Projektbeskrivning (Project description):
This project is to develop a novel power generation cycle with a flameless combustion
process with inherent CO2 separation, which offers the feature for reducing CO2
emissions. In the process, the fuel is oxidized by a solid oxygen carrier. This oxygen
carrier is then re-oxidized by air in a separate reactor. Because of the two-step
combustion, CO2 can be obtained in a separate stream without significant energy loss.
This process is known as Chemical Looping Combustion (CLC). This project is to
investigate the performance of CLC systems with integration of the experimental
studies on oxygen carrier and reactors which are included in a parallel project by
Chalmers University of Technology (CTH) Initial system studies are to provide the
conditions and requirements for experiments. Based on the experimental results on
oxygen carriers and reactors, an in-depth modeling of systems will focus on the
optimization of the processes and reducing irreversibilities of the components. The
project will give experience and knowledge for the construction of a minor pilot plant
to demonstrate this technology.
Projektets mål (Project goal):
The goal of the project is to demonstrate the potential of the new technology for
industrial application by investigating the whole system. In the later phase of the
project (Year 2004/05), a Ph.D. student is expected to finish a Ph.D. degree.
1. Configure and identify potential power generation processes with CO2 capture.
2. Initial system studies to identify desirable reactor conditions such as temperature,
pressure, and conversion degree etc.
3. Study the impact of different oxygen carrier on the process design and efficiency
of the system.
4. Further system studies by using results from experimental work on oxygen carrier
and reactor design (data from CTH).
