Influence of gas components on removal of SO_2 from flue gas in the semidry FGD process with a powder-particle spouted bed

摘要

The influences of CO_2 and O_2 on SO_2 removal from flue gas using a powder-particle spouted bed were investigated. The experimental results showed that O_2 concentration does not affect SO_2 removal from flue gas in the experimental range. The influence of CO_2 on SO_2 removal was found to depend on the approach to saturation temperature (ΔT_a), which is the difference between bed temperature and adiabatic saturation temperature.
