Project title:

COMPARATIVE STUDY OF DIFFERENT TEMPERATURE MEASUREMENT TECHNIQUES APPLIED TO CHEMICAL LOOPING COMBUSTION

 

Research theme area:

Chemical looping combustion

 

Abstract:

Within the most promising carbon capture technologies, the chemical looping combustion (CLC) stands out [1]–[3]. Following this technology, CO2 capture is intrinsic to the combustion process in which the contact between fuel and oxidizer is circumvented by the usage of oxygen carriers (OC). Nevertheless, the commercial feasibility of such a technology requires that processes are conducted at moderate to high pressure values [4]–[6]. To attend this demand, packed bed reactors have been demonstrated to be a feasible constructive option [4], [5], [7]–[10]. A common aspect to the broad variety of the already published studies refers to the performance of low pressure experiments without a specific assessment of gas and OC temperatures. The lack of temperature information of both phases is a bottle neck for modeling improvements and to obtain a more comprehensive understanding about the underlying physics. Therefore, the main purpose of this research project is to investigate different temperature measurement techniques aiming to contribute with a better description of the temperature evolution of both participating phases in CLC reactors. Focus will also be given to operational strategies to control the temperature of the flue gas and the solid bed. For that, the realization of experimental measurements is indispensable. In a first stage, efforts will be concentrated in a quasi-one-dimensional CLC reactor similar to that originally proposed in [11] and further studied in [7]. With this reactor, different operating strategies will be evaluated. In a second stage, measurements will be conducted in a laboratory scale reactor with optical access, which will allow the evaluation of different temperature measurement techniques. Among the scheduled activities it stands out: the design and construction of reactors, utilization of laser-based diagnostic techniques and the usage of continuous gas analyzer. The proposed tasks are not only strictly connected with the Work Fronts 1, 2, and 6, but also with the first goal of the Work Stream A of the research project "Chemical Looping Combustion (CLC) and Oxy-fuel combustion with NG and Biogas".
The candidate will collaborate with researchers from the project 67 "Chemical Looping Combustion (CLC) and Oxy-fuel combustion with NG and Biogas" of the FAPESP-Shell Research Centre for Gas Innovation of POLI-USP at the University of São Paulo. Summary of the program and projects can be found at the RCGI website (http://www.rcgi.poli.usp.br/).

 

Description:

The applicant will contribute in line with the main objectives of the project:
1. Development and construction of reference reactors for model validation
2. Investigation of the usage of biomass based fuels in CLC

 

Requirements to fill the position:

This project would be well-suited to a highly motivated candidate to conduct activities based on reactor design, instrumentation, and experimental analysis for a CCS technology.
- The PhD candidate should be hold a bachelor in Engineering, preferentially in Chemical or Mechanical Engineering. It is wanted that the candidate holds a M.Sc. degree, which should have been obtained within the last five years.
