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.
