Modeling and Dynamic Analysis of CO2-Emission Free Power Processes in Modelica using the CombiPlant Library
Författare
Summary, in English
The need to reduce CO2 emissions from fossil-fuel
based power production creates the need for new
power plant solutions where the CO2 is captured and
stored or reused. Different concepts to capture CO2
fall into the three main categories:
1. Precombustion decarbonization
2. Oxy-fuel combustion
3. Post-combustion removal of carbon.
In the first two types of processes Oxygen Transport
Membrane (OTM) is the key component, as pure
oxygen is usually required to process reactions (e.g.
Integrated Gasification Combined Cycle IGCC, Advanced
Zero Emission Plant AZEP). Post-combustion
removal processes can for example utilize adsorption/
desorption in certain salt solutions. This paper
will describe two different applications of CO2-
emission-free processes, one using an OTM, the other
a high pressure post combustion removal process, the
Sargas process, which has been modeled in a project
with Siemens Industrial Turbomachinery AB and Alstom
Power Sweden AB. All modeling work was carried
out in the modeling language Modelica, which is
an open standard for equation-based, object-oriented
modeling of physical systems. System models have
been built using the CombiPlant library, a modeling library for combined cycle power plants from Modelon
AB.
