1-Dimensional modelling and simulation of the calcium looping process

Calcium looping is an emerging technology for post-combustion carbon dioxide capture and storage in development. In this study, a 1-dimensional dynamical model for the calcium looping process was developed. The model was tested against a laboratory scale 30 kW test rig at INCAR-CSIC, Spain. The study concentrated on steady-state simulations of the carbonator reactor. Capture efficiency and reactor temperature profile were compared against experimental data. First results showed good agreement between the experimental observations and simulations.

► 1-Dimensional models for carbonator and calciner were constructed.
► Carbonator model was validated with experimental results from a laboratory scale unit in Spain.
► Capture efficiency of the model was in good agreement with the experimental data.
► Temperature of carbonator reactor increases rapidly if cooling is not introduced shown with experiments and with the model.
► Also 1-dimensional temperature profile from the model showed good agreement with experiments.
