Abstract

A calcium looping (CaL) process is a carbon capture technology which
utilizes calcium oxide to remove carbon dioxide from the flue gas of a
power plant. Like most capture technologies, CaL process has a high
energy demand, which reduces power plant efficiency. The energy penalty
and the operating and capital costs of the unit can be reduced by
increasing the concentration of O2 in the oxidant flow to
calciner. In this study, a calciner has been studied with a three
dimensional, steady-state, CFB process model. First, the model was
validated by test data of the calciner in la Pereda CaL pilot. Next, a
3D model was created for a 200 MWth commercial scale calciner, in which
the inlet oxygen concentration was increased up to 75% to map the
potentials of improving the heat balance of the system and to
investigate how the calciner operates in these conditions. Based on the
simulations, the CaL process is feasible even at very high inlet oxygen
concentration.
