Samenvatting:
For analysis of pre-combustion decarbonisation reactors and zero emission power plants a set of modelling tools is available. These tools have been developed or adapted and used at ECN in the CATO program on development of technology for power production with CO2 capture. The tools are used to asses the technical and economic feasibility of reduction of the energy penalty associated with CO2 capture. For this the thermodynamic efficiency and costs of CO2 capture are calculated using these models. A schematic of the use of modelling tools is provided in Figure 1.2. The central tool is Aspen Plus. This is a flow sheeting tool in which the whole power plant is modelled thermodynamically. It uses input from literature, experiments, detailed models and a separate gas turbine simulation program (GT-PRO). Separate from this, or integrated (for membrane reactors only) there are sorbent reactor or membrane reactor models for evaluation of the performance and design of these units. The results from Aspen Plus are used in an economic model. This estimates the main dimensions of all equipment and associated investments. It also calculates the costs of electricity and costs for CO2 avoidance. The Aspen Icarus Process Evaluator is a stand-alone programme that can be used for provide input for the economic model.
