that will be used by WP4.
• WP4: Graphical User Interface. The available GUI (in LabVIEW) will be extended for monitoring and reporting purpose. A reporting service should be included; where different process parameters are displayed according to the online information.
• WP 5: Commissioning. Delivery of the final product and evaluation in the real process.
• WP 6: Documentation As an output of the project a user manual of the platform is requested.

REQUIREMENT: The participant should possess basic programming skills, preferably in LabVIEW, MATLAB and Visual Basic. Knowledge of process optimization and control is appreciated. It is not required to have a deep knowledge in chemical processes.
REGULATIONS: The project seminar is worth 12 credit points, which equals a workload of 360 h per student (including 90 h for final and weekly presentations, and for all documentation including the final written report). Participation in all regular (weekly) meetings with the supervisors is obligatory. All participants have to document and present their work regularly. The project seminar will not be graded, but we will exclude students from the project who do not participate actively. We recommend (but do not require) that the project group finishes before the beginning of the exam period.
