Travail de fin d'études et stage[BR]- Travail de fin d'études : Simulation and Adaptation of a Biomass Combined Heat and Power Plant with CO2 Capture[BR]- Stage d'insertion professionnelle

Abstract

This master’s thesis addresses the preliminary design of an amine-based, postcombustion CO2 capture pilot integrated into a biomass-fired CHP plant. Simulation models of the different subsystems (i.e. the biomass furnace, the thermodynamic cycle and the carbon capture unit) are developed with the software Aspen Plus. In particular, the performance of the capture unit is assessed and optimised. The submodels are then merged into a single model. This combined model offers an overview of the system as a whole and enables the prediction of interactions between the different subsystems. The repercussions of a localised change in operating conditions can therefore be measured. In addition to the modelling work, the capture unit is sized according to the identified nominal conditions. Energy integration within the existing plant is also investigated and the best compromise is identified. Finally, an order-of-magnitude cost estimation is calculated to support the decision making of the project.
