摘要

Abstract

Absorption of NO

into nitric acid solutions was studied in the presence of ozone by using a rotating packed bed(RPB) contactor.The influences of operating parameters

such as high gravity number

amount of ozone

gas velocity

liquid spray density and inlet concentration of NO

on the removal efficiency of NO

were investigated

among which the high gravity number and ozone amount are more important.Ozone was introduced to oxidize HNO

to HNO

to prevent the decomposition of HNO

in the liquid phase.The high gravity number presents the effective external force for enhancing the mass transfer of ozone from gas phase to liquid phase.Under the experimental condition

the removal efficiency of NO

is higher than 90%and the concentration of nitric acid product exceeds 45%.
