Název v původním jazyce

Model design of operational parameters of a pilot scale carbonator

Popis výsledku v původním jazyce

The paper focuses on a mathematical model of carbonator, which is a key component of post-combustion CCS technology operating on the principle of calcium looping. The model considers a unit that processes flue gas from a 250 kW thermal power output combustion system. The carbonator is designed as a circulating fluidized bed reactor. One of the key points of the mathematical models is hydrodynamics of the fluidized bed reactor that is a basis for evaluation of the capture efficiency. It is generally difficult to estimate required parameters of fluidized bed, which may significantly differ from conditions in real device. For example it is axial and radial voidage profiles. Usually, part of these parameters is chosen according to the recommendations in available literature. In this paper the main attention is paid to the calculation of the hydrodynamics of the fluidized bed. Also sensitivity of the selected hydrodynamics parameters to the capture efficiency is subject of interest. The model results are basic operating characteristics of the carbonator.
