Conclusions
In summary, in the experiment of ammonia defluorination and desulfurization , the
gas flow rate could be 1.5–2.0 m
3 /h and the liquid flow rate was 10–12 m
3 /h to
improve the contact density of gas–liquid two-phase mass transfer. The mass transfer
coefficient of the Bauer ring was higher than that of the stepped ring, and the mass
transfer coefficient of the DN 16 mm Bauer ring was higher than that of the DN
25 mm Bauer ring. In the experiment of defluorination and desulfurization with
ammonia water, the concentration of sulfur dioxide and hydrogen fluoride can be
reduced to 42 mg/m
3 and 0.8 mg/m
3 , respectively.
